Power control system and method of controlling the same

摘要

A power control system provides an output power control for a generator. The power control system includes a power conversion unit, a sensing unit, a load-dumping unit, and a control unit. The power conversion unit receives and converts a current and a voltage, generated from the generator, to supply a load. The sensing unit receives the current and the voltage to produce a current signal and a voltage signal. The load-dumping unit is connected to the generator and the power conversion unit. The control units receives the current signal and the voltage signal, produces a current control signal to control the power conversion unit, and generates a voltage control signal to control the load-dumping so as to control the output power of the generator.
