Application Overview
A wind turbine is a device that converts kinetic energy from wind into mechanical energy that is used to drive a generator
to produce electricity. Large grid-connected arrays of turbines are becoming an increasingly important source of
commercial electric power. Wind turbine systems are usually generators with more than 2 MW of power and typically
variable speed types. Solid-state power converters are used to interface the generator and power transmission system.
Conversion efficiency, high reliability, and low maintenance are typical requirements for these systems. In addition, all
wind turbine systems must be equipped with safety systems to prevent damage due to high wind speed or any other gridor system-related problems.
