Introduction
The Evaluation Kit “EASYKIT AUX DRIVES” was developed to support customers during their first steps in
designing applications with the Easy 1B Automotive B6-Bridge power module. These modules are targeted
for high voltage pumps and compressor applications within hybrid- and electric vehicles.
The application note explains how to start with the Evaluation Kit and explains the design. The information is
intended to enable the customers to re-use and modify the Evaluation Kit design for their own specific
requirements.
1.1
Safety Warning for Evaluation KIT
Please read and understand the manual and the following safety warnings.
The design operates with unprotected high voltages. Therefore, the Evaluation Kit may
only be handled by persons with sufficient electrical engineering training and experience.
The customer assumes all responsibility and liability for its correct handling and/or use of
the Evaluation Kit and undertakes to indemnify and hold Infineon Technologies harmless
from any third party claim in connection with or arising out of the use and/or handling of the
Evaluation Kit by the customer.
The Evaluation Kit is a sample to be used by the customer solely for the purpose of evaluation and testing. It
is not a commercialized product and shall not be used for series production.. The Evaluation Kit is thus not
intended to meet any automotive qualifications. Due to the purpose of the system, it is not subjected to the
same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and
Product Withdraw (PWD) as regular products. See Legal Disclaimer and Warnings for further restrictions on
Infineon Technologies warranty and liability.

Quick Start Guide
Before operating this Evaluation Kit two steps are necessary:
1. Mount system on a cooling plate
2. Connect aux supply, HV supply and a 3phase AC motor (or alternative load)
3. Motor starts running automatically per default (see chapter 4 for CAN control modes)
Please read the entire application note carefully in order to prevent accidents and damage on the
Evaluation Kit.
2.1
Mount System on a Cooling Plate
The power module can be attached directly on a cooling plate after applying a thermal grease of 50 um
thickness (e.g. Fischer WLP). Detailed information on the mounting of the Easy Automotive Module can be
found in [2].
thermal grease
Cooling System
Figure 2 Mounting for quick start with the Evaluation Kit. Standard thermal grease is applied between
module and cooler. The module is fixed with screws via the module integrated clamps. See
Application Note [2] for recommended mounting instructions.
The cooler design depends on the specific requirements of the target system. The highest performance and
power density can be achieved with water cooling systems. Nevertheless, forced air cooling is typically
easier for first tests in the high voltage lab. An example of a forced air cooler was designed, where the DCLcapacitor was placed on the bottom of the PCB to achieve a compact system design (see Figure 3). The
drawings for the sample air cooler can be taken from Figure 4.
Measurements with the cooler prototype Assmann WSW: ASS_1060_HSrev01 and FAN: AFB0612VHC
running at 15 V showed an Rth (heatsink to ambient) of approximately 0.4 K/W.

Connect Supplies and Load
The Evaluation KIT has to be connected to a 8..18V auxiliary supply, which can deliver at least 2A. On the
HV power connectors a supply <450V and a 3ph induction machine (or equivalent load) has to be applied.
The connections are illustrated in Figure 5.
Please take note that only the aux supply is reverse polarity protected up to -20V. The power terminals for
the <450V DCL supply is not protected against reverse polarity events and will lead to failed diodes if current
is not limited.

Operation of Power Board only
Some investigations, like typical double pulse switching tests, are easier to perform without a control board
and software. The pulse patterns are generated here from a function generator.
For such an operation, the power board needs some minor modifications. Three zero ohm bridges has to be
placed. The location for these bridges are illustrated in Figure 6.

