The power transportation industry such as electric vehicles is developing rapidly. It effectively uses green energy by reducing the use of fossil energy, and can realize alternative energy processing units, thereby bringing feasibility to future smart-grid power systems. In addition, wireless power transfer (WPT) is the main direction of the future electric power transportation charging technology. In view of this, this paper proposes a new power processing method for wireless electric transportation systems. It has the advantages of not requiring an additional input transformer and realizing bidirectional power flow. In addition, new parameter optimization methods and control strategies of the electric transportation charging system based on finite control set model predictive control method are proposed. Simulations and experimental results show that the proposed method has higher efficiency and better performance.
