Abstract: 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.

Abstract: A power electronics device 10 comprises at least one power module 16 comprising power semiconductors 20, a controller 22 for controlling the power semiconductors 20, and an auxiliary power supply 22 for powering the controller 22; and a rack 14 for supporting the power module 16. The power module 16 comprises a first inductor 40 attached to the power module 16 and electrically connected to the auxiliary power supply 22. The power electronics device 10 comprises a second inductor 42 attached to the rack 14, such that the second inductor 42 is galvanically separated from the first inductor 40. In an installation position of the power module 16 in the rack 14, the first inductor 40 and the second inductor 42 are inductively coupled, such that electrical power is transferable from the second inductor 42 to the first inductor 40. The power module 16 is removable from the installation position, such that the inductive coupling between the first inductor 40 and the second inductor 42 is interrupted.
