摘　　要：为满足电动汽车对充电机大电流输出、高功率密度及高性价比的要求,本文应用静态均流、动态均流对IGBT(Insulated Gate Bipolar Transistor)并联技术进行理论分析。结合移相全桥技术,设计了一款3只IGBT并联使用的大电流输出智能充电机。实验及实际应用情况表明,该设计运行可靠、各项指标满足要求,且成本较低,具有很强的市场竞争力。To meet the electric vehicle charger current output, high power density and high performance requirements. In this paper, the theoretical analysis of static current sharing and dynamic current sharing for IGBT（Insulated Gate Bipolar Transistor） paralleling are presented. Designed a large current output smart charger of three IGBTs paralleling with phase-shift full bridge technology. The reliable operation, the indicators meet the actual requirements and low cost are verified by the experiments and practical application, and have very strong market competitiveness.
