The study of wind energy conversion systems (WECS) has gained attention in the field of renewable energy sources. This is partly because wind generator size has increased quickly, and also because power electronics have developed and can be used to extract wind energy. This article offers a thorough analysis of both historical and contemporary converter topologies that are related to permanent magnet generators and doubly-fed induction generators. Price, power consumption, efficiency, control complexity, and the diverse generator-converter combinations are contrasted on the basis of topology. The attributes of each generator-converter setup are considered from the viewpoint of wind turbine systems.
