摘　　要：为解决氢燃料电池输出特性软,输出电压低,动态响应慢等问题,采用移相全桥直流变换器作为前级功率变换器,构建变换器的状态空间模型,确定电流型变换器主电路参数和关键控制参数设计准则,完成氢燃料电池功率变换器的设计,搭建船舶氢储电力推进系统的仿真平台。仿真结果表明,该功率变换器实现了升压和稳压的功能,使氢燃料电池工作在最佳工作点。In order to solve such the problem of a hydrogen fuel cell as soft output characteristics,low output voltage and slow dynamic response,in this paper,a phase shift full bridge DC converter was supposed to use as the front-stage power converter,and the state space model of the converter was constructed.The design criteria of the main circuit parameters and key control parameters of the current-mode converter were firstly set,the construction of the converter was designed and the simulation platform of marine hydrogen storage power propulsion system was then built.It showed that the results from simulations verified the accuracy of the designed power converter,which improved and stabilized the output voltage of the hydrogen fuel cell while working at its best working point.
