摘要：

This of paper presents the design and implementation of a zero-voltage-transition power factor correction (PFC) converter which can achieve high power factor, low harmonic distortion, and high efficiency. Zero-voltage-transition soft-switching technique has been applied to reduce the switching losses of the auxiliary switching circuit for a single-phase sc-de converter with unit power factor. Its kW, 200 kH5 soft-switching single-phase PFC converter has operation principle and design equations have been given. A 2 been constructed. An efficiency of 94% at rated output has been measured. Experimental results show the developed design procedure for the ZVT soft-switching PFC converter can achieve unit power factor, high efficiency, and low EMI.
