Title:
MOTOR THREE-PHASE CURRENT UNBALANCE COMPENSATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051219
Kind Code:
A1
Abstract:
The present disclosure provides a motor three-phase current unbalance compensation method and apparatus, an electronic device, and a computer readable storage medium. The method comprises: calculating a target peak current corresponding to a three-phase current of a motor in real time; performing peak sampling on the three-phase current to obtain a corresponding actual peak current; on the basis of the target peak current and the actual peak current, determining a three-phase current unbalance amount; on the basis of the three-phase current unbalance amount, determining a compensation voltage; and on the basis of the compensation voltage, compensating for the three-phase current. The present disclosure can realize real-time compensation of three-phase current unbalance under the condition that no additional device is increased.
