A novel high - power pollution - free smps is presented in this paper, which accomplishes simultaneously the goal of soft - switching pwm, the input / output isolation, the output voltage regulation and three - phase pfc with a single - stage power processor and simple pseudo - phase - shift control circuit. therefore, compared with the normal two - stage system, the single - stage power supply has simpler structure, lower cost, higher efficiency and easier to control. the proposed smps can be used in the three - phase power system, and can output high power over kw - order and input / output ( i / o ) isolation dc power supply
