In fuel cells applications, current-ripple reduction is essential for conversion efficiency and life span. This paper analyzes the pulse-link DC-AC converter for fuel cells applications operated in zero-current-slope mode. As the result, in zero-current-slope operation mode, input-current-ripple is reduced. Furthermore, in this operation mode, the parameters of series LC circuit which is worked as...
This paper mentions the input current ripple reduction method of the Pulse-link DC-AC Converter for Fuel Cells. The conventional DC-AC converter for fuel cells is interpolated large capacitor between boost converter stage and PWM inverter stage. That capacitor disturbs the size reduction of this unit. To overcome this problem, authors have proposed a novel topology called as Pulse-link DC-AC converter...
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...
This paper considers that the mechanism of input current-ripple on pulse-link DC-AC converter for fuel cells. And the reduction methods are shown. In general, fuel cells are weak about current ripple. The current-ripple damages to the fuel capacity and life span because the chemical reaction time when generates electricity is much slower than commercial frequency. Therefore, the input current-ripple...
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...
Authors have proposed a novel DC-AC converter topology for fuel cells, which includes a novel method for the reduction of input current-ripple. In general, the current- ripple in fuel cells give s damage to the fuel cell consumption and life span because the chemical reaction time is much slower than the commercial power source frequency. Therefore, the input current-ripple should be reduced in the...
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...
