Design and Implementation of LLC Resonant Converter for Photovoltaic Battery Charging Application

Abstract:

Photovoltaic power conditioning system (PVPCS) requires a high efficiency dc-dc converterstage capable of wide input voltage regulation and have the ease of maximum power point implementation for both stand alone photovoltaic system and grid-connected system. Galvanic isolation at the dc-dc stage can replace the isolation needed in the inverter stage and thus reduce the sizeof isolation transformer and increases overall system efficiency. This paper presents detailed analysis,design and implementation of a LLC resonant converter for photovoltaic battery charging application.The LLC resonant converter operate with zero voltage switching (ZVS) turn on and low current turnoff thus reducing switching losses. The experimental results are given to validate the operation andperformance of the converter.
