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 examines the effect of input current-ripple reduction on Pulse-link DC-AC converter for fuel cells applications. For reducing the input current-ripple, series LC circuit has been connected in parallel at the Pulse-link DC-AC converter. The input current-ripple characteristics have two main domains with combination of series LC parameters. The current-ripple level depends on inductance values...
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...
