3-phase high voltage inverter power board for FOC and scalar
motor control based on the STGIPN3H60 (SLLIMM™-nano)
Introduction
The 3-phase high voltage inverter power board features the STGIPN3H60 (SLLIMM™nano) for both field-oriented control (FOC) of permanent magnet synchronous motors
(PMSM) and trapezoidal scalar control of brushless DC (BLDC) motors. Also referred to by
the order code STEVAL-IHM035V2, this 3-phase inverter is designed to perform both the
FOC of sinusoidal-shaped back-EMF PMSMs and trapezoidal control of BLDC motors with
or without sensors, with nominal power up to 100 W. The flexible, open, high-performance
design consists of a 3-phase inverter bridge based on:
• The STGIPN3H60 SLLIMM™-nano (small low-loss intelligent molded module) IPM, 3 A 600 V 3-phase IGBT inverter bridge
• The VIPer16 fixed frequency VIPer™ plus family
The system is specifically designed to achieve fast and accurate conditioning of the current
feedback, thereby matching the requirements typical of high-end applications such as field
oriented motor control.
The board is compatible with 110 and 230 Vac mains, and includes a power supply stage
with the VIPer16 to generate the +15 V and the +3.3 V (or optionally the +5 V) supply
voltage required by the application. Finally, the board can be interfaced with the
STM3210xx-EVAL (STM32 microcontroller evaluation board), STEVAL-IHM022V1 (high
density dual motor control evaluation board based on the STM32F103ZE microcontroller),
and with the STEVAL-IHM033V1 (control stage based on the STM32F100CB
microcontroller suitable for motor control), through a dedicated connector.

Of the above motor control system architecture, the STEVAL-IHM035V2 includes the power
supply and power hardware blocks.
The power block, based on the high voltage STGIPN3H60 (SLLIMM™-nano), converts the
signals coming from the control block into power signals capable of correctly driving the 3phase inverter, and therefore the motor.
The power supply can be fed with 110 or 230 Vac mains, and the maximum allowed input
power is 100 W at 230 Vac (refer to Section 6).
In the control block, an MC connector is mounted on the STEVAL-IHM035V2 and the
STM3210xx-EVAL, STEVAL-IHM022V1, and STEVAL-IHM033V1, which allows the STM32
microcontroller evaluation board to be used as a hardware platform for development.
The “STM32 FOC firmware library” is ready to be used in conjunction with the STM32 MC
workbench 1.2 as a software platform for the sensorless control of PMSMs (see Section 9).
The required STM32 motor control workbench data is reported in Table 4.

Electrical characteristics of the board
Electrical characteristics of the board
Board power is intended to be supplied by an alternate current power supply through
connector J7 (AC mains) or optionally by a direct current power supply through connector J8
(DC bus), in which case it is required to respect the correct polarity.
Stresses above the limits shown in Table 1 may cause permanent damage to the devices
present inside the board. These are stress ratings only and functional operation of the
device under these conditions is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
A bias current measurement may be useful to check the working status of the board. If the
measured value is considerably higher than the typical value, some damage has occurred
to the board. Supply the board using a 40 V power supply connected to J8, respecting the
polarity. When the board is properly supplied, LED D16 is turned on.

Board architecture
The STEVAL-IHM035V2 can be schematized as shown in Figure 5.
Figure 5. STEVAL-IHM035V2 block diagram
7.1
Power supply
The power supply can address an AC input voltage (J7) ranging from 30 Vac up to 270 Vac.
The alternating current input is rectified by a diode bridge and a bulk capacitor to generate a
direct current bus voltage approximately equal to √2 Vac (neglecting the voltage drop across
the diodes and the bus voltage ripple). A VIPer16 is then used in a buck converter
configuration to generate the +15 V supply voltage of the gate drivers and to supply the low
drop voltage regulators (LD1117S33TR) to generate the 3.3 V and (LD1117S50TR) to
generate the 5 V that can be used as Vdd microcontroller reference voltage selecting
jumper J10. It is possible to also provide the microcontroller supply voltage to the control
board via motor control connector J1.
7.2
Gate driving
As mentioned previously, gate driving of the switches is performed inside the STGIPN3H60
IPM.

