This paper introduced a high performance single stage soft-switching AC/DC converter. The introduced soft-switching AC/DC converter uses four switches full-bridge circuit construct to achieve the input power factor correction and the output DC voltage regulation. The introduced soft-switching AC/DC converter adopts interleaved operation mode in ac input side to reduce the input current harmonic and increase the supply power level. Moreover, the introduced soft-switching AC/DC converter can get soft-switching function on its main power switches without soft-switching auxiliary circuit. Thus, the cost of circuit in low. A simple phase-shift control strategy is used to synthesize a suitable low harmonics sinusoidal waveform for the ac input current and achieve well dynamic regulation. A design example of 1000W high performance DC power supply system is examined to assess its performance.
