摘　　要：传统非接触供电系统谐振补偿不够充分,导致两端传输电压相位不同、供电传输效率较差。为此,设计了基于移相控制的并联谐振型非接触供电系统。在硬件设计中优化供电装置,重新定义耦合线圈和主控电路,使其满足芯片驱动电压要求。在软件设计中计算供电电压谐振补偿参数,确保两端输出电压同相,再获取开关管最优移相角比例,得到供电最小回流功率,使系统工作在回流功率最小状态。实验结果表明:相比于传统系统,本文系统提高了电力传输效率,且电机设备在启动和移动过程中能够保证输出电压的稳定性。The resonant compensation of traditional non-contact power supply system is not sufficient, which leads to different voltage phase and poor power supply transmission efficiency. To this end, a parallel resonant non-contact power supply system based on phase shift control is designed. In the hardware design, the power supply device is optimized, and the coupled coil and main control circuit are redefined to meet the requirements of chip driving voltage. In the software design,the resonant compensation parameters of power supply voltage are calculated to ensure that the output voltage at both ends is in phase, and then the optimal phase shift. Angle ratio of the switching tube is obtained to gain the minimum back-flow power of power supply, so that the system can work in the minimum back-flow power state. The experimental results show that compared with the traditional system, this system can improve the power transmission efficiency and ensure the stability of the output voltage during the starting and moving of the motor.
