6.4 Auxiliary Power supply
Figure 14 depicts the schematic of the auxiliary power supply for the EVAL-M1-36-44A board. The circuit
includes the latest CoolSET 5 of Infineon and flyback toplogy, directly output 15V and 6V. V
CC
is connected to the
gate drivers inside the CIPOS™ IPM.
Figure 14 Power supply section of the EVAL-M1-36-44A evaluation board
The linear voltage regulator IFX1117ME V33 generates 3.3 V from 6 V power supply V
CC
. The 3.3 V power supply is
used in the inverter external overcurrent comparator circuit and over temperature hardware protection circuit.
Both V
CC
and 3.3 V are also present on the 20 pins iMOTION™ MADK-M1 interface connector J3 to power circuitry
on the control board.
