Interleaved Soft-Switching Converter with L-C-D Snubber for Reflex Charger

Abstract:

This paper presents a Reflex charger realized by N sets of interleaved soft-switching converters with L-C-D snubbers. The interleaved converters used for implementing the Reflex charging technique can be interleaved boost, interleaved buck-boost, and interleaved sepic converters. The use of the L-C-D snubber in each set of interleaved converter is to reduce turn-off switching losses, hence, to achieve higher conversion efficiencies of the interleaved converters and to extend the lifetime of rechargeable batteries. A prototype of Reflex charger with four sets of interleaved buck-boost con-verters is implemented for charging lead acid batteries of 12V. Experimental results show that the proposed circuit structure can generate the required positive/negative pulses for the Reflex charging.