Operating Modes and LED status
4.1
Mode 1 (Default): Self test, soft start, and motor rotation
This mode is selected per default in the standard delivery condition. After the Evaluation Kit has an
appropriated supply voltage, first a self test is performed and after PASS result the phase output is ramped in
a soft start function to a fixed output frequency. The induction machine is running open loop. All of these
items are performed automatically and it requires no user interaction, which makes first test “Easy”.
Safety Warning: Please note that the motor is starting to rotate automatically in this operating mode.
Make sure that the motor is fixed properly and a motor rotation will not lead to dangerous situations
for persons in the near environment.
4.2
Mode 2 (Jumper): CAN controlled mode for output frequency and voltage
If a Jumper is placed on the diagnosis header between pin 12 and 13, the Evaluation Kit runs in CAN Mode.
The easiest way to use the CAN functionality is given with the CAN terminal function. Please see chapter 5
for more information of this low cost terminal solution.
JUMPER position for
CAN control mode
Figure 8 Required jumper position for enabling the CAN controlled mode.
After the self test routine is successfully passed it waits for CAN messages. In this mode the output
frequency and voltage for the motor can be programmed to adjust the motor speed.
Following CAN Messages are minimum required to get the motor running:
-
The nominal output voltage (line to line) has to be applied with CAN Message:
CAN-ID 11hex, Signal Name PVacNom, Data Type Unsigned, Bit Start 16, Bit Length 16, Unit V Q4 (16 ↔ 1 V)

-
The nominal output frequency has to be applied with CAN Message:
CAN-ID 11hex, Signal Name PFacNom, Data Type Unsigned, Bit Start 0, Bit Length 16, Unit Hz Q6 (64 ↔ 1
Hz)
-
The target output frequency has to be applied with the CAN Message:
CAN-ID 10hex, Signal Name DFacSet, Data Type Signed (negative value for change of rotation direction), Bit
Start 16, Bit Length 16, Unit Hz Q6 (64 ↔ 1 Hz)
-
The motor starts to run after CAN Message:
CAN-ID 10hex, Signal Name DEnable, Data Type Bit, Bit Start 0, Bit Length 1
-
4.3
The target frequency can now be continuously adjusted and will be slowly ramped to these new
values.
Mode 3 (Jumper): CAN controlled low side single pulse test
The CAN controlled mode (required jumper position see Figure 8) allows single pulse switching tests on an
arbitrary low side switch without the need of a function generator. The easiest way to use the CAN
functionality is given with the CAN terminal function. Please see chapter 5 for more information of this low
cost terminal solution. The single pulse test is a useful mode if you want to test turn-off overvoltages. For
these tests a power inductor has to be connected between the phase output and DCL+ connection like in
standard double pulse test benches (see Figure 22, Figure 24, Figure 26, Figure 28 for pulse test
configurations).
-
This mode can be entered if a Jumper is placed on the diagnosis header between pin 12 and 13
(similar to Mode 2).
Following CAN Message is required to enter single pulse testing:
CAN-ID 10hex, Signal Name DSglPulse, Data Type Bit, Bit Start 2, Bit Length 1
-
The switch has to be selected with CAN Message (multiple or a single switch can be selected):
CAN-ID 10hex, Signal Name DSglPulseULs, Data Type Bit, Bit Start 3, Bit Length 1
CAN-ID 10hex, Signal Name DSglPulseVLs, Data Type Bit, Bit Start 4, Bit Length 1
CAN-ID 10hex, Signal Name DSglPulseWLs, Data Type Bit, Bit Start 5, Bit Length 1
-
The pulse length has to be applied with CAN Message:
CAN-ID 10hex, Signal Name DSglPulseLength, Data Type Unsigned, Bit Start 16, Bit Length 16, Unit µs Q0 (1
↔ 1 µs, pulse length is limited to a maximum of 500 µs)
-
Toggling following CAN Message from 0 to 1 applies the programmed pulses to the output
CAN-ID 10hex, Signal Name DEnable, Data Type Bit, Bit Start 0, Bit Length 1

The state diagram of the implemented SW is shown in Figure 10. The operator has with the led’s a simple
and fast way to determine the current state without using CAN communication, where much more detailed

Self Test Sequence
A self test is implemented in the uC software, which is performed at each power up cycle of the control
board. The Evaluation Kit will only start the normal operation, when the signals give reasonable values and
the test sequence was performed successfully. The sequence, which is illustrated in Figure 11, has four
major test procedures:
1. ADC value plausibility: Checks the supply voltages of the ADC
2. ADC value limits: Checks the offsets of the sensors and ADC values
3. Low side switching: Switches sequentially all low side IGBTs and checks currents and voltages
4. High side switching: Switches sequentially all high side IGBTs and checks currents and voltages

Figure 11 Overview of self test sequence with the four major test procedures.
The first part of the passive procedure checks the supply voltage of the uC and ADC. The ADC_1V95 signal
is connected to the uC supply status led, which has a quite stable voltage drop of 1.95V over wide supply
voltages. In case of drifts of the uC supply voltage, the ADC scaling of all sensors would not be correct. But
such a drift will be detected because in such cases the ADC_1V95 signal is also distorted and out of range.
After this test the test procedure waits for a DCL voltage higher than 20V. This is required because the later
switching tests makes no sense if the switch and phase voltages has always 0V Vce.

