摘要： A power supply includes an EMI filter removing noises from an input signal, a rectifying circuit rectifying and outputting the input signal, and a power factor correction circuit varying a magnitude in output voltage according to a duty ratio of a driving signal while generating an output voltage by an energy storage unit storing and discharging energy, controlling the duty ratio of the driving signal according to the change in the output voltage, and controlling the magnitude in output voltage before the output voltage is determined to be in an overvoltage state by using a second threshold voltage to be set lower than the first threshold voltage while determining whether the output voltage is in an overvoltage state by using the first threshold voltage. The power supply controls the magnitude in output voltage before it is determined that the output voltage is in an overvoltage state by being overshot.
