Note
1. Inverter low-side ( (1) – (12) pins) 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 ( (13) – (17) pins) is composed of two inverter dc-link input terminals and three inverter output terminals.
3. Inverter high-side ( (18) – (30) pins) is composed of three normal-IGBTs including freewheeling diodes and three drive ICs for each IGBT.
Thermal interference is an important factor that must be eliminated in PCB design. Assuming that components generate a certain degree of heat during operation, especially the heat generated by high-po...
