The active-filter is one of the most efficient methods to improve power factor. However, this method has problems such as increasing switching loss and switching noise.
This paper describes a new power factor correction (PFC) converter called “Partial-switching PFC”, which achieves power factor rate of 99% only by generating a single pulse in the power line cycle with high efficiency and low total harmonic distortion. Its application to our air-conditioners is described at the end.
