【Abstract】 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.更多还原
