A LOW - COST PMSG TOPOLOGY AND CONTROL STRATEGY FOR SMALL - SCALE WIND POWER GENERATION SYSTEMS

Developing a low - cost power converter for small - scale wind turbine systems using permanent magnet synchronous generators (PMSG) is one of the hot topics in the wind power generation research. Using minimum number of switches with high efficiency is the target of this proposal. The proposed converter consists of six - switches in th e generator and grid side. The DC - link side is divided into two capacitors with mid - point to connect the third phase of the PMSG to this point. The topology and the control strategy is implemented and the validity of this topology is validated by using PSI M software
