Abstract
In the hybrid power system, the bidirectional DC/DC converter, as the driving devices for energy storage element, is the core element of hybrid energy storage system and has the function of stabilizing the intermediate DC link voltage. This paper introduces the working principle and the derivation of bidirectional Buck/Boost converter in the process of modeling. A voltage and current double closed loop control system based on load current prediction is designed. When the load changes constantly, the response speed of the system can be improved. Simulation studies using MATLAB/Simulink show that the established model and control strategy can be used for further research.
