Abstract
Embodiments of the present disclosure provide an electrical apparatus, a power supply system having the same and a method of manufacturing the electrical apparatus. The electrical apparatus includes a detecting circuit coupled to a generator and configured to detect a frequency of the generator. The electrical apparatus also includes a controller coupled to the detecting circuit and configured to receive a first signal indicating the detected frequency and adjust the frequency of the generator in response to determining that the detected frequency is out of a predetermined frequency range. In this way, an actively controlling of the changing rate of the power to and from generator may be achieved, if the generator frequency exceeds the configured limits.
