Analysis, modeling and simulation of power and information transmission channel in an electromagnetic induction fuze setting system

Accepted models of power and information transmission channel in electromagnetic induction fuze setting systems are not accurate because the effects of eddy currents in the fuze body are not taken into account. This paper establishes an improved accuracy mathematical model that fully considers the influence of eddy currents on the system, and the model is consisted of mutual inductance model of isolated transformer and eddy current loop. Through analyzing the model, the optimum working conditions are deduced, and the problem of leakage compensation is also explored. ANSYS multiphysics simulation software is used to analyze the the process of electromagnetic induction setting aiming at two different fuzes. Differences in secondary voltage output on both sides of the fuze body are also compared. Consistency between simulation and theoretical analysis is clearly demonstrated. This constitutes a significant advance in engineering design.
