Infineon’s CIPOS Micro IPMs Boast High Efficiency Operation

April 2, 2019 Alix Paultre

Infineon Technologies’ CIPOS Micro IM231 family of 600V-rated intelligent power modules (IPM) features the motor drive TRENCHSTOP6 IGBT and optimized switching characteristics for higher efficiency and low EMI. With 2 kV, this IPM offers the highest UL1557-certified isolation voltage in its class. The series comprises 4 A (IM231-M6S1B, IM231-M6T2B) and 6 A (IM231-L6S1B, IM231-L6T2B) offerings. The IPM can be implemented with or without heatsink, pushing power up to 450 W.

Qualified for harsh humid environments, passing 1,000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing, the energy-efficient IPM suits power appliance motor drives particularly in circulator hydronic pumps, drain pumps for washing machines, dishwashers, and kitchen hoods. Offered in both through-hole and surface-mount form factors, the devices have a built-in UL-certified NTC thermistor, anti-shoot through, and overcurrent protection and fault reporting features.
