What is provided is: a wind turbine comprising a rotor (110) having at least two rotor blades (108), an electrical generator (200), which is coupled directly or indirectly to the rotor (110) and generates an electric power, and at least one power electronics unit (300, 400), which is provided for converting an input voltage with an input frequency into an output voltage with an output frequency. The power electronics unit (300, 400) has at least one varistor unit (500). The varistor unit (500) has at least one varistor disk (530) having a voltage-dependent resistance and at least one metal disk (540), which is provided in contact with the at least one varistor disk (530) and is provided as cooling element for cooling the varistor disk (530). |
