摘要
针对光伏并网发电系统,提出一种新型非隔离型多路输入变换器。该变换器同时具有零电压导通(ZVT)和高增益能力。此处首先以2路输入为例,分析了该变换器的工作原理及性能特点,然后通过拓扑推演,得到了该变换器的n路输入结构。在此基础上搭建了2路输入,输出功率为100 W的实验样机,实验结果验证了理论分析的正确性。
Forced on the photovohaic grid-connected generation system, a multiple-input converter with the ability of zero voltage turning-on and high step up is proposed.Firstly,the operation principle and characteristic of the converter with dual input are analyzed.Secondly ,the n-input of the converter is deduced.Finally, a dual input experimental pro- totype of 100 W output power is built and the experimental results are provided to validate the proposed eoneept.
