Title:
MULTI-PHASE POWER SUPPLY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/000199
Kind Code:
A1
Abstract:
A multi-phase power supply and an electronic device. The multi-phase power supply comprises at least two-phase power supply circuit. When each phase of the at least two-phase power supply circuit supplies power to a load device, load voltage at both ends of the load device are obtained by means of a first feedback end and a second feedback end of this phase of power supply circuit. In a case that the load voltage is not equal to the reference voltage, a set voltage-regulating proportion corresponding to this phase of power supply circuit is adjusted, so that the load voltage is as close to the reference voltage as possible, improving the power supply stability of multi-phase power supply.
