  • Self-excitation of switched reluctance generators during load bus faults
    Patent number: 7638985
    Abstract: A self-excited, switched reluctance generator obtains excitation energy from a capacitor bank via an excitation bus during normal operation. During a short-circuit or load fault, one or more phases of the generator provide power to the excitation bus while the remaining phases send current to a faulted positive bus. The system does not require an external battery or power source for excitation energy. The system is capable of resuming normal operation after the load bus fault.
    Type: Grant
