| الوصف: | Abstract With the continuous progress of new energy technology, new energy vehicles have ushered in a stage of rapid development. As the central core of new energy vehicle, the power accumulator batteries have been attracting increasing attention. To obtain the exact electrical characteristics of the power battery, battery charging and discharging are integral component. A bidirectional grid‐connected AC/DC converter with predictive load‐feedforward compensation is presented in this article. Derive a predictive load‐feedforward model from the state space model of the rear DC/DC converter to reduce the bus voltage fluctuations caused by load variations. Firstly, the system structure for battery charging and discharging system is presented, and then the underlying principle of predictive load‐feedforward control is analyzed. Secondly, the predictive load‐feedforward model is built and discussed. Finally, build a system simulation model in MATLAB/Simulink and set up an experimental platform in the lab. Simulation results show that the predictive load‐feedforward control can reduce the bus voltage fluctuation and regulation time by about 84% and 50%, respectively, when the load power varies substantially. The findings of experimental studies also indicate that with predictive load‐feedforward control can significantly suppress bus voltage fluctuations and improve the dynamic response of the converter. |
