This paper deals with a new implementation of a VoltageDoubler SingleStage Power Factor Corrector OS’PFC). This new VD-S‘PFC provides a reduction (by half) of the total voltage drop due to diodes conducting at the same time from the tine input to the energy-storage capacitors. Moreover, the size of the additional inductors used to shape the line current is dramatically reduced due to the fact that these inductors form part of an additional output of the main dc-to-dc converter, which is based on a full-wave rectifier and, therefore, these inductors are operating at hvice the converter switching frequency and with a higher duty cycle than in the case of being based on a half-wave rectifier, as in some previous cases. The experimeutal results show that both inductors can be hnllt into two E20 cores for a 100 W, 62 Vdc prototype. The voltage across the series connection of both energy-storage capacitors is lower than 5OOV and the total efficiency ofthis prototype is 92-90%.
