CONTACTLESS POWER SUPPLY SYSTEM

摘要

A contactless power supply system includes a feeder line through which a high-frequency current flows and a pickup unit inductively coupled to the feeder line. The contactless power supply system is configured to supply electric power to a load by an electromotive force induced in the pickup unit. The pickup unit includes a tubular core circumferentially surrounding the feeder line and a coil formed of a coil wire wound on the core. The core is provided with an inner surface, an outer surface and an opening extending in an axial direction of the feeder line so that at least the feeder line passes through the opening in a radial direction. At least one of the inner surface and the outer surface of the core is formed into a curved surface shape.
