Title:
MULTI-PATH RESONANT CONVERSION CIRCUIT AND MULTI-PATH OUTPUT CONTROL METHOD BASED ON SAME
Document Type and Number:
WIPO Patent Application WO/2021/139093
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a multi-path resonant conversion circuit and a multi-path output control method based on same. A control circuit in the circuit is used for controlling the working frequency of a first switching tube and the working frequency of a second switching tube, so that the sum of the sum of first electric signals output by a first output end and the sum of second electric signals output by a second output end is equal to a total value of preset electric signals; and the control circuit is further used for controlling the duty ratio data of the first switching tube and the duty ratio data of the second switching tube, so that the ratio of the sum of the first electric signals output by the first output end to the sum of the second electric signals output by the second output end is equal to a preset electric signal ratio. The working frequency of the first switching tube and the working frequency of the second switching tube are controlled by means of the control circuit, so that the first output end and the second output end constantly output electric signals according to the preset ratio, the total value of the output electric signals is equal to the total value of the preset electric signals, and the technical effect of simultaneous multi-path output of a same driver can be achieved.
