This application discloses a bus capacitor discharging method and a related device thereof. The discharging method is applicable to a DC/DC converter, and the DC/DC converter includes a chopper unit, a transformer, and a rectifier unit. A bus capacitor is coupled to the chopper unit, the chopper unit is coupled to a primary side of the transformer, a secondary side of the transformer is coupled to the rectifier unit, and the chopper unit and the rectifier unit are both coupled to a controller. During specific implementation, when determining to discharge the bus capacitor, the controller may control the rectifier unit to short-circuit the secondary side of the transformer, and control the chopper unit to close a loop formed between the bus capacitor and the primary side of the transformer. Implementing this application can reduce costs, and ensure high security.
