Power Factor Correction Circuit For Inverter Air-Conditioner Using A Parallel Drive Method

병렬구동 방식을 이용한 인버터 에어컨용 역률제어회로

In this paper, the power factor correction circuit using a parallel drive method is proposed so that the high power inverter air-conditioner with 3[ph] compressor motor may obtain the cost down and the improved performance. The adequate design procedures are presented to reduce the material costs by eliminating the power factor improving LC filter and derating output capacitor and inverter switches. Using the determined components, the prototype circuit with 6[kW] power consumption is built and tested to verify the operation of the proposed circuit.
