Title:
NON-CONTACT POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/034894
Kind Code:
A1
Abstract:
AC current (I1) from a primary power source (1) flows into a primary coil (3a) of
a non contact power supply transformer (3) via a power supply line (2) and generates
a magnetic field in the vicinity of the primary coil (3a). The magnetic field runs
down to a secondary coil (3b) of the non-contact power supply transformer (3)
and current (I2) flows in the secondary coil (3b). The current (I2) flows to a power
reception unit (4) and a constant DC voltage output V is outputted to an output
terminal of the power reception unit (4). The constant DC voltage output V is applied
to a load (6) and a large-capacity capacitor (5) to charge the large-capacity
capacitor (5). When operation is performed with a maximum load, the charge charged
in the large-capacity capacitor (5) is fed to the load (6).
