Working Principle of the Wind Turbine

Low-power wind power generation mostly uses synchronous or asynchronous AC generators, and the AC power generated is converted into DC power through rectifier devices. The advantages of a synchronous AC generator are its low efficiency and its ability to generate more power than a DC generator at low wind speeds, so it can adapt to a wide range of wind speeds.
