چکیده :

This paper introduces a new non-isolated dual-input high step-up DC-DC converter utilizing a coupled inductor design. The proposed converter ensures soft switching operation for all power switches and diodes, significantly reducing switching and reverse recovery losses. Additionally, the converter features continuous input currents, with reduced ripple achieved through the series configuration of input inductors during switch-off intervals. To validate the effectiveness and advantages of the design, a 200 W prototype with a 340 V output voltage was simulated at a 50 kHz switching frequency using PSCAD/EMTDC. The simulation results corroborate the theoretical analysis.
