Description
technical field [0001] The invention belongs to the technical field of electrical control, and more specifically relates to a multi-module system current sharing control method, device and terminal equipment. Background technique [0002] In existing multi-module systems, current sharing occurs only when multiple electrical modules are started at the same time. If the starting time of each electrical module is inconsistent, such as starting successively, the sudden change in the feedback caused by the sudden change will lead to a sudden change in the error amount in each electrical module. Uneven flow occurs. [0003] Therefore, how to realize the current sharing control of the multi-module system has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a multi-module system current sharing control method, device and terminal equipment, so as to realize the current sharing...
