Self-balancing stator antenna for optimized contactless energy transfer from stator to rotor in near-field telemetry system for vehicle, has microprogram adjusting network such that energy at inlet is implemented in maximum amplitude

摘要

The antenna (1) has a processor (7) controlling a digitally adjustable matching network (4) by an algorithm based on evaluation of an output signal adaptation detector. A microprogram adjusts the matching network such that maximum energy at an inlet (15) in an induction coil (2) is optimally implemented in maximum magnetic field amplitude. The digitally adjustable matching network consists of a set of stepwise insertable capacitors and serial branches with fixed capacitance and parallel branches with adjustable capacitors.
