Modeling of Vortex Flow of High Power Inductors Losses with Foliate Cores in Ground-Based Positioning System

The Laurent local current transmitter of ground-based Positioning System uses several High power inductance ferrite or metal cores. Nonlinear behavior of these inductors with transient frequency variations in the case of fluctuations is of much importance in flow losses and in the efficiency of the transmitter. In this paper, the relations of vortex flow losses in high power solenoids with foliate cores are presented. On the other hand, it is shown that these relations can be used as a reference model at different frequencies for high-power inductors with foliate cores. The results of modeling and simulation show the effects of nonlinear parameters in the inductor on the performance of the transmitter's inductors. The paper will reveal that the 100 kHz frequency of the Laurent flow transmitter is the boundary of reducing the rate of loss of vortex flow and increasing efficiency in this transmitter. It also shows that under this frequency, the losses of the vortex flow are proportional with and above this frequency with f2.
