Title:
非接触給電システム
Document Type and Number:
Japanese Patent JP7378084
Kind Code:
B2
Abstract:
To downsize a secondary coil to contribute to the downsizing of equipment with a built-in load in a magnetic resonance contactless power supply system.SOLUTION: A magnetic resonance type contactless power supply system includes a power transmission unit having a primary coil connected to a power source and a power receiving unit having a secondary coil connected to a load, and the primary coil and the secondary coil arranged to face the primary coil are resonated, such that power is transmitted from the power transmitting unit to the power receiving unit, the primary coil and the secondary coil are solenoid types in which a conducting wire is wound around a magnetic core, and the wire diameter of the conducting wire constituting the secondary coil is smaller than the wire diameter of the conducting wire constituting the primary coil.SELECTED DRAWING: Figure 2
