Power converter for reducing standby power consumption

A power converter, comprising:

• a rectifier configured to rectify AC power into DC power;
• a transformer configured to output power by converting a voltage of DC power rectified by the rectifier;
• a Pulse Width Modulation (PWM) control module configured to control an output power by switching a power switching device connected to the transformer;
• a first external switch configured to provide a disable signal, with one side of the first external switch connected to a VCC pin of the PWM control module and the other side of the first external switch connected to a DIS pin of the PWM control module;
• a first capacitor that is connected in parallel to the one side of the first external switch and to a ground;
• a second external switch configured to provide an enable signal, with one side of the second external switch connected to the DIS pin of the PWM control module and the other side of the second external switch connected to the ground;
• and a second capacitor that is connected in parallel to the one side of the second external switch and to the ground.
