Power electronic converters have been developed several tenths of years ago for many types of applications. One of its major applications is for control of electrical machines, mainly used in the beginning for industrial applications, and now propagated in many household appliances. The beginning of the renewable energy story had a moderate influence on the power electronic converters market. Indeed, in the old small wind turbines, the mechanical power was converted to electrical power thanks to induction machines directly connected to the grid. Very quickly, the power of the wind turbine increased and more rules were implemented.
