Internal Equivalent Circuit and Input/Output Pins

Figure 3. Internal Block Diagram

Notes:

1. Inverter low-side is composed of three IGBTs, freewheeling diodes for each IGBT, and one control IC. It has gate drive 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 IGBTs, freewheeling diodes, and three drive ICs for each IGBT.
