Used in conjunction with the 2ED300E17-SFO evaluation adapter board and the 2ED300C17-S or -ST EiceDRIVER™ turns the adapter evaluation board into the Flexible driver Starter Kit displayed in Figure 1b. The Flexible Evaluation adapter board is dedicated to single module operation. In cases of IHM parallel switching, one 2ED300E17-SFO adapter board and one 2ED300C17-S driver is required for up to three modules paralleled, each equipped with one MA40xExx board. The MA40xExx module adapter boards are available from Infineon in small quantities. Functions and properties of these parts are described in the datasheet chapter of this document whereas the remaining paragraphs provide information intended to enable the customer to copy, modify and qualify the design for their own specific application. Environmental conditions were considered in the design of the MA40xExx. The requirements for leadfree reflow soldering have been considered when components were selected. However the design was only tested as described in this document but not qualified regarding manufacturing and operation over the whole operating ambient temperature range or lifetime. The boards provided by Infineon are subjected to functional testing only. Due to their purpose evaluation boards are not subjected to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Withdraw (PWD) as regular products.

Due to IGBT short circuit performance a maximum value of VGE ~15V is recommended Asymmetric power supply is also allowed e.g. -8V and +15V Input PWM voltage level should be selected according to the power supply voltage level. If an asymmetrical supply voltage of -8V/+15V is applied, the PWM signal should not exceed +15V and should not be lower than -8V 2.2 Key data All values given in the table below are typical values, measured at an ambient temperature of TA = 25 °C.

In that way necessary connections between module adapter and module itself are done correctly as shown in Figure 2. Figure 2 The MA400E12 correctly mounted on an IHM module PCB outline and relevant dimensions needed for better system integration are shown in Figure 3. Figure 3 Dimensions of the MA400E12/17 module adapter board The mechanical difference between MA400Exx and MA401Exx is the shifted position of the gate and emitter screw terminals according to the related IHM housing. 3 The AN2004-05: ‘Mounting process IHM modules’ is available on the Infineon website. 6 N 2010-03 2009 Application Note AN 2011-01 V1.1, February 2014 Module Adapter Board for IHM IGBT Modules 2.4 Pin assignment After the module adapter has been correctly mounted to the IHM module, all external electrical control signals are to be applied to connector X2 as shown on Figure 4 and listed in Table 2. If the MA40xExx is used in combination with the 2ED300E17-SFO, control signals required for module driving should be connected to the input Interface of the 2ED300E17-SFO as described within the AN2007-05. In that way no additional connections between module and IGBT driver are needed.

Figure 5 The MA40xExx with marked functions 3.2 Gate resistors Any MA40xExx is assembled and delivered without gate resistors as shown on Figure 5. The correct gate resistors have to be soldered by the customer according to the IGBT module used. In case the values of RGon and RGoff need to be different, the Diode D25 needs to be assembled to separately adjust the values of RGon and RGoff. 3.3 Gate signal amplifier4 While the IGBT switches on or off, high peaks of the gate current have to be delivered from the driver. Usually there is no technical problem when driving a single module. If one IGBT driver is used for modules connected in parallel, the driver’s amplifier has to provide the cumulated gate currents. This switching condition leads to the gate power loss being concentrated in one relatively small physical area and may result in thermal problems. The high peak currents also require a high current gain driver. Overcoming gain limitation becomes possible when the module adapter includes a dedicated gate signal amplifier. The schematic in Figure 6 shows, that the MA40xExx has an emitter follower or booster stage already implemented. Thanks to six complementary bipolar transistors connected in parallel the minimum gain @IG=40A is not smaller than 100 based on ZXTN2010Z and ZXTP2012Z bipolar transistors datasheets. 4 More information can be found in EPE07 paper ‘Benefits of System-oriented Module Design for High Power Inverters’, or PELINCEC2005 paper ‘Dynamic Voltage Rise Control – the Most Efficient Way to Control Turn-off Switching Behavior of IGBT Transistors’. 8 N 2010-03 2009 Application Note AN 2011-01 V1.1, February 2014 Having a booster stage comes with the benefit to get excellent control on the gate-emitter voltage of any IHM-type module and enables a simplified design in paralleling IGBT-modules. Figure 6 Booster stage of the MA40xExx 3.4 VCE monitoring for short circuit detection If the IGBT conducts a current a few times higher than the nominal value, the transistor desaturates and the voltage across the device increases. This behavior can be used for short circuit detection and turn-off of the IGBT. The short circuit needs to be detected and the IGBT has to be turned off without exceeding its maximum blocking voltage, within 10µs. When the MA40xExx is connected to a 2ED300E17-SFO the RSSD resistors that define the Soft Shut Down function must be chosen correctly in order to ensure proper short circuit protection. The detailed procedure is described in AN2007-05 chapter 3.5. Figure 7a shows the short circuit behavior of FZ1600R17HP4_B2 IHMB modules where short circuit protection on the 2ED300E17-SFO was disabled. To protect the device from destruction in this test, the gate-pulse applied to turn on had a duration of 10µs. High dIC/dt during turn-off creates a large overvoltage spike which is limited by active clamping. Figure 7b depicts how soft shut-down with a properly selected RSSD limits the short circuit time to less than 10µs and additionally decreases the collector current slew rate during turn-off.

