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

Abstract

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,
