Abstract
This paper proposes the novel boost input type resonant AC/DC converter. Since the proposed converter is single stage topology, it controls both of the input power factor and the output voltage at the same time, and resultingly obtains the high power factor of 99% with average current mode pulse width modulation. Especially, to accomplish the zero voltage switching, the resonance between the leakage inductance and external capacitor is used. For the theoretical consideration of the proposed converter, the six operation modes divided by means of current path are discussed, and the resonance characteristics in steady state are analyzed. To verify the validity of the proposed converter, a 200[W]($120[V_AC],\; 출력\; 48[V_DC],\; 4[A]$prototype converter was built and its experimental results were presented in this paper.
