A single‐switch high step‐up Zero Current Switching DC‐DC converter based on three‐winding coupled inductor and voltage multiplier cells with quasi resonant operation

Abstract

This paper presents a nonisolated high step-up soft switching DC/DC converter with continuous input and output energy, low input current ripple, and low voltage stress of semiconductors. In this topology, passive clamping circuits are used not only to recycle leakage energy but also to successfully alleviate voltage spikes on the active MOSFET. The leakage inductor, on the other hand, solves the output diode's reverse recovery problem effectively. Furthermore, output capacitors are connected in series to supply the output load, resulting in a smaller output capacitor volume. The suggested topology's operational theory, as well as steady-state analyses, is thoroughly explored. The proposed topology's voltage gain and switch stress are then compared with that of some high-gain topologies. After this, a prototype circuit with a 20 V input voltage, 340 V output voltage, and 200 W output power is designed to test the proposed topology's accuracy.
