Air Conditioners
Partial Switching Power Factor Correction Module
by Ki-Young Jang, Yo-Chan Son, Man-Kee Kim, Sung-Il Yong, and Bum-Seok Suh, Fairchild Semiconductor
This paper introduces an integrated power module for a partial switching power factor correction circuit (PSP) used in air-conditioning systems. The proposed module incorporates two insulated gate bipolar transistors (IGBTs) and rectifier diodes, along with a gate-driving low-voltage integrated circuit (LVIC) and a thermistor for temperature monitoring, all of which are integrated into a direct-bonded-copper (DBC) based transfer-molded package. It is intended for use in inverter systems of low-power air-conditioners and is expected to provide compactness, reliability, and electrical and thermal performance.
