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...
Based on the conventional forward converter, the transformer's magnetizing inductance is made small, and a reset winding of the transformer is moved to the secondary side, and furthermore, the anode terminal of the freewheeling diode is connected at a different point. Then a novel topology of DC-DC converter is proposed, and its power efficiency is predicted to be improved. This converter has both...
This paper presents the optimum design of an RC snubber to suppress the surge voltage across the transistor in a switching regulator with two-winding reactor. Analyzing the surge voltage across the transistor with an RC snubber by means of high-frequency equivalent circuits, we obtain the third-order characteristic equation. This third-order equation is analyzed by the aid of the root locus method...
