摘要
为解决变间隙条件下传统磁共振耦合无线能量传输技术无法维持能量稳定高效传输的问题,基于非线性宇称时间对称原理,提出一种新型变间隙无线能量传输方法。利用电压放大器的非线性增益饱和机制,构建宇称时间对称电路模型。通过电路分析方法推导出系统传输效率和谐振频率的精确解析解,并通过仿真结合实验方法验证了理论模型的正确性。在两线圈直径为90 mm条件下,利用所搭建的实验系统给某引信供电。结果表明:两线圈间距离在30～120 mm范围内变化时,系统能够满足能量稳定高效传输;通过理论、仿真及实验结果验证,所提出的变间隙无线能量传输方法有效可行。
In order to solve the problem that the traditional magnetic resonance coupled wireless energy transmission technology can not maintain stable and efficient energy transmission under the condition of variable gap,a pseudo-symmetric circuit model is constructed by using the nonlinear gain saturation mechanism of voltage amplifier based on the principle of nonlinear parity time( PT) symmetry,and a new energy transmission method with variable clearance is proposed. The accurate analytical solutions of system transmission efficiency and harmonic frequency are deduced by analyzing the circuit model of the transmission system,and the correctness of the theoretical model is verified by using a simulation-experiment method. The experimental system is used to power a fuze under the conditions of two coils with a diameter of 90 mm. The results show that the system can meet the stable and efficient transmission of energy when the distance between the two coils changes within the range of 30-120 mm. The theoretical,simulated and experimental results show that the proposed variable gap wireless energy transmission method is effective and feasible.
