In this paper, an isolated wind energy conversion system (WECS) based on the cascaded H-bridge multilevel inverter (CHBMLI) topology employing a permanent magnet synchronous generator (PMSG) driven by a variable speed wind turbine and feeding high power single-phase local loads has been proposed. A seven-level cascaded H-bridge inverter employing phase-shifted multi-carrier pulse width modulation...
The paper presents a control strategy for a wind energy conversion system (WECS) for an optimal extraction of power from the wind. The topology of the system consists of a permanent magnet synchronous generator (PMSG), a diode bridge rectifier, a hybrid dc-dc converter which lowers the dc voltage, a supercapacitor and an inverter. However, the grid side inverter is not subject to this paper research...
This paper presents a Z-source inverter for wind energy conversion system. The main thrust in wind energy conversion system (WECS) is to maintain a constant voltage at the output in spite of variation in wind velocity. The Z-source inverter has been identified to exhibit in steady-state, both voltage buck-and boost-capabilities. It employs a unique impedance network included between the dc power source...
