Internal Equivalent Circuit and Input/Output Pins

Figure 3. Internal Block Diagram

Note:

1. Inverter high-side is composed of three IGBTs, freewheeling diodes, and one control IC for each IGBT.

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

3. Single drive IC has gate driver for six IGBTs and protection functions.

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