摘　　要：为减小风光发电系统体积和成本,设计了一种适用于风光发电系统的四端口DC/DC变换器,对变换器工作原理进行了分析,给出了控制器设计方法.该变换器的3个端口电压可通过分别调整各自占空比来控制,另外一个端口用来实现整个系统功率平衡.最后用Matlab软件进行了仿真.仿真结果证明了该变换器拓扑结构的可行性,验证了它控制3个能量端口的能力.该结构有一定应用价值.In order to reduce the volume and cost of the wind/PV generation system（WPGS）,this paper designs a four-port DC/DC converter for the WPGS,which involves analyzing the operating principles of the convertor and presenting the design method of the controller.In this design scheme,the three-port voltages can be controlled by adjusting each duty-cycle respectively,and the left port can be used for balancing the whole system’s power.Finally,by using Matlab software,simulation is performed,thus,showing the feasibility of the convertors’topology and verifying its capability of controlling three energy ports.And the topology is of a certain applicable value.
