La presente invención se refiere a un circuito de protección de un aerogenerador que incluye un filtro entre el bus DC del convertidor y tierra, proporcionando un camino adicional a las corrientes de tierra del sistema, reduciendo de este modo las sobretensiones entre fase y tierra en bornes del generador. The present invention relates to a protection circuit for a wind-power generator that includes a filter between the DC bus of the converter and earth, providing an additional path for the earth currents of the system, thereby reducing excess voltages between phase and earth at terminals of the generator.
