IGBT is added to IPM to increase power density

The CIPOS Micro IM231 series is a family of 600V IPMs that are qualified for harsh humid environments. They pass 1000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing and are suitable for power appliance motor drives in circulator hydronic pumps, drain pumps for washing machines, dishwashers, and kitchen hoods. They can also be used in air-conditioning fans, refrigerator compressors, and motorised blinds.

The IPMs have the company’s latest motor drive TrenchStop 6 IGBT and switching characteristics for higher efficiency and low EMI. They are claimed to have the highest UL1557-certified isolation voltage in their class, at 2kV.

The family includes  IM231-M6S1B, IM231-M6T2B (4A) and IM231-L6S1B, IM231-L6T2B (6A) models. They are available in through hole and surface mount form factors and have UL certified NTC thermistor, anti-shoot through and accurate over current protection and fault reporting features. The IPM can be implemented in applications with or without heatsink, pushing power up to 450W.

Anti-shoot-through prevents spurious simultaneous turn on of high and low side IGBTs caused by malfunction of the microcontroller or external noise. Integrated current protection has an accuracy of ±5%.

The IPMs can be used in multiple markets ranging from 100 to 230V AC using the same IPM package and identical PCB design to speed time-to-market.

This supports an easy design-in, leading to fast time to market.
