Abstract: In order to solve the problem of energy wireless transmission efficiency reduction in the process of fuze inductive setting, a wireless power transmission self-adaptive control method of fuze was proposed based on the generalized detuning quantity of the coupling loop. Firstly, the mathematical model of the secondary loop current was constructed to be used for the proposal of self-adaptive control method. Then, the control signals of voltage-controlled-oscillator was generated by testing the current rate based on the generalized detuning quantity of the coupling loop to maximize the secondary circuit current so that wireless energy transmission would be controlled adaptively. Finally, secondary coil feedback hardware circuit was constructed based on the equivalent secondary loop, and the method was also verified by experiments. The experimental results show that the control method is feasible and effective.