The standard approach to active clamping is to use a chain of avalanche diodes connected between the auxiliary collector and the gate of an IGBT module. When the CollectorEmitter voltage exceeds the diodes breakdown voltage the diodes current sums up with the current from the driver output. Due to the now increased gate-emitter voltage the transistor is held in an active mode and the turn off process is prolonged. The dIC/dt slows down which results in a limited voltage overshoot. Avalanche diodes conduct high peak currents during the time period in which the clamping is actively limiting the overvoltage. Overvoltage protection within the MA40xExx is based on an improved variant of the active clamping as described above. The clamping diodes are connected directly to the IGBT’s gate but also to the input of the amplifier located on the MA40xExx. Therefore the major amount of current for recharging the gate is derived from the gate driver power supply instead of being drained through the clamping diodes. This provides more consistent clamping voltage due to operating the clamping diodes at a lower current level and furthermore enables the clamping circuit to be designed independently from the selected external gate resistor. Figure 8 below displays the switching behavior of a FZ1600R17HP4 IGBT module at 900V DC voltage. During the turn off sequence, the gate current IG from the booster, the current ICLAMP through the active clamping diodes, the gate voltage VGE, the IGBT collector emitter voltage VCE and the IGBT current IC have been monitored. At the nominal current in figure 8a, the magnitude of the IGBT collector emitter voltage does not exceed the breakdown voltage of the avalanche diodes. The current through the diodes remains close to zero. At increased current levels, switching leads to an overshoot exceeding the avalanche diode breakdown voltage. The diodes now conduct high peak currents as marked in region A. This current leads to recharging of the gate by activating the booster stage and turning on the gate-voltage again. The IGBT is hold in linear operation with decreasing collector current. As a consequence, the voltage across the device is reduced. As soon as the overvoltage gets down to the desired level, the clamping diodes return to blocking state turning off the gate as marked in region B. The turn-off procedure of the IGBT continues as desired.

These power losses in the gate resistors depend on the IGBT gate charge, gate voltage level and on the switching frequency of the IGBT. Due to the power losses in the external gate resistors heat will be generated, which leads to an increase of the PCB temperature in the neighborhood of these resistors. This temperature must not be higher than the operating temperature allowed for the PCB in use, i.e. 105°C for a standard FR4 material. 10 Application Note AN 2011-01 V1.1, February 2014 Module Adapter Board for IHM IGBT Modules The calculation of the power losses in the gate resistors can be done by utilizing equation 1: Pdis P( REXT ) P( RINT ) Vout f s QG (1) The parameters used describe: Pdis the power dissipated [W], ΔVout the voltage step at the driver output [V] fs the switching frequency [Hz], QG the IGBT gate charge for the given gate voltage range as given in the datasheet The complete gate resistor consists of the internal gate resistor R GINT and an external gate resistor RGEXT mounted on the MA40xE12/E17. Due to that, a part of the according losses will be dissipated directly through the DCB into the base plate, whereas the other part of the power losses will be dissipated externally to the ambient air and into the PCB. The ratio of the losses dissipated internally P(RGINT) and externally P(RGEXT) corresponds directly to the ratio of the mentioned resistors RGINT and RGEXT. Figure 9 presents a measurement result showing the external gate resistor temperature as function of the losses generated in that resistor. It can be read from the graph, that for the ambient temperature of 25°C and the base plate temperature of 125°C the maximum temperature of the PCB reaches 105°C with power losses in RGEXT equal to 1.1W. In that case the limiting factor for the switching frequency is not the DC/DC converter with its available power of 4W per channel. Operation is limited due to the maximum temperature of the PCB. Higher switching frequency can only be obtained by utilizing a PCB with higher melting temperature or resistors with improved thermal transfer to ambient.

In this case all the IHM modules have dedicated MA40xExx boards connected to the 2ED300E17-SFO adapter board. It must be noted that RSSD in every case should be selected according to AN2007-05 chapter 3.5.
