Title:
RESONANT CONVERTER, POWER SUPPLY, TERMINAL AND BOOSTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/237431
Kind Code:
A1
Abstract:
The present application relates to a resonant converter, a power supply, a terminal and a boosting method. The resonant converter comprises a winding transformer and a booster circuit. The winding transformer comprises at least one group of secondary windings, and each group of secondary windings comprises a first secondary winding and a second secondary winding. The first secondary winding is connected in series with the second secondary winding. The winding transformer converts a voltage supplied by the power supply, outputs the converted voltage from the first secondary winding in a positive half cycle of the voltage supplied by the power supply, and outputs the converted voltage from the second secondary winding in a negative half cycle of the voltage supplied by the power supply. The booster circuit boosts the voltage outputted by the first secondary winding in the positive half cycle of the voltage supplied by the power supply, and boosts the voltage outputted by the second secondary winding in the negative half cycle of the voltage supplied by the power supply. The resonant converter may reduce the size of the winding transformer by means of reducing the cross-sectional area of a magnetic core, thereby reducing the size of a power supply product. Meanwhile, the ripple of the output voltage of the power supply can be greatly reduced.
