EV and HEV drive circuits targeted by intelligent power modules
Mitsubishi Electric’s IPM announcement comprises, firstly, Large-capacity IPMs for automotive motors. the J-Series TYPE+B series offers a choice of 600V/800A and 1,200V/500A models, with larger current capacity than existing TYPE-B models, but with same footprint area. They have uilt-in power supplies for IGBT drive and logic circuits.
A second product category is an all-in-one IPM for automotive motors, gfeaturing low-loss 3-phase CSTBTTM inverter configuration with built-in control-power supply circuit, optimised IGBT drive and protection circuit, and high-grade isolation photo-couplers. High-accuracy analogue temperature monitors protect the semiconductor chips. for chip center.
All of the J-series IPMs have short-circuit protection, control-power-supply under-voltage protection, over-temperature protection and fault signaling output; isolation by photo-couplers; high-accuracy analogue chip temperature monitoring. A high-accuracy analogue power-supply voltage output function monitors inverter DC-link voltage, and there is an IPM enabling ready-signal input for fail-safe operation. Vibration-resistant connectors ensure reliable interface with customers’ designs.
