Analysis of Control Strategies for Three-level DC/DC Converters in Charging and Discharging Systems
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.
