High-frequency IGBTs suit automotive power supply applications

International Rectifier (IR) announces a new 600-V automotive grade IGBT platform, COOLiRIGBT for use in a wide range of fast switching applications for electric (EV) and hybrid electric vehicles (HEV) including onboard dc-dc converters, motor drives, and battery chargers.

The new Gen. 1 COOLiRIGBT devices are capable of operating at the same fast switching speeds as MOSFETs, while offering higher efficiency at high current levels. The first generation COOLiRIGBT devices cover a broad current range and offer a minimum short circuit rating of 5μs, low Vce(on) and positive Vce(on) temperature coefficient. Additional features common to the family include square reverse bias safe operating area (SRBSOA) and maximum junction temperature of 175° C. COOLiRIGBT also provides designers with the flexibility of selecting a diode with optimized performance for the application.

The AUIRGC655A1N0 is optimized for main electric and hybrid vehicle inverters and large motor drives, while the AUIRGC65A20N0 and AUIRGC65G20N0 are targeted for power supply and high switching frequency applications. In addition to offering a higher maximum junction temperature and hard switching up to 200 kHz, the two devices deliver improved performance of higher currents due to lower conduction losses and enhanced efficiency when used in resonant Zero Current Switching (ZCS) topologies.

IR’s automotive IGBTs are subject to dynamic and static part average testing combined with 100% automated wafer level visual inspection. The new devices are all environmentally friendly and assembled with lead-free and RoHS compliant materials.
