POWER CONVERTER FOR REDUCING STANDBY POWER CONSUMPTION

摘要

There is provided a power converter for reducing 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.

1. 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 one side of the first external switch; a second external switch configured to provide an enable signal, with one side of the second external switch connected to a 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 one side of the second external switch.
