Wireless Power Transfer in Coupled Links: Coil Misalignment Model for Electric Cars

Abstract

A  design  procedure  is  established  to  maximize  coil  coupling  for  a  given  configuration  to  reduce  the  effects  of
misalignment  on  transmission  efficiency.  Formulas  are  derived  for  the  mutual  inductance between  all  possible
coil  configurations  including  the  coils  of  the  cross  section,  thin  solenoids,  Pancakes  and  filamentary  circular
coils  whose  axes  are  laterally  and  angularly  displaced.  Coils  are  in  air.  In  this  approach  we  use  the  filament
method  and  the  mutual  inductance  between  filamentary  circular  coils  placed  in  any  desired  positions.  We
completely describe all mathematical procedures to define coil positions that lead to a relatively easy method for
calculating  the  mutual  inductance  between  previously  mentioned  coils.  The  practical  coils  in  implantable
devices  fall  into  two  categories:  disk  coils  and  solenoid  coils.  From  the  general  approach  for  calculating  the
mutual  inductance  between  coils  of  the  rectangular  cross  section  with  lateral  and  angular misalignments,  the
mutual inductance between misalignment solenoids and disks will be calculated easily and accurately.
