GENERATOR BRAKE SYSTEM AND METHOD OF CONTROLLING THE SAME

摘要

The present invention provides a generator brake system for providing a brake control of a generator. The generator brake system includes a power conversion unit, a sensing unit, and a control unit. The power conversion unit receives an output voltage and an output current, generated from the generator, and the power conversion unit has at least one switch unit. The sensing unit receives the output voltage and the output current to generate a voltage signal and a current signal. The control unit receives the voltage signal and the current signal. When receiving a braking signal, the control unit generates at least one control signal for correspondingly turning on the at least one switch unit, thus braking the generator in a short circuit manner.

1. A generator brake system for providing a brake control of a generator driven by an external torque, the generator brake system comprising:
a power conversion unit receiving an output voltage and an output current, generated from the generator, and the power conversion unit having at least one switch unit; a sensing unit receiving the output voltage and the output current, and generating a voltage signal and a current signal; and a control unit receiving the voltage signal and the current signal; wherein the control unit controls the output voltage to be gradually reduced when the control unit receives a brake signal; the control unit generates at least one control signal to correspondingly turn on at least one switch unit so as to brake the generator in a short circuit manner when the output voltage is less than a threshold voltage.
