Power supply and control method thereof

Abstract

The present invention discloses a power supply and a control method thereof. The power supply comprises a power conversion unit, a current sampling circuit, and a signal comparison unit. The power conversion unit converts a power source based on an input power source, generates an output current, has a power source output terminal, and outputs the output current from the power source output terminal. The current sampling circuit samples a transient variation of the output current and to generate an output voltage difference signal corresponding to the transient variation. The signal comparison unit is electrically connected to the current sampling circuit, receives the output voltage difference signal, and compares the output voltage difference signal with a predetermined voltage value. When the output voltage difference signal is greater than or equal to the predetermined voltage value, the signal comparison unit generates a dynamic compensating command.
