摘要：

The dynamic charging of wireless charging system for electric vehicle can significantly reduce the quality and size of power battery of electric vehicle. Since the operation state of electric vehicle in the dynamic system will change in real time, the optimal system output power demand of power battery is different under different working states. If the system operates with a non-optimal output power, its efficiency and reliability will be affected. This paper proposes a dynamic decoupling control method of output power in wireless charging system for electric vehicle. According to the characteristic that the dynamic decoupling mechanism of the rectifier circuit has less effect on the system, the method can ensure high-efficiency and quick regulation of output power. The mathematical model of the dynamic decoupling control system is established, and the calculation factor of the control scheme is obtained. The decoupling duty cycle is used to control the output power through the calculation factor. The simulation and experimental results show that the dynamic decoupling control overcomes the shortcomings of slow regulation and low efficiency of the conventional regulation mode, and achieves fast output power regulation during dynamic charging process, while the system performance is optimized. © 2019 Automation of Electric Power Systems Press.
