3.1 Inverter section using CIPOS™ Maxi IPM
Figure 22 shows the inverter section of the EVAL-M1-IM818-A that is implemented using the CIPOS™ Maxi IPM.
The module includes an optimized SOI gate driver and three phase inverter with 1200 V TRENCHSTOP™ IGBTs
and Emitter Controlled diodes.
The three capacitors C10, C11 and C12 are used as bootstrap capacitors to provide the necessary floating
supply voltages VBS1, VBS2 and VBS3 respectively.
