This paper presents an overview of technologies for wind energy conversion into electrical energy with the help of residential wind turbines. The theory of wind energy conversion into mechanical energy is shown. Wind velocity distribution and normalised energy yield examples are given to improve understanding of wind energy availability and converter operation modes. Additionally the wind velocity dependency of the height above ground is explained. The pros and cons of wind turbine generators are analysed. Converter topologies galvanically isolated for interfacing a permanent magnet synchronous generator based variable speed wind turbine with a residential power network is analysed. Main emphasis is on the combination of a rectifier and an isolated quasi-Z-source (qZS) based DC/DC converter topology proposed by the authors. The topology (rectifier coupled with a qZS based galvanically isolated step-up DC/DC converter) is essential to generate regulated DC voltage (400 V DC typical for 230 V AC output) despite wide variations in the output voltage of a wind generator. The operation principle of the proposed topology is described. Experimental and simulation results are presented and analysed.
