Series Oscillatory Circuit with Eddy Losses

An electrical circuit and a mathematical model of a series oscillatory circuit are proposed, which take into account dynamic energy losses due to induced eddy currents. The relationship of the circuit model parameters with the time dependence of the voltage on its capacitive storage device is determined. A method for identifying model parameters using a nonlinear regression function and Vieta’s theorem is proposed. The method is illustrated by the example of identifying the parameters of an oscillatory circuit with an inductance that uses an open magnetic circuit. The proposed approach makes it possible to improve the accuracy of the description of physical processes occurring in oscillatory circuits with eddy losses and assess the level of these losses and the ratio of dynamic and static losses.
