Large-Scale Wind Turbine With Quasi-Z-Source Inverter and Battery

2021 22nd IEEE International Conference on Industrial Technology (ICIT), 2021
Grid connection of permanent magnet synchronous generator -based wind turbines can be performed through a three-stage power conversion system: 1) uncontrolled rectifier, 2) DC boost converter, and 3) voltage source inverter. In this paper, this topology is modified by replacing the two intermediate stages by a quasi-Z-source inverter (qZSI ...

Research on an improved version of Quasi-Z source inverter

IET International Radar Conference 2013, 2013
Traditional Quasi-Z source inverter uses direct zero vector to realize single-stage buck-boost. However, with the rising of output voltage, the capacitor voltage's increasing adds requirements for devices. A kind of modified Quasi-Z source topology is put proposed.
