Intelligent power modules aim at electric and hybrid vehicles

April 22, 2013 // By Christoph Hammerschmidt
Mitsubishi Electric Corporation has developed a series of large-capacity intelligent power modules (IPMs) mainly for application in electric and hybrid vehicles. Power modules for automobiles offer higher reliability than industrial-use modules due to extremely high standards for vehicle safety.

Features of Sample Products

1) Large-capacity IPM for automotive motors

- J-Series TYPE+B series offers a choice of 600V/800A and 1,200V/500A models.
- Larger current capacity than existing TYPE-B models, but with same footprint area. - Built-in power supplies for IGBT drive and logic circuits.

2) All-in-one IPM for automotive motors

- Low-loss 3-phase CSTBTTM inverter configuration with built-in control-power supply circuit, optimized IGBT drive & protection circuit, and high-grade isolation photo-couplers.

- High-accuracy analog temperature monitor for chip center.

Common Features of All J-series IPMs

-IGBT drive & Protection (short-circuit protection, control-power-supply under-voltage protection, over-temperature protection and fault signaling output).

- Isolation with photo-couplers.
- High-accuracy analog temperature output function monitors chip center.
- High-accuracy analog power-supply voltage output function monitors inverter DC-link voltage (optional). - IPM enabling ready-signal input for fail-safe operation.
- Vibration-resistant connectors for reliable interface with customer designs.

Environmental awareness

- J-series TYPE+B is compliant with the European Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS).

Sample shipments of two J-Series IPM (TYPE+B) models will start in August; mass production is expected to begin in 2014. The new modules will be exhibited at the PCIM trade fair in Nuremberg, Germany on May 14-16.
