Internal Equivalent Circuit and Input/Output Pins

Note:

1. Inverter low-side is composed of three MOSFETs, and one control IC. It has gate driving and protection functions.

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

3. Inverter high-side is composed of three MOSFETs and three drive ICs for each MOSFET.
