摘要
传统的双向DC-DC拓扑结构具有电压、电流应力大、响应速度慢的问题.针对这一问题提出三相交错并联双向DC-DC变换器的拓扑结构,采用PI滑模变结构控制方案;外环用PI控制方案,实现自动跟踪参考目标电压的目的,内环采用滑模变结构控制方案,并利用等效控制的方法使变换器在恒定的开关频率下工作,实现了各并联电路电感电流的均流.Matlab Simulink仿真结果表明,该控制策略具有响应速度快、鲁棒性强的优点.
Traditional bi-directional DC-DC topologies are voltage and current stress,the problem of slow response.In order to solve this problem put forward three phasealternatingparallel bi-directional DC-DC converter topology,uses the PI sliding mode variable structure control scheme;Outer ring with PI control scheme,the purpose of achieving automatic tracking the reference voltage,the inner ring using sliding mode variable structure control scheme,and using the method of equivalent control converter work under constant switch frequency,implements the parallel circuit inductance current flow.Through the Matlab Simulink simulation results show that the control strategy has the advantage of fast response speed,strong robustness.