The passive tests are followed by switching tests of low side switches (see Figure 14) and high side switches
(see Figure 15). Each switch is turned-on and Vce voltage, low side phase current, DCL voltage, and gate
driver fault condition is checked for proper values. After this the switch is turned-off again.
After the test is successfully passed the default condition is than all low side switches turned-on. This
enables the supply of the high side gate drivers, which are implemented via bootstrap supply.
The same test procedure of the low side switches is than performed with the high-side switches, whereby the
corresponding low side switch is turned-off before.

Evaluation Kit CAN Terminal
5.1
Introduction and Feature Description
The Evaluation Kit has a CAN communication functionality, which can be used with all standard HighSpeed
CAN toolsets (1MBit/s). This CAN communication is isolated from the high voltage potentials. The CAN
Terminal option via the Infineon UConnect XC2xxxX hardware provides a low cost gateway from the
EASYKIT CAN port to a standard USB port (virtual COM).
With the CAN Terminal it is possible to control the EASYKIT in the CAN controlled mode with e.g. the
following functionality:

Adjust nominal motor parameters

Adjust motor speed

Monitor analog values and fault events from the EASYKIT

Monitor communication states

Perform single pulse tests
The main advantage for the customer is the low cost of this CAN Terminal solution compared to standard
CAN cards available on the market. No specific SW installations are required on the target PC only a
standard terminal program is required, which are available free of charge on the internet (e.g. Tera Term,
PUTTY,….). Please note that the update rate is limited compared to standard CAN communication
interfaces.

the mixed signal scope during the active switching part. The major events are numbered on the bottom of the
screen shoot. Please take note that the phase voltages during switch turn-off phases can have different
shapes depending on the connected load. However, when a switch is turned-on the Vce voltage of this

Short Circuit Tests
Short circuits can be considered as most critical events for an inverter. Two different types of short circuits
were tested with the Evaluation KIT. Short circuit I is a short circuit close to the power module (e.g. on the
power connectors) and thus has a low inductance. The short circuit II appears in the system if e.g. the motor
windings generate a short.
The following tests were performed at 25°C, where higher short circuit currents and faster switching
characteristics (voltage overshoot) is achieved compared to Tj=150°C.
6.2.1
Short Circuit I (low inductance)
The power terminal of the phase output was directly connected to the DCL+ terminal. A current probe was
inserted in the short circuit cable to measure the currents of this short circuit (IL). The equivalent circuit
during this test is shown in Figure 22.

Figure 23 shows the measured waveforms of the IGBT (see Vce and Vge) and the short circuit current (IL).
The IGBT turns-on at 0 us. After approx 0.4 us the current is high enough that the IGBT desatures (Vce
voltage rises to high values despite the IGBT is still turned on). This desaturation is detected quite fast in the
gate driving circuit, which turns-off the IGBT at approx 1.5us. The turn-off overvoltage with <100V is
relatively low. All measured values were within the specification of the F4-50R07W1E3_B11A power module.

IGBT Turn-off (450V, 100A, 25°C)
The Evaluation Kit does not use anly clamping circuits to limit Vce overshoots. Therefore, an IGBT turn-off
pulse at low temperature, max DCL voltage and collector current for switching operation has to be tested.
Figure 32 shows the measured waveforms of this IGBT turn-off event. The voltage did not exceed 550V. The
low current capability of the gate driving circuit and the unipolar supply had the disadvantage of higher
switching energies. However, this test at high DCL voltage and collector current shows that active clamping
measures to limit Vce voltage overshoots are not necessary in this Evaluation Kit.
Please take note that the overshoot characteristics strongly depends on many system parameters (PCB
layout, DCL-capacitor, gate driving circuits, temperature,…) . These results in the Evaluation Kit should not
be regarded as a general recommendation against active clamping measures.
