Abstract
This paper proposes a novel soft-switching interleaved boost converter composed of two shunted elementary PFC boost conversion units and an auxiliary inductor. This converter is able to turn on both the active power switches at zero voltage to reduce their switching losses and evidently raise the conversion efficiency and power factor. Since the two parallel-operated elementary boost units are identical, operation analysis and design for the converter module becomes quite simple. A laboratory test circuit is built, and the circuit operation shows satisfactory agreement with the theoretical analysis. The performance of the proposed PFC rectifier was evaluated on an experimental 300[W] PFC prototype.
