摘　　要：为满足加装超级电容的电动汽车对DC/DC变换器低压大电流、动态响应快的要求,选择了一种交错并联双向DC/DC变换器拓扑,其具有开关管电压应力低、输入电压与输出电压具有较大的变换比、输入电流与输出电流波纹小等优点.针对电动车在不同情形下系统的控制目标,设计了相应的控制器,并在Matlab/Simulink环境下构建控制器的仿真模型,对其性能进行分析.结果表明所选的拓扑结构及控制方法很好地达到了设计要求.To meet the need of super capacitor electric vehicle responding to DC/DC converter with low voltage and high current,fast dynamic response,we select an interleaved bi-directional DC/DC converter topology with switch voltage stress,low input voltage and output voltage,which has a larger transformation ratio,input current and output current ripple,etc..According to the control target of electric vehicles in different circumstances of the system,the corresponding controller is designed.Finally,the simulation model of converter control circuit in the Matlab/Simulink environment,and its performance are analyzed.The results show that the topological structure and control method selected well meet the design requirements.
