Title:
RESONANT CONVERTER AND SYNCHRONOUS RECTIFICATION CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/254536
Kind Code:
A2
Abstract:
A synchronous rectification control method for a resonant converter, comprising: obtaining an output current of a resonant converter; if the output current is greater than a first current threshold, obtaining a first parameter; if the output current is less than a second current threshold, obtaining a second parameter, the first current threshold being greater than the second current threshold, and the first parameter being greater than the second parameter; on the basis of the first parameter, establishing a first current hysteresis loop, and on the basis of the second parameter, establishing a second current hysteresis loop, a parameter of the first current hysteresis loop being the first parameter, and a parameter of the second current hysteresis loop being the second parameter; and using the first current hysteresis loop and the second current hysteresis loop to control synchronous rectification of the resonant converter in a load-switching working condition.
