摘要：

In order to solve the problems of insufficient boost capacity and high stress of the traditional Cuk converter，the Cuk converter and the Boost converter are superimposed and combined，the coupled inductor double voltage unit is introduced，and a combined type Cuk-Boost converter used in high-gain situations is proposed. The converter adds a way to adjust the voltage gain by changing the turns ratio of the coupled inductor. The capacitor-diode branch in the topology can be used as a voltage double circuit and a clamp circuit to absorb the leakage inductor energy. In the case of less components，the power density of the converter is increased，and the voltage stress is reduced. The working principle and performance of the converter are analyzed，various design parameters are given，and the electrical performance of different converters are compared. Finally，the correctness of the theoretical analysis is verified by building a prototype circuit. © 2023 Science Press. All rights reserved.
