Abstract: Embodiments of the present disclosure relate to an uninterruptible power supply. The uninterruptible power supply comprises a switch, a power management module, an inverter and a controller. The switch is arranged between a load and a power source, the power source configured to supply power to the load. The power management module comprises a main energy storage and configured to reduce a ripple experienced by the main energy storage. The inverter is arranged between and coupled to the power management module and the load. The controller is coupled to the power management module, the inverter and the switch, the controller configured to control the inverter to regulate output voltage magnitude and frequency by regulating the power exchange between the inverter and the power source. According to embodiments of the present disclosure, the overcharging of the energy storage during sudden load rejections or utility phase jumps can be avoided.

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.