7.3
Board architecture
Hardware overcurrent protection
The hardware overcurrent protection is implemented using the fast shutdown feature of U2
(STGIPN3H60).
A fault signal is also fed back to the J1 connector if the overcurrent event is detected.
See Section 8.1 for more detailed information on hardware current protection.
7.4
Amplifying network for current measurement
The voltages across the shunt resistor are amplified by Aop amplification gains to correctly
condition the current feedback signals and optimize the output voltage range for a given
phase current range and A-D converter input dynamics. Refer to Section 8.3 for more
detailed information on how to dimension the op amp conditioning network depending on
user needs.
To implement the current measurement network, the operational amplifier present in U2
(STGIPN3H60) is used.
7.5
Temperature feedback
Temperature feedback is performed by way of an NTC placed below the package of the
STGIPN3H60. It enables the monitoring of the power stage temperature so as to prevent
any damage to the inverter caused by overtemperature.
7.6
BEMF zero crossing detection network
The BEMF detection network allows the following strategies of BEMF sampling:
•
BEMF sampling during off-time (ST patented method)
•
BEMF sampling during on-time
•
Dynamic method based on the duty cycle applied.
For more details see the STM8S 3-phase BLDC software library v1.0 (UM0708).
7.7
BLDC current limitation/regulation network
The current regulation/regulation network is used to adapt the signal to perform the cycleby-cycle current control in the BLDC drive. See the STM8S 3-phase BLDC software library
v1.0 (UM0708) for more details. To implement the current limitation/regulation network the
external comparator U1 (TS3021ILT) is used.
7.8
Overcurrent boost network
On the STEVAL-IHM035V2 board the overcurrent boost network that allows, in run time, a
temporary rise of the hardware overcurrent protection threshold is present. See Section 8.2
for more details.

Hall sensor/quadrature encoder inputs
The board is easily configurable to run the motor using the Hall sensors or quadrature
encoder as position/speed feedback changing the jumpers J3, J4 and J5 and connecting
the sensor signals to connector J2.
Note:
The Hall sensors or quadrature encoder sensor is not power supplied by STEVALIHM035V2.
The default configuration is intended for push-pull sensors. The R8, R11 and R12 resistors
are used to limit the current injected into the microcontroller if the sensor high voltage is
above Vdd-micro.
The maximum current injected should be less than the maximum present in the
microcontroller datasheet.
If the sensor has open drain outputs it is possible to mount the pull-up resistors R2, R3 and
R4.

Overcurrent protection
Hardware overcurrent protection has been implemented on the board, taking advantage of
the comparator integrated inside the STGIPN3H60. The internal connection between the
comparator output and the shutdown block makes the intervention time of the overcurrent
protection extremely low, slightly above 100 ns.
Since the overcurrent protection acts as soon as the voltage on CIN rises above the internal
reference equal to 0.5 V, and given the default value of the shunt resistors (equal to 0.47 Ω),
it follows that the default value for the maximum allowed current (ICP) is equal to:
Equation 1
V Ref
I CP = ----------------- ≅ 1106
.
R shunt
If necessary, the overcurrent threshold can be modified changing the value of shunt resistor
R43.
8.2
Overcurrent boost
Overcurrent boost can be requested by an application during, for instance, the motor startup
or during an active brake. The STEVAL-IHM035V2 includes an overcurrent boost feature, it
is possible to increase temporarily the hardware overcurrent protection threshold using the
“OC Boost” signal present in the motor control connector J1 (pin 23). This signal is intended
to be high impedance when not active while set to GND when active. The default values of
the overcurrent threshold and the “OC Boost” signal activation logic are reported in Table 2.

R42 is 0 Ω.

resistors.

