Abstract
This paper proposes a novel high step-up DC-DC converter comprising a single switch and a three-winding coupled inductor. By using only one switch, the proposed converter simplifies control by requiring only one set of PWM signals and eliminates the need for operating at extremely high duty cycles or high turns ratios to achieve the desired gain ratio. Moreover, the converter achieves remarkable voltage gain through a voltage multiplier cell and a three-winding coupled inductor. This paper employed a 500W high step-up converter to confirm the correctness and feasibility of the proposed converter through steady-state analysis, software simulations, and hardware implementation. The measured maximum efficiency reached 95.8% when operated under 150W.
