A study on Half bridge LLC resonant converter for battery charger on board

Abstract

In recent years, having the advantages of being small, low in cost and high in efficiency, Half bridge (HB) LLC resonant converter for power density and high efficiency is increasingly required in the battery charge application. The HB LLC resonant converters have been used for reducing the current and voltage stress and switching losses of the components. However, it is not suited for wide range of the voltage and output voltage due to the uneven voltage and current component's stresses. The HB LLC resonant for battery charge of on board is presented in this paper. The theoretical results are verified through an experimental prototype for battery charger on board.
