Abstract
A power supply system for controlling the power supply system includes a direct current voltage conversion apparatus, an inverter, and a diode. The direct current voltage conversion apparatus includes a controller and a direct current voltage conversion circuit. The controller is configured to: control the output voltage of the direct current voltage conversion circuit, so that the diode is in a conducted state; detect a voltage on the direct current bus; and determine, based on the voltage on the direct current bus, whether high voltage ride-through occurs in the power supply system. According to the power supply system and the method for controlling the power supply system provided in this application, high voltage ride-through can be quickly detected while fault isolation is implemented, thereby improving efficiency of detecting high voltage ride-through.
