| 摘 要： | 提出了一种可应用于光伏发电系统的含耦合电感低电压应力Boost变换器。因传统的Z 源Boost变换器开关元件直接与负载相连而具有较高的电压应力，所提出的变换器通过耦合电感将开关元件与负载进行了隔离，可以有效减小开关元件的电压应力。新的变换器不仅保留原Z 源网络优点，同时可以在占空比相同的情况下通过调节耦合电感匝比来获得更高的电压增益。简要分析了所提拓扑的运行流程，并通过仿真验证了所提拓扑的可行性。

| Abstract: | This paper presents a low voltage stress Boost converter which can be applied to photovoltaic system.Because of the switch of the traditional Z source Boost converter connected with load directly with high voltage stress,the proposed converter isolations switch element and load by coupled inductor,the voltage stress of the switching element reduced effectively.The new converter not only retains the advantages of the original Z source network, but also can obtain higher voltage gain by adjusting the ratio of the coupled inductor at the same duty cycle. The operation process of the proposed topology is analyzed, and the feasibility of the proposed topology is verified by simulation. |
