摘要

基于减少组件数的开关电容升压逆变器是太阳能光伏发电利用与高频运行交流系统的最新发展。更高的电压增益,用于自电压平衡的无传感器系统使基于sc的多电平逆变器(mli)成为光伏应用的完美选择。在本文中,提出了具有9电平输出的升压逆变器拓扑结构,其特征是输入电压的升压。采用单个输入源,12个半导体器件实现4倍的电压增益,而三个源电压等级的电容器表现出电压的自平衡。通过仿真结果对所提出的9L-SCBI在各种条件下进行了测试,并通过多个实验结果对所提出的9L-SCBI进行了实验验证。

A High Gain 9L Switched-Capacitor Boost Inverter (9L-SCMI) With Reduced Component Count
The switched-capacitor boost inverters based on the reduced component count has been the latest development for solar PV utilization along with ac systems with the high-frequency operation. The higher voltage gain, sensorless system for self-voltage balancing makes SC-based multilevel inverters (MLIs) a perfect choice for PV applications. In this article, a boost inverter topology with 9 level output has been presented which features the boost of the input voltage. A voltage gain of four is achieved with a single input source, 12 semiconductor devices while three capacitors of source voltage rating exhibit the self-balancing of their voltage. The proposed 9L-SCBI is tested under various conditions through simulation results and experimentally validated with several experimental results.
