Analysis and Design of a New High Voltage Gain Interleaved DC–DC Converter with Three-Winding Coupled Inductors for Renewable Energy Systems

In this article, a new non-isolated interleaved DC–DC converter is proposed to provide high voltage conversion ratio in renewable energy systems. The configuration composed of two-phase boost integrating voltage-lift capacitor and three-winding coupled inductor-based multiplier modules achieve step-up reduce stresses on the semiconductors (switches diodes). can when working at proper duty ratio. switches are significantly lower than output voltage, which enables engineers adopt low-voltage-rating MOSFETs with low on-state resistance. turn under zero-current switching (ZCS) conditions because leakage inductor series reducing losses. Some diodes naturally off ZCS alleviate reverse–recovery issue input current has small ripples due operation. recycled spikes avoided. suitable for applications gain, efficiency power required. principle operation, steady-state analysis design considerations described detail. addition, closed-loop controller designed effect fluctuation load change voltage. Finally, 1000 W laboratory prototype built tested. theoretical performance were validated by experimental results.
