Title:
NON-CONTACT POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/022365
Kind Code:
A1
Abstract:
There is provided a non-contact power transmission device capable of effectively reducing the device size and reducing the higher harmonic component which is unwantedly emitted from the primary side coil. The non-contact power transmission device includes a primary side unit and a secondary side unit which can be separated from each other and separately contain a primary side and a secondary side of a connection transformer. A capacitor C1 resonating with the primary side coil L1 is connected in series to the primary side coil L1, thereby forming a primary side series resonator circuit. An L-shaped resonator circuit having a coil L3 and a capacitor C7 resonating with the coil L3 is inserted between the primary side series resonator circuit and the drive circuit. The L-shaped resonator circuit is connected in series to the primary side series resonator circuit.
