1st Notes:
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.
