Title:
BIDIRECTIONAL DC/DC CONVERTER AND CONTROL METHOD THEREFOR AND APPARATUS THEREOF, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/193765
Kind Code:
A1
Abstract:
The present application provides a bidirectional DC/DC converter and a control method therefor and an apparatus thereof, and a storage medium. The control method comprises: acquiring a first voltage value output by a first rectification module within the current control period; acquiring a second voltage value output by a second rectification module within the current control period; calculating a theoretical voltage control quantity of a bidirectional DC/DC converter within the current control period according to a preset reference voltage value and the second voltage value; and setting an actual output voltage of the bidirectional DC/DC converter within the next control period according to the theoretical voltage control quantity and the first voltage value. Voltage tracking errors within a next control period can be reduced. Moreover, since there is no need to use a PI parameter to perform control, an output theoretical voltage control quantity is no longer a frequency but a switch signal, such that a phenomenon of frequency hopping when switching can be avoided.
