Study on digital controller of multi-task interleaving parallel BUCK modules

Abstract

Take three parallel Buck modules for example. By adopting master-slave current sharing technology, a digital controller is designed on the basis of DSP56F807 and C/OS operating system. As the key parts of the research, interleaving parallel technology and current sharing strategy, as well as the scheduling and division of the task modules, is introduced in detail. The parallel power system and the design of real-time multi-task software play a significance role for the improvement of the reliability of the system.
