为了提高传统级联Boost变换器的电压增益、减小支路电感电流纹波，减弱开关管电压应力、减小变换器的体积，本文将磁集成技术、开关电感和储能电容应用到级联Boost变换器中，提出了新型级联型磁集成开关电感高增益Boost变换器。通过引用两个开关电感和储能电容可以使本文提出的变换器的电压增益提高为传统级联Boost变换器的4倍。利用磁集成技术合理设计出耦合电感系数不仅可以有效减小变换器电感支路的电流纹波与开关器件的电压应力，同时还提高了系统暂态响应速度，减小了变换器的体积重量，从而提高变换器的电气性能。仿真和实验结果验证了理论分析的正确性。

Novel Cascaded Magnetically Integrated Switching Inductor High-gain Boost Converter

In order to improve the voltage gain of traditional cascaded Boost converters, reduce the branch inductor current ripple, reduce the voltage stress of the switches, and reduce the converter volume, In this paper, magnetic integration technique, interleaving technology, switching inductance and energy storage capacitor are applied to the traditional cascaded Boost converters. referring to the two switching inductors and energy storage capacitors leads to that voltage gain of the converter proposed in this paper can be increased to 4 times as much as traditional cascaded Boost converter. Using magnetic integrationtechnique and rational design of coupling inductance coefficient can not only reduce current ripple of branch inductance and reduce the voltage stress of the switches,, but also improve the systemtransient response speed, reduce the volume weight of the converter, thus improve the electrical performance of converter. Simulation and experimental results verify the correctness of the theoretical analysis.
