VOLTAGE CONVERSION CIRCUIT AND METHOD, AND MULTI-PHASE PARALLEL POWER SUPPLY SYSTEM

Title:

VOLTAGE CONVERSION CIRCUIT AND METHOD, AND MULTI-PHASE PARALLEL POWER SUPPLY SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/032269

Kind Code:

A1

Abstract:

Disclosed are a voltage conversion circuit and method, and a multi-phase parallel power supply system. A feedback circuit provides a frequency-controllable feedback ripple signal, so that the working frequency of the voltage conversion circuit can be controlled, so as to meet the requirement of a load on a frequency. Moreover, a lag mode does not require compensation, and a response speed is high. Moreover, since the working frequency is fixed, the voltage conversion circuit can be applied to the multi-phase parallel power supply system, so that the multi-phase parallel power supply system can satisfy a heavy-load current application scenario.
