Document Type and Number:
WIPO Patent Application WO/2022/205718
Kind Code:
A1
Abstract:
A phase-shifted full-bridge converter, a control method and device thereof, and a medium. The method comprises: after a current input current of a phase-shifted full-bridge converter is obtained, selecting a working mode corresponding to the current input current according to a preset correspondence between an input current and a working mode, and under a current working mode, acquiring a phase shift angle of the phase-shifted full-bridge converter and the switching frequency of a switch transistor in the phase-shifted full-bridge converter according to a maximum power point tracking algorithm to control the switch transistor to execute a corresponding action. By applying the technical solution, when an input current is changed, a switch transistor in a phase-shifted full-bridge converter can be controlled under different modes according to different input currents, and a rapid change of the input current is responded in time, so that the maximum power tracking efficiency and stability are ensured, and the requirements of a system are further satisfied.
