In order to solve the problem of fuel pollution , people abandone the diesel fuel for power generation of marine ,shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improving the environmentr. At the same time in order to achieve better control, in the thesis sliding mode control is applied to the closed loop system. The structures of main circuit, drive circuit and control system is described and the design of critical parameters are provided.
