摘要

为解决传统Cuk变换器升压能力不足、应力较大等问题,将Cuk变换器与Boost变换器进行叠加组合,并引入耦合电感双倍压单元,提出一种应用于高增益场合的组合式Cuk-Boost变换器。该变换器增加了以改变耦合电感匝比来调节电压增益的方式,并将拓扑中电容-二极管支路在作为倍压电路的同时还可作为钳位电路来吸收漏感能量,在使用较少元器件的情况下提高了变换器功率密度,降低了电压应力。对变换器工作原理和性能进行分析,给出各项设计参数,对比不同变换器的电气性能,最后通过搭建原型电路验证理论分析的正确性。

Abstract

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.
