This paper proposes an immediate double-frequencyripple current command in a single phase high power fuel cell converter which can easily accomplish low frequency ripple free input current without using big electrolytic capacitors.In this proposed technique the content of ripples in present is actually reduced with no necessity of additional switching devices. A fuel cell power system which has a dc-acinverter tends to bring an ac ripple up at two times the output frequency. Such a ripple present could reduce feedback fuel celllifespan an innovative power control strategy is actually suggested to add a present control loop in the dc dc converter for ripple reduction. get rid of the double frequency ripple present disturbance lead by the single phase inverter load an In order to an In order tofuzzy controller and proportional-resonant controller is actually put together to complete an additional superior control gain at designed resonant frequency. This can reduce both size and price of the system. The system is created and simulated usingMATLAB/ Simulink Software.

Current-fed three-phase dc–dc converter, direct double-frequency ripple current control, electrolyticcapacitor free, fuel cell, zero voltage switching (ZVS).
