The power control technology has been combined with the microelectronic control technology,and the ship electric power control system has been developed to a very advanced level through various advanced rectification control technologies. Especially for high voltage power system development of PWM rectifier control technology,is playing a very prominent role. Based on the characteristic of low harmonic,low capacity storage and stable DC voltage control,this paper builds the topology model and control algorithm of high voltage power system of ship,and emphatically studies three-phase PWM rectifier in marine power system the design of. At last,the waveform output and harmonic suppression ability of the rectifier controller are simulated by Matlab.
