POWER SUPPLY APPARATUS, METHOD FOR POWER SUPPLY APPARATUS, AND REDUNDANT POWER SUPPLY SYSTEM

Abstract

A power supply apparatus includes a power converter, a controller, an ORing device, and a first feedback module. The power converter is configured to provide an output voltage via the ORing device. The first feedback module is connected between a downstream node of the ORing device and the controller and is configured to provide a first voltage feedback to the controller. The power supply apparatus further includes a second feedback module connected between an upstream node of the ORing device and the controller and configured to provide a second voltage feedback to the controller, and a third feedback module connected between the upstream node of the ORing device and the controller and configured to provide a third voltage feedback to the controller. The controller is configured or programmed to control the power supply apparatus based on the first voltage feedback, the second voltage feedback, and the third voltage feedback.
