Abstract

This paper considers the influence of small-series LC circuit on the input current-ripple which is inserted to Pulse-link DC-AC converter for fuel cells applications. Fuel cells have drawback about current-ripple because the chemical reaction time is much slower than commercial frequency. Therefore, in these applications, the input current-ripple reduction is essential factor in the DC-AC converter. Input current-ripple from fuel cells gives damage the fuel consumption and life time. The proposed pulse-link DC-AC converter has the advantage that small series LC circuit values achieve to reduce input current-ripple. Previous method which is shown before has drawback that inductance becomes large. The proposed method at this time uses only small inductance and capacitance value, so it can reduce the size of the unit. In this paper, it is analyzed the static characteristics of pulse-link DC-AC converter for fuel cells, and considers the input current-ripple reduction method used by small-series LC circuit.
