| 摘 要： | 提出了一种磁集成组合式CUK变换器。该组合变换器由两个基本CUK变换器组合而成，同时将变换器中的3个电感进行了磁集成。通过对组合变换器进行模态及工作性能分析，得到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。

| Abstract: | A magnetic integrated combined CUK converter is proposed. The combined converter is composed of two basic CUK converters and three inductors in the converter are magnetically integrated. By analyzing the mode and performance of the combined converter, it is found that the voltage gain of the combined converter is twice that of the basic CUK converter, and the inductance current ripple is significantly reduced after the inductance magnetic integration. The design criteria for the reducing current ripple coupling degree of magnetic integrated inductors are presented. The simulation and experiment verify the correctness of the theoretical analysis. The magnetic integrated combined CUK converter can be used in photovoltaic, fuel cell and other power generation systems. |
