Zusammenfassung:	The present invention is concerned with an inductive power transfer system for providing power to a gate drive on medium or high electrical potential. The inductive power transfer System has a first spiral coil (11) having a front side facing an axially displaced second coil (12) magnetically coupled to the first coil. Inner or central turns of the first coil are arranged in and define a first coil plane (110), while outer turns of the first coil extend axially out of the first coil plane and are bent away from the second coil. The geometric field grading achieved by this arrangement decreases a maximum electric field strength at the surface of the coil conductors, and thus simplifies the insulation tasks.
