| Sumario: | This article presents a novel single-switch soft-switching high step-up dc–dc boost converter. By utilizing a coupled inductor and series capacitors in the output stage, the converter achieves soft switching performance for the power switch during turn- on and turn- off , along with a high step-up voltage gain. The design of the coupled inductors enables the simultaneous achievement of soft switching and high voltage gain without the need for additional auxiliary circuits, ensuring circuit simplicity and high efficiency. Furthermore, the converter maintains continuous input current, similar to a boost converter, improving battery lifespan and renewable input power source operation. The proposed converter addresses diode reverse recovery issues and incorporates a common ground between input and output stages, simplifying the feedback circuit. Comparative analysis with similar high-efficiency high step-up boost converters is performed, and a 200-W laboratory prototype is implemented. |
