6.2 Inverter section using CIPOS™ Nano IPM
The inverter section is implemented using the CIPOS™ as displayed in Figure 12. The module includes six power
MOSFETs and three half bridge gate drivers.
The three capacitors C71, C72 and C73 are used as bootstrap capacitors to provide the necessary floating
supply voltages V
BS1
, V
BS2
and V
BS3
respectively.
