Title:
DRIVING CONTROL METHOD, DRIVING CONTROL CIRCUIT AND SYSTEM FOR TOTEM-POLE BRIDGELESS CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/206684
Kind Code:
A1
Abstract:
A driving control method, a driving control circuit and a system for a totem-pole bridgeless circuit. Said method comprises: acquiring, for each return transistor to be controlled in a totem-pole bridgeless circuit, a return transistor voltage of the return transistor to be controlled, and generating a first control signal by comparing the return transistor voltage with a first control reference voltage (S301); and simultaneously acquiring an alternating-current input voltage of the totem-pole bridgeless circuit, and generating a second control signal by comparing the alternating-current input voltage with a second control reference voltage (S302); and processing a first driving control signal and a second driving control signal to obtain a driving control signal for controlling the return transistor to be controlled (S303).
