In this paper, a novel single-switch high-gain DC/DC converter is proposed. The topology combines Boost converter and Cuk converter organically, which not only improves the voltage gain of the converter, but also reduces the voltage stress of the switching tube, and preserves the advantages of current continuity of the original Boost converter and Cuk converter. The converter uses a single switch, only using a single PWM signal can be driven, driven simple and high efficiency. Finally, the correctness and validity of the theoretical analysis are verified by the experimental prototype.
