Abstract (en)
[origin: EP1541440A1] The method involves applying a generator voltage to a first input coupling coil (1) of the oscillation circuit, applying a generator voltage to second input coupling coil (2) of the oscillation circuit so that the magnetic field generated by the second input coupling coil opposes that from the first coil, whereby the input coupling coils interact with a resonator coil (3) of the oscillation circuit so that the input coupling coils act as the primary side and the resonator coil as the secondary side of a transformer (10). Independent claims are also included for the following: (A) an electromagnetic oscillation circuit for implementing the inventive method (B) and an axle counting point with an electronic rail contact with an inventive electromagnetic oscillation circuit.
