Abstract
A control method for reducing audio noise is disclosed. The method includes the steps of: providing an input power source; providing a power source converter having a component with a mechanical resonant frequency, coupled to the input terminal or the output terminal of the power source converter; providing an output capacitor and a load connected in parallel therebetween; making the power source converter operate in a burst mode; and controlling the electrical energy transferred from the input terminal to the output terminal of the power source converter during an operating period of every burst cycle, so as to reduce the audio noise of the power source converter.
