| Abstract: | 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. |
