Novel High Step-Up Soft-Switching DC–DC Converter Based on Switched Capacitor and Coupled Inductor

A novel high step-up dc-dc converter with coupled inductor and switched capacitor is proposed in this article. The proposed converter adopts capacitors charged in parallel and discharged in series with a coupled inductor to achieve high step-up voltage gain. By utilizing the energy stored in the leakage of the coupled inductor, both of the switches can realize zero-voltage switching, which can reduce switching loss and improve efficiency. In...
