초록

Segmented dynamic wireless power transfer (DWPT) systems can solve the problems of large battery size, long charging time, and the limited driving range of electric vehicles (EVs). Aiming at the load voltage fluctuation caused by the mutual inductance drop when moving over two adjacent transmitting coils, this paper proposes a novel segmented DWPT system with dual receiver topology circuits. The current phase difference between two adjacent transmitting coils is controlled to 180 degrees. The dual receiver topology circuits are in series to improve the output voltage. According to the real-time position of the EV, the system has two working modes under the control of the proposed topology, which consists of three fully controlled components and six diodes. Finally, experiments were carried out and the obtained results show that the designed topology is effective when it comes to reducing the voltage fluctuation when passing two adjacent transmitting coils. In addition, the topology is able to maintain a high transmission efficiency with a maximum efficiency of 87.68%.
