Abstract：This paper proposed a dual-output inverter for dynamic wireless power transfer(DWPT) system, which can generate two outputs simultaneously to drive two primary tracks(coils). Firstly, the topology and operating principle of the inverter were introduced. Then the inverter output voltage gain, system output power, and stress and soft switching conditions of power switches were analyzed. Finally, experimental verification was carried out. The theoretical analysis and experimental results show that the DWPT system based on the proposed inverter can maintain a high efficiency in the moving process of pickup coil, and the maximum efficiency is more than 90%. Meanwhile, the system has fast dynamic response speed, which can fully meet the requirements of the general DWPT system.
