Internal Equivalent Circuit and Input/Output Pins

Note:

1) Inverter low-side is composed of three sense-IGBTs including freewheeling diodes for each IGBT and one control IC which has gate driving, current sensing and

protection functions.

2) Inverter power side is composed of four inverter dc-link input pins and three inverter output pins.

3) Inverter high-side is composed of three normal-IGBTs including freewheeling diodes and three drive ICs for each IGBT.
