4.2 Inverter section using CIPOS ™ Mini IPM
The inverter section is also implemented using the CIPOS ™ Mini IPM as sketched in Figure 18. The inverter
section of the IPM module includes an optimized SOI gate driver and a three-phase inverter consisting of
TRENCHSTOP ™ IGBTs and anti-parallel diodes.
The three pairs of capacitors C14 and C15, C16 and C17, C22 and C23 are used as bootstrap capacitors to
provide the necessary floating supply voltages V
BS1
, V
BS2
and V
BS3,
respectively.
