Interleaved Boost Converter with Boost-Type Snubber for PV Power System

Abstract:

This paper presents an interleaved boost converter with boost-type snubber for PV system. Paralleled converters working in interleaving manner are adopted to eliminate the pulsating current and increase powering capacity. Boost-type snubber is utilized for soft-switching of the power transistor to reduce switching losses. By switch integration, one boost-type snubber can be shared by N phases of boost converter to effectively reduce component counts and costs. The improved supply characteristics and conversion efficiency make it suitable for charging applications. A prototype for battery charger has been implemented to prove the feasibility of the proposed topology.
