Title:
CONTROL METHOD AND APPARATUS FOR THREE-PHASE POWER SUPPLY CONVERSION CIRCUIT, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/087629
Kind Code:
A1
Abstract:
The present application discloses a control method and apparatus for a three-phase power supply conversion circuit, a device, and a storage medium. The method comprises: acquiring respective operating power values of a full-bus load and a half-bus load of a three-phase power supply conversion circuit; on the basis of the acquired operating power values, adjusting a voltage magnitude relationship of a half bus of the three-phase power supply conversion circuit. A positive bus and a negative bus of the three-phase power conversion circuit are connected in series with two stages of electrolytic capacitor, the full-bus load is a load connected between the positive bus and the negative bus, and the half-bus load is a load connected to two ends of any capacitor among the two stages of electrolytic capacitors; half buses comprise: an upper half bus between the midpoint of the two stages of electrolytic capacitor and the positive bus, and a lower half bus between the midpoint of the two stages of electrolytic capacitor and the negative bus.
