Analysis of Full Bridge Series Parallel Resonant Converter for Battery Chargers

Abstract:

This paper presents a novel application of full-bridge series parallel resonant converter (FBSPRC) for dc source and secondary battery interface. Secondary batteries has been widely used in the application of residential, industrial and commercial energy storage systems because of its low energy conversion loss, which enhances the systems overall efficiency. A series parallel loaded resonant converter (SPRC) which is a subset of DC-DC converter can be operated with either zero-voltage turn-on (above resonant frequency) or zero current turn off (below resonant frequency) to eliminate the turn on and turn-off losses of the semiconductor devices. This converter is widely used to achieve reduction in size of the passive components of the converter such as inductor, capacitor and transformers. Simulation results based on a 12V 45Ah battery charger are proposed to validate the analysis and to demonstrate the performance of the proposed approach. Satisfactory performance is obtained from the measured results. The simulation results validate the effectiveness of the chosen battery charger.
