White-Goods Power Modules Eyed By Joint Venture

Seoul, Korea and Neubiberg, Germany: LS Power Semitech, a joint venture company established by LS Industrial Systems and Infineon Technologies, will focus on the development, production, and marketing of moulded power modules for white-goods applications.

Infineon will deliver licenses to IP as well as technology and process information on its power-module family CIPOS (Control Integrated Power System). According to LS Power Semitech, it expects to begin mass production for CIPOS modules by January 2010.

The CIPOS modules incorporate a three-phase inverter power stage with a silicon-on-insulator gate driver, bootstrap diodes and capacitors, and auxiliary circuitry in an isolated package. Based on a combination of Infineon’s TRENCHSTOP IGBT and emitter-controlled diode technology, they eliminate as many as 23 discrete components compared to a design based on discrete components.
