Summary In this paper, a new DC–DC converter with high voltage gain is proposed. One inductor, three capacitors, a three‐winding coupled inductor, three diodes and one power switch is employed in the presented structure. Because of connecting inductor, the input current of the presented converter is continuous with low ripple. The stored energy in the leakage inductor is recycled by a passive voltage clamp. The voltage clamp also reduces the voltage stress on the main power switch. Since the voltage stress of the switch is low, a switch with low on‐resistance (RDS(ON)) can be used in the proposed converter which reduces the conduction loss. High efficiency, low voltage stress, low input current ripple, low voltage stress on the power switch and zero current switching of the switch are the advantages of the proposed converter. The proposed converter is analyzed in steady state condition and the experimental results are presented to justify the feasibility of the proposed topology.

A single-switch ultra-high voltage DC-DC converter is proposed in this paper. In the introduced structure, a voltage multiplier cell (VMC) and three-winding coupled inductor (CL) are integrated to obtain an ultra-large voltage gain. The input current ripple of the presented configuration is very low due to utilizing an inductor in the input part of the converter which is a very important factor in clean energy applications. The CL leakage inductance energy is successfully recovered, and the main power switch voltage stress is clamped because of using a passive clamp circuit. Therefore, a switch with low os-state resistance can be applied, which declines the conduction losses as well as the cost of the suggested topology. Moreover, the common ground between the input and output of the proposed configuration makes it suitable for many applications such as photovoltaic systems. Some important merits include ultra-high voltage gain, operating in low duty cycles, reduced voltage stress of semiconductors, continuous input current, and high efficiency, which make the introduced converter very suitable for clean energy applications. The operation principle, steady-state analysis, design considerations, and theoretical efficiency analysis of the suggested converter are discussed completely in the paper. Also, the superiority of the proposed converter over recently suggested similar most important DC-DC converters is demonstrated in the comparison study. Finally, the performance and theoretical analysis of the converter are validated with the experimental results at an output voltage of 450 V and an output power of 250 W.
