Title:
MULTI-PHASE SIGNAL CONTROL CIRCUIT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/211059
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronics, and provided therein are a multi-phase signal control circuit and method, which are used for solving the problem in the prior art in which the switching period of a PWM signal is not stable, which causes a rear-stage power stage circuit to operate abnormally. The multi-phase signal control circuit comprises: a comparator which is used for comparing a triangular wave signal and a feedback control signal so as to output a first pulse width modulation signal, wherein the feedback control signal is a signal fed back by a power stage circuit; a phase-cutting circuit which is used for receiving a phase switching signal and the first pulse width modulation signal so as to generate a first phase signal and a second phase signal, the first phase signal and the second phase signal being used for controlling the power stage circuit to generate an output voltage signal.
