摘要：A Single power-conversion ac–dc converter with high power factor and high efficiency. The proposedconverter is derived by integrating a full-bridge diode rectifier and a series-resonant active-clamp dc–dc converter. Toobtain a high power factor without a power factor correction circuit, this paper proposes a novel control algorithm. Theproposed converter provides single power-conversion by using the novel control algorithm for both power factorcorrection and output control. Also, the active-clamp circuit clamps the surge voltage of switches and recycles theenergy stored in the leakage inductance of the transformer. Moreover, it provides zero-voltage turn-on switching of theswitches. Also, a series-resonant circuit of the output-voltage doubler removes the reverse-recovery problem of theoutput diodes. The proposed converter provides maximum power factor 0.995 and maximum efficiency of 95.1% at thefull load.
