Integrated power modules have higher current ratings

6 April 2005 Power Electronics / Power Management

A set of 600 V, 16 A and 20 A integrated power modules (IPMs) has been introduced by International Rectifier, expanding its iMOTION integrated design platform. The new IPMs simplify the design of compact, high-performance variable-speed motion control power stages for airconditioners and commercial freezers, for example.

Designed specifically for 85 V to 253 V a.c. variable speed motor drives for energy efficient appliances, they integrate IR's proprietary high voltage integrated circuit (HVIC) with a three-phase inverter power stage. The 16 A device addresses the 750 W to 1,2 kW power range while the 20 A devices can accommodate 750 W to 2,2 kW.

All of the new IPMs are packaged in efficient, single in-line packages (SIP) with improved thermal characteristics.
