Abstract :
This paper considers input current-ripple reduction on Pulse-link DC-AC converter for fuel cells applications operated by zero-current-slope mode. 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. Input current-ripple is reduced when the inductor current flown at series LC circuit has zero-slopes in one switching period. At that time, small parameters values can be achieved.
