Permanent-magnet synchronous generators (PMSGs) are attracting considerable attention in wind energy conversion systems (WECSs) due to their numerous advantages such as low weight and volume, high performance, and the elimination of the gearbox. In this paper, a new variable-speed WECS with a PMSG and a three-phase three-leg AC/AC converter as power electronic interface between PMSG and network is proposed. Characteristics of nine-switch AC/AC converter are used for maximum power tracking control under different wind speed and delivering power to the grid, simultaneously. This configuration has low manufacturing cost compare to conventional topologies. Two simulations are performed for proposed configurations and results are presented. The results verify effectiveness of the proposed interface configuration.
