Abstract: The on-board charger is a charging device installed on electric vehicle, and its main function is to charge the on-board power battery. It is an important component of pure electric vehicle and plug-in hybrid electric vehicle, and making it have efficient performance indicators is a key research direction for various vehicle companies and component suppliers. The article focuses on a certain 3.3 kW car charger. By using the fundamental wave equivalent method to create a model, the transfer function is derived, and appropriate resonance parameters are selected based on the transfer function to improve its conversion efficiency. The experimental results show that the scheme has good performance and reliability, and can meet the charging needs of electric vehicle. The research results of this article are of great significance for promoting the development and popularization of electric vehicle.
