Abstract

This paper proposes a novel DC-AC converter topology for fuel cells applications, and mentions the reduction methods of input current-ripple. Fuel cells are generated electricity by chemical reaction. Chemical reaction time is much slower than commercial frequency. So, input current-ripple may damage the fuel consumption and life span. The conventional DC-AC converter for fuel cells has large capacitor between boost converter stage and PWM inverter stage, in order to reduce the input current-ripple. That capacitor prevent from reducing the size of its unit. The proposed DC-AC converter, called pulse-link DC-AC converter provides boosted-voltage pulse directly to PWM inverter. This topology is no need to insert large capacitor. Furthermore, the series LC circuit which is inserted on proposed topology works as ripple canceling. This paper shows the mechanism of current-ripple reduction. Moreover, active input current-ripple reduction method is shown.
