| Abstract: | As the power switches of traditional PFC(Power Factor Correction) converter working in hard-switching mode has high voltage stress,combined with the techniques of phase-shifted full-bridge and active-clamping,a PFC converter based on traditional Boost circuit is proposed,which realizes the power factor correction and DC/DC conversion by single stage circuit.By the active-clamping circuit parallel to the bridge and suitable control strategy,the voltage spike induced during the commutation by the leakage indu... |
