US 2026/0163364 A1 · DC ENERGY-CONSUMING APPARATUS AND CONTROL METHOD, APPARATUS THEREOF AND STORAGE MEDIUM

Abstract

A direct-current energy-consuming apparatus, a method and a device for controlling a direct-current energy-consuming apparatus, and a storage medium are provided. The direct-current energy-consuming apparatus includes an energy-consuming resistor, a power module, an inductor and a control module. The inductor is arranged in a branch formed by the energy-consuming resistor and the power module connected in series. The control module is configured to switch off the power module when it is detected that a voltage between two ends of the direct-current energy-consuming apparatus is greater than a first voltage threshold, and switch on the power module, when it is detected that a voltage between two ends of the direct-current energy-consuming apparatus is less than a second voltage threshold, where the two voltage thresholds are determined based on a rated voltage of a corresponding direct-current power transmission system.
