This evaluation board was designed in addition to the module 1 adapter board MA3L120E12_EVAL or could be a complementary part for an existing customer driver solution. For more details about the 3-level topology, please refer to [1]. The board is available from Infineon in small quantities. The properties of this board are described in the design feature chapter of this document, whereas the remaining paragraphs provide information to enable the customers to copy, modify and qualify the design for production, according to their own specific requirements. Environmental conditions were considered in the design of the F3L2020E12-F-P_EVAL. Components qualified for a lead-free reflow soldering process were selected. The design was tested as described in this document but not qualified regarding manufacturing and operation over the whole operating temperature range or lifetime. The boards provided by Infineon are subject to functional testing only. Due to their purpose evaluation boards are not subject to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products. See Legal Disclaimer and Warnings for further restrictions on Infineon‟s warranty and liability.

The adapter board should be pressed to the EconoPACK 4 as described in the AN2010-06. F3L2020E12-F-P_EVAL MA3L120E12_EVAL F3L400R12PT4_B26 Figure 7: Driver board, adapter board and IGBT module of the 3-level evaluation kit 4.1 Power supply Four external power supplies for the IGBT driver ICs and external booster stages are needed. These -8V/+15V power supplies are applied to the F3L2020E12-F-P_EVAL board using connector X2 as depicted in Figure 8. The logic side has to be powered with +5V via the connector X1 also represented in Figure 8. Further pin assignments can be found in Table 6 and Table 7 on page 8. Figure 8: Principle diagram of the F3L2020E12-F-P_ EVAL The 1ED020I12-B2 IGBT driver IC monitors the supply voltage and activates the Under Voltage Lock Out (UVLO) as soon as the supply voltage drops below the UVLO reference value. 10 Evaluation Driver Board for EconoPACKTM 4 3-Level Modules 4.2 Application Note AN2013-04 V1.1 February 2014 Input stage The Evaluation Driver Board is designed for one leg of a 3-level IGBT configuration; therefore it is necessary to apply four separate PWM signals dedicated to each IGBT. Schematic details for a single IGBT driver are depicted in Figure 9. Figure 9: Schematic details of the input stage for a single IGBT driver. It is possible to choose positive or negative logic according to individual designs. For the use of IN+ as PWM input, the IN- pin can be used as enable signal pin. For the use of IN- pin as PWM input, the IN+ pin can be used as enable signal pin. If the power supply voltage of the logic side exceeds the power-up voltage VUVLOL1 and the power supply voltage of the high side exceeds the power-up voltage VUVLOH2, green RDY LEDs shown in Figure 10 for IGBT1 to IGBT4 are turned on. 4.3 Short circuit detection Short circuit is monitored individually by the four IGBT driver channels. Each of the four channels provides an independent fault signal; they share a common reset input. Failure handling of the high and low side IGBT has to be part of the superordinated control. When a short circuit occurs, the voltage increase across the IGBT is detected by the desaturation protection of the 1ED020I12-B2 and the IGBT is turned off. The fault is reported to the primary side of the driver as a low active signal. Red LEDs /FLT_T1 to /FLT_T4 as presented in Figure 10 are turned on to signalize the failure condition. The fault status remains active as long as there is no reset signal applied to the driver. The /FLT signal is active low. Figure 10: Positions of the status LEDs on F3L2020E12-F-P_EVAL 11 Application Note AN2013-04 Evaluation Driver Board for EconoPACKTM 4 3-Level Modules 4.4 V1.1 February 2014 Output stage The output stage of the F3L2020E12-F-P_EVAL as depicted in Figure 11 is prepared to be connected to the complementary MA3L120E12_EVAL evaluation module adapter. The module adapter is directly plugged to TM the 3-level EconoPACK 4 module as shown in Figure 7 on page 10. The MA3L120E12_EVAL evaluation board consists of an active booster stage to provide the necessary switching power, demanded by the IGBT module. Figure 11: Schematic details of the output stage for a single IGBT driver For further and more detailed information on the 1ED020I12-B2 please refer to the Infineon datasheet. 5 Paralleling The F3L2020E12-F-P_EVAL was designed to work with the evaluation adapter board MA3L120E12_EVAL as single unit as depicted in Figure 7 on page 10 or to allow the parallel connection of up to three modules, each equipped with one MA3L120E12_EVAL adapter board as represented in Figure 12. In case of paralleling, the driver board does not need to be plugged into the complementary adapter board. The connection from the driver to the adapter boards is done utilizing the connectors on the top side of the driver board as shown in Figure 13. Figure 12: Principle of parallel connection of three EconoPACK 12 TM 4 IGBT modules Evaluation Driver Board for EconoPACKTM 4 3-Level Modules Application Note AN2013-04 V1.1 February 2014 Figure 13 displays a parallel connection of three 3-level IGBT modules. In this case it is necessary to assure the same length of the gate wire between the driver and adapter boards to obtain the same run time of the gate signals for the three IGBTs. Star connection of the IGBTs reduces the cross flow in the emitter lines after the switching sequence. The F3L2020E12-F-P_EVAL driver board allows to switch up to three IGBTs in parallel.
