iMOTION™ Modular Application Design Kit

Hardware description of EVAL-M3-IM564

With the MADK output power increasing, the IPM DCB PFC test point and IGBT test point temperature are

monitored. The final test results are shown in Figure 31.

Auxiliary power supply

Figure 32 depicts the schematic of the auxiliary power supply for the EVAL-M3-IM564 board. The circuit includes

an ICE5QR4770AG that is used to generate 15 V and 6 V through the QR flyback topology from the DC bus.

Figure 32 Power supply section of the EVAL-M3-IM564 evaluation board

The linear voltage regulator IFX1117ME V33 generates 3.3 V from a 6 V power supply. The 3.3 V power supply is

used in the PFC overcurrent comparator circuit and overtemperature hardware protection circuit. Both 15 V

and 3.3 V are also present on the 30-pin iMOTION™ MADK-M3 interface connector J3 to power circuitry on the

control board.
