Title:
CONVERTER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/065588
Kind Code:
A1
Abstract:
The present application provides a converter and a control method therefor. The converter comprises a main switch transistor, an auxiliary switch transistor, a transformer, and a controller. After the converter operates, the controller obtains the output voltage of the converter and obtains a mode switching parameter on the basis of the output voltage of the converter; and controls the converter to switch between a first working mode and a second working mode according to the mode switching parameter. By adopting the present application, the efficiency of the converter under the full-range output voltage can be optimized.
