摘要

本文介绍了一种用于太阳能光伏发电的三相准z源中性点箝位逆变器的工作原理和改进的空间矢量调制策略。这种拓扑结构结合了中性点箝位和准z源逆变器的优点。这些优点包括单级降压升压功率转换、连续输入电流和开关的低电压应力。仿真结果验证了所提出的概念。

Quasi Z-source NPC inverter for PV application
This paper presents the operating principles and modified space vector modulation strategy for a three-phase quasi Z-source neutral point clamped inverter for solar photovoltaic applications. This topology combines the advantages of the neutral point clamped and quasi Z-source inverters. These advantages include single-stage buck-boost power conversion, continuous input current, and low voltage stress of switches. Simulation results are presented to verify the presented concepts.
