Single Power-conversion AC-DC Converter with High Power Factor
The Transactions of the Korean Institute of Power Electronics, 2014 This paper proposes a single power-conversion ac-dc converter with a dc-link capacitor-less and high power factor. The proposed converter is derived by integrating a full-bridge diode rectifier and a series-resonant active-clamp dc-dc converter. To obtain a high power factor without a power factor correction circuit, this paper proposes a suitable ...
