摘　　要：提出了一种磁集成组合式CUK变换器。该组合变换器由2个基本CUK变换器组合而成,同时将变换器中3个电感进行磁集成。通过对组合变换器进行模态及工作性能分析,组合变换器的电压增益是基本CUK变换器的2倍,电感磁集成后电感电流纹波显著降低。分析给出了减小电流纹波磁集成电感耦合度设计准则。仿真和实验验证了理论分析的正确性。磁集成组合式CUK变换器可以应用于光伏、燃料电池等发电系统。A magnetic integrated combined CUK converter is proposed in this paper,which is composed of two basic CUK converters.Meanwhile,three inductors in the novel converter are magnetically integrated.Through the analysis of the mode and operating performance of the combined converter,it is found that the voltage gain of the combined converter is twice that of the basic CUK converter,while the inductance current ripple is significantly reduced after the inductance magnetic integration.In addition,the design criteria for reducing the current ripple coupling degree of magnetic integrated in-ductors are also given.Simulation and experimental results verified the theoretical analysis.The proposed magnetic inte-grated combined CUK converter can be applied to power generation systems such as photovoltaic and fuel cells.
