Abstract
A power converter according to examples reduces standby power consumption. The power converter includes 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 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, a first capacitor that is connected in parallel to one side of the first external switch, a second external switch configured to provide an enable signal, and a second capacitor that is connected in parallel to one side of the second external switch.
