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., 2008 13th International Power Electronics and Motion Control Conference, EPE-PEMC 2008; Poznan; 1 September 2008 through 3 September 2008, EPE-PEMC 2008, pp.148-153}, pages = {148--153}, publisher = {Institute of Electrical and Electronics Engineers}, title = {Consideration for input current-ripple of pulse-link DC-AC converter for fuel cells}, year = {2008} }
