AB - 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%.
