UNIVERSAL SINGLE-STAGE POWER CONVERTER WITH PFC CAPABILITY

摘要

A switched-mode power converter power converter, in one preferred embodiment with eight switches connected between three ports and an inductive element, with a donor (charging) port, a receptor port (load) and donor/receptor port (storage) operated so that energy may be switch between any of the ports regardless of the polarity and magnitude of the inductor current at the beginning of a chopping cycle. In one embodiment of the invention power conversion and power factor correction are accomplished in a single stage.
