Wind Power Generation

Wind turbine generators create power from natural wind. They are becoming more popular globally as a clean method of power generation that is environmentally friendly.

Wind turbines with increased blade lengths to raise the amount of power generated per turbine are becoming the mainstream type of power generator. The output power of wind power generators is converted to DC power in an AC/DC converter, and then converted from DC power to commercial frequency AC power by an inverter.Fuji Electric supplies IGBT modules that are suitable for conversion circuits that are required to have a large capacity.
