Reverse voltage protection for brushless excitation systems |
摘要 |
A protective circuit is provided for a brushless excitation system using a rotating rectifier assembly to supply field excitation to a synchronous generator. A thyristor is connected across the generator field winding and made conductive when the field winding voltage exceeds a preset level to shunt the field winding and protect the rectifier diodes against high reverse voltages.
