Abstract :
An electric brake for wind turbine systems is proposed in this paper. Effective emergency electrical braking is needed if an overvoltage occurs due to grid failure. The derived circuits use high power thyristors corresponding to the high values of generated power from today´s wind turbines. A practical confirmation with BLDC a generator is ongoing in the laboratory. The principle of operation is proved by the carried out simulations.
