摘　　要：针对目前矿山井下利用有线方式给巷道LED灯供电时更换灯具存在的不方便以及安全性问题,本文研究了一种巷道LED灯的无线供电装置。设计了单管逆变无线供电主电路,基于互感等效模型详细分析了单管等效电路的工作模态,对输入补偿网络的瞬态电压进行了正弦拟合,分析了单管逆变电路的恒流特性。对电压增益以及电路软开关的实现进行了详细的分析,最后通过实验验证了单管逆变无线供电电路的恒流特性。In view of the inconvenient replacement of lamps and existing safety problems when using wired way to supply power to LED lamps in the roadway, this paper focuses on a wireless power supply device for LED lamps in the roadway. In order to realize non-contact power supply for LED lamps in roadway, this paper designs a single tube inverter wireless power supply circuit. In this paper, based on the mutual inductance equivalent model, the working mode of the single tube equivalent circuit is analyzed in detail. The realization of voltage gain and circuit soft switch is analyzed in detail. Finally, the constant current characteristic of single transistor inverter circuit is verified by experiments.
