摘　　要：在输入电压高、输出电流大的DC/DC变换器场合可以采用一种输入串联、输出并联(ISOP)的拓扑。ISOP拓扑的关键问题是输入电容的动态均压。文章分析了输入串联、输出并联的双全桥变换器输入不均压、输出不均流的原因;同时,在理论分析的基础上,应用Simulink软件对一种交错控制的变换器控制策略进行了建模和仿真,仿真结果验证了该控制策略的有效性。An input-series-output-parallel（ISOP） circuit topology is used for the DC/DC conversion with high input voltage and high output current.The key issue of ISOP is the dynamic voltage sharing of input capacitors.It points out the reason of the input voltage unsharing and output current unsharing for dual full-bridge converter of ISOP.At the same time,on the basis of theoretical analysis,it modeled and simulated an interleaving control by Simulink.The results verified the effectiveness of the proposed method.
