A new ripple current reduction method of fuel cell output for boost converter, which has no additional active filter, is proposed. In proposed method, the converter controls the ripple current as well as output voltage of the converter. A current ripple reduction pass of the control loop, which has little affection of controller, has added for fast output voltage dynamics. The dynamics of the output voltage designed very fast with only about 16 ms, which is as low as two periods of 120 Hz current ripple of inverter load. The above<br/>
characteristics are verified by PSIM simulation.
