Abstract:
There are two proposed converters in this paper, one of which is inverting while the other is non-inverting.. Both converters work on the principle of resonance and the active elements operate under soft-switching conditions. The topology is similar to that of SEPIC converter, but the operation is different. In fact, inductors and Capacitor create coupling networks. The circuit has been simulated using MATLAB Simu-link. Simulation results are verified.

Keywords: Resonant converter, soft-switching, step-down/upconverter, zero current switching (ZCS)
