BM64374S-VA 600V IGBT Intelligent Power Modules

ROHM has introduced the BM6437x series that includes four new 600V IGBT Intelligent Power Modules (IPMs) that can deliver best-in-class low noise characteristics together with low loss ideal for power conversion in inverters. These new devices are suitable for compact industrial equipment, such as small capacity motors for robots, as well as home appliances including air conditioners and washing machines.

The new lineup of IGBT IPMs simultaneously reduces both radiation noise and power loss for achieving class-leading characteristics. Optimizing the built-in IGBT’s characteristics and soft recovery characteristics of the internal FRD (Fast Recovery Diode) allows the BM6437x series to decrease radiated noise by more than 6dB (at peak comparison) over standard products, making it possible to consider simplifying the noise filter that is typically required.

The new low-loss IGBTs used in these IPMs reduces power consumption over ROHM’s conventional IPM products by 6% (fc=15kHz), this achieves low loss and contributes to the reduction of various equipment power consumption. The new devices improve the built-in temperature monitoring function and offer ±2% accuracy (equivalent to 2°C). This helps in reducing the number of external parts that are used to maintain high accuracy.
