摘要: A transient voltage compensation apparatus and a power supply using the same are provided. The power supply mainly uses an energy transferring circuit coupled between an input terminal and an output terminal of a power converter. When a load of the power supply is switched in a very short time, a power coupled to the energy transferring circuit is retrieved to compensate the output of the power supply, such that the output voltage is kept steady, and the transient response of the power supply is increased.