Jumper configuration
This section provides jumper settings for configuring the STEVAL-IHM035V2 board.
Two types of jumpers are used on the board:
•
3-pin jumpers with two possible positions; the possible settings for which are presented
in the following sections.
•
2-pin jumpers with two possible settings; fitted if the jumper is closed, and not fitted if
the jumper is open.
The STEVAL-IHM035V2 board can also be configured using a set of 0 Ω resistors. These
resistors are used as 2-pin jumpers with two possible settings: mounted and not mounted.
8.4.1
Microcontroller supply voltage
The microcontroller supply voltage fed to J1 pin 28 through the R7 resistor is selected using
jumper J10:
8.4.2
•
J10 between pin 1 and 2 (default setting): select Vdd micro (J1 pin 28) to +3.3 V
•
J10 between pin 2 and 3: select Vdd_micro (J1 pin 28) to +5 V.
Current sensing network settings
The current sensing network can be configured for bipolar current reading or for unipolar
current reading.
In the first case (bipolar current reading), the current flows in the shunt resistor in both
directions: to the ground and from the ground. This is sinusoidal control and the current
sensing network must make sure to add an offset value in order to measure the negative
values.
In the second case (unipolar direction) the current flows only in one direction: to the ground.
This is trapezoidal control and the current sensing network is not required to add an offset.
Anyhow, it is possible to add a small offset to avoid the saturation of the op amp to the
minimum value for low value of motor current.
Resistor R37 is used to select the value of the offset added by the current sensing network.
•
R37 mounted (default setting): The current sensing network adds an output offset of
1.86 V (See Section 8.3). This configuration should be used for sinusoidal control.
•
R37 not mounted: The current sensing network doesn't add any offset.
Resistor R50 can be used to change the amplification gain of the current sensing network,
see Equation 2 and 3.
22/41
•
R50 equal to 0 Ω (default setting): The current sensing network amplification gain value
is set to 2.91. This configuration should be used for sinusoidal control having a
Vdd_micro = 3.3 V.
•
R50 equal to 5.6 kΩ: The current sensing network amplification gain is increased by
adding a 5.6 kΩ resistor in series to the R48 and R49 (see Section 8.3). This
configuration can be used for trapezoidal control having a Vdd_micro = 5 V. If R37 is not
mounted and R50 is 5.6 kΩ, the current sensing network amplification gain value is 12.
DocID022781 Rev 2
UM1517
8.4.3
STEVAL-IHM035V2 schematic diagrams
Bus voltage divider setting
The default value of the bus voltage divider is sized to scale up to 400 V of DC bus voltage
to 3.3 V maximum voltage. By changing resistor R54 it is possible to modify the bus voltage
divider.
•
R54 equal to 8.2 kΩ (default setting): The bus voltage divider value is 125. This
configuration can be used having a Vdd_micro = 3.3 V.
•
R54 equal to 12 kΩ: The bus voltage divider value is 88. This configuration can be used
having a Vdd_micro = 5 V.
Note:
The value of the bus voltage divider is computed considering the 100 kΩ resistor present in
the voltage sensing input of the control stage.
8.4.4
Position feedback jumper setting
On the STEVAL-IHM035V2 board two position feedback networks are present: BEMF zero
crossing detecting network and Hall sensors/quadrature encoder sensor conditioning
network.
To select which of the two networks is connected with the motor control connector, jumpers
J3, J4 and J5 are used.
8.4.5
•
J3, J4 and J5 between pin 1 and pin 2 (default setting): The Hall sensors/quadrature
encoder sensor conditioning networks are fed into the motor control connector.
•
J3, J4 and J5 between pin 2 and pin 3: The BEMF zero crossing detecting networks
are fed into the motor control connector. The BEMF zero crossing is possible only in
trapezoidal control.
BEMF zero crossing detection network enabling
The BEMF zero crossing detection networks can be disabled removing the following
resistors R14, R21 and R30.
8.4.6
•
R14, R21 and R30 mounted (default setting): The BEMF zero crossing detection
network is enabled. The BEMF zero crossing is possible only in trapezoidal control.
•
R14, R21 and R30 not mounted: The BEMF zero crossing detection network is
disabled. If not required, it is possible in this way to cut off unwanted power
consumption.
Motor control connector extra features enabling
If these extra features are not supported by the control board, it is possible to disable it
removing the following resistors; R1, R5, R9 and R10.
•
R9 and R10 mounted (default setting): enables the cycle-by-cycle current regulation for
trapezoidal control.
•
R9 and R10 not mounted: disables the cycle-by-cycle current regulation for trapezoidal
control.
•
R1 mounted (default setting): enables the dynamic BEMF zero crossing sampling
(during TON or during TOFF) for trapezoidal control.
•
R1 not mounted: disables the dynamic BEMF zero crossing sampling (during TON or
during TOFF) for trapezoidal control.
•
R5 mounted (default setting): enables the overcurrent boost.
•
R5 not mounted: disables the overcurrent boost.

Using the STEVAL-IHM035V2 with the STM32 FOC firmware library

UM1517
Using the STEVAL-IHM035V2 with the STM32 FOC
firmware library
The “STM32 FOC firmware library v3.0 or later” provided together with the STM3210BMCKIT performs the field-oriented control (FOC) of a permanent magnet synchronous
motor (PMSM) in both sensor and sensorless configurations.
It is possible to configure the firmware to use the STEVAL-IHM035V2 as power stage
(power supply plus power block of Figure 2) of the motor control system.
This section describes the customization to be applied to the “STM32 FOC firmware library”
in order for the firmware to be compatible with the STEVAL-IHM035V2.
9.1
Environmental considerations
Warning:
The STEVAL-IHM035V2 evaluation board must only be used
in a power laboratory. The voltage used in the drive system
presents a shock hazard.
The kit is not electrically isolated from the DC input. This topology is very common in motor
drives. The microprocessor is grounded by the integrated ground of the DC bus. The
microprocessor and associated circuitry are hot and MUST be isolated from user controls
and communication interfaces.
Warning:
Any measurement equipment must be isolated from the main
power supply before powering up the motor drive. To use an
oscilloscope with the kit, it is safer to isolate the DC supply
AND the oscilloscope. This prevents a shock from occurring
as a result of touching any single point in the circuit, but
does NOT prevent shock when touching two or more points
in the circuit.
An isolated AC power supply can be constructed using an isolation transformer and a
variable transformer.
Note:
26/41
Isolating the application rather than the oscilloscope is highly recommended in any case.

