BM64 600 V IGBT Intelligent Power Modules (IPMs)

ROHM has developed four 600 V IGBT intelligent power modules (IPMs) that comprise the BM64 series which deliver low noise characteristics together with low loss ideal for power conversion in inverters. Optimizing the built-in IGBT's characteristics and soft recovery characteristics of the internal FRD reduces radiated noise by over 6 dB (at peak comparison) vs standard products. This makes it possible to consider simplifying the noise filter that is typically required. At the same time, incorporating ROHM's IGBT reduces power loss by 6% (f_C = 15 kHz) compared with conventional products by decreasing both conduction and switching losses. Dramatically improved temperature monitoring accuracy makes it possible to consider eliminating an external thermistor. The result is a performance that delivers lower power consumption in a variety of equipment.
