This paper describes the voltage equalization compensation loop structure of a three-level bidirectional DC/DC converter based on fuzzy PI control, analyzes the architecture of the fuzzy PI controller, establishes a comprehensive and effective rule library, and realizes the correction of the fuzzy PI parameters of the voltage equalization compensation loop structure. It was tested using a simulation system built on the Matlab/Simulink platform, and the results showed that the improved control strategy can quickly and stably achieve voltage equalization control of the bus divider capacitor.