9.2
Using the STEVAL-IHM035V2 with the STM32 FOC firmware library
Hardware requirements
The following items are required to run the STEVAL-IHM035V2 together with the “STM32
FOC firmware library”.
9.3
•
The STEVAL-IHM035V2 board and MB525 board (STM32 evaluation board with MC
connector) or any other evaluation board with an MC connector, such as the STEVALIHM022V1, STEVAL-IHM033V1, MB871, or MB672
•
A high voltage insulated AC power supply up to 230 Vac
•
A programmer/debugger dongle for the control board (not included in the package).
Refer to the control board user manual to find a supported dongle. Use of an insulated
dongle is always recommended.
•
A 3-phase brushless motor with permanent magnet rotor (not included in the package)
•
An insulated oscilloscope (as necessary)
•
An insulated multimeter (as necessary).
Software requirements
To customize, compile and download the “STM32 FOC firmware library”, a toolchain must
be installed. Please check the availability on STMicroelectronics website or contact your
nearest STMicroelectronics office to obtain documentation relevant to the “STM32F103xx or
STM32F100xx PMSM single/dual FOC SDK” and refer to the control board user manual for
further details.
9.4
STM32 FOC firmware library customization
To customize the STM32 FOC firmware library the “ST motor control workbench” can be
used.
The required parameters for the power stage related to the STEVAL-IHM035V2 are
reported in Table 4.

Using the STEVAL-IHM035V2 with the STM8 3-phase BLDC firmware library
Using the STEVAL-IHM035V2 with the STM8 3-phase
BLDC firmware library
The “STM8 3-phase BLDC firmware library v1.0” provided together with the STM8-MCKIT
performs the brushless direct current motor (BLDC) scalar control of a permanent magnet
synchronous motor (PMSM) in both sensor and sensorless configurations.
It is possible to configure the firmware to use the STEVAL-IHM035V2 as power stage
(power supply plus power block of Figure 2) of the motor control system.
This section describes the customization to be applied to the “STM8 3-phase BLDC
firmware library v1.0” in order for the firmware to be compatible with the STEVALIHM035V2STEVAL-IHM035V2.
10.1
Environmental considerations
Warning:
The STEVAL-IHM035V2 evaluation board must only be used
in a power laboratory. The voltage used in the drive system
presents a shock hazard.
The kit is not electrically isolated from the DC input. This topology is very common in motor
drives. The microprocessor is grounded by the integrated ground of the DC bus. The
microprocessor and associated circuitry are hot and MUST be isolated from user controls
and communication interfaces.
Warning:
Any measurement equipment must be isolated from the main
power supply before powering up the motor drive. To use an
oscilloscope with the kit, it is safer to isolate the DC supply
AND the oscilloscope. This prevents a shock from occurring
as a result of touching any single point in the circuit, but
does NOT prevent shock when touching two or more points
in the circuit.
An isolated AC power supply can be constructed using an isolation transformer and a
variable transformer.
Note:
Isolating the application rather than the oscilloscope is highly recommended in any case.

Hardware requirements
The following items are required to run the STEVAL-IHM035V2 together with the “STM8 3phase BLDC firmware library v1.0”.
Note:
•
The STEVAL-IHM035V2 board and MB631 board (STM8 evaluation board with MC
connector)
•
A high voltage insulated AC power supply up to 230 Vac
•
A programmer/debugger dongle for control board (not included in the package). Refer
to the control board user manual to find a supported dongle. Use of an insulated dongle
is always recommended.
•
A 3-phase brushless motor with permanent magnet rotor (not included in the package)
•
An insulated oscilloscope (as necessary)
•
An insulated multimeter (as necessary).
To make the MB631 board compatible with the BLDC drive, it is necessary to check if the
required modifications explained in UM0709 (appendix A.1) have been properly carried out.
The MB843 (BLDC daughterboard) available in the STM8 MC-KIT can be used for BLDC
sensing and for the current regulation/limitation, otherwise wire connections on the
extension connector present in the MB631 are required to feed the proper signal coming
from the MC connector to the right microcontroller inputs/outputs, see Table 5 for sensorless
drive and Table 6 for sensored drive.
