Abstract

With the development of wireless power transfer (WPT), dynamic wireless power transfer (DWPT) has become a key technology for solving the low driving range of electric vehicles. This study aims to alleviate the output fuctuation of the power supply rail of a bipolar transmitter during DWPT, and to meet the wide output voltage range requirement at the receiving end. Specifcally, a cascaded interleaved three-level buck converter is developed as a power topology at the receiving end to efectively reduce the electrical stress of the switching device. In addition, a control method that combines active disturbance rejection control and a disturbance observer is proposed to suppress the output fuctuation of the coupling coil at the receiving end and to improve the dynamic response speed, which efectively enhances the output stability of the DWPT system. In this paper, a 30 kW DWPT experimental platform is established to verify the superiority of the cascaded three-level buck converter and the efectiveness of the proposed control method. The proposed control method has a 40% higher fuctuation suppression capability when compared with the traditional control method.
