Abstract

This paper mentions the static characteristics of pulse-link DC-AC converter for fuel cells, and considers the input current-ripple reduction method. Fuel cells have weakness about current-ripple because the chemical reaction time is much slower than commercial frequency. Therefore, the input current-ripple reduction is essential factor in the DC-AC converter for fuel cells applications. Input current-ripple from fuel cells gives damage the fuel consumption and life time. The conventional DC-AC converter has large smoothing capacitor between boost converter stage and PWM converter stage, in order to reduce input current-ripple. That capacitor prevents from reduction the size of unit. Authors have proposed a novel topology called as pulse-link DC-AC converter. The pulselink DC-AC converter topology is no need to insert large capacitor. Furthermore, the series-connected LC circuit between two stages connected in parallel works as ripple canceling. This paper shows the mechanism of currentripple reduction.
