Title:
RESONANCE TYPE NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/014482
Kind Code:
A1
Abstract:
A resonance type non-contact power supply system that supplies power through a primary resonance coil and a secondary resonance coil. The resonance type non-contact power supply system includes power supplying equipment and movable body equipment. The power supplying equipment includes a primary coil unit, which is provided with the primary resonance coil, and a distance detector, which detects the distance between the primary and secondary resonance coils. The movable body equipment includes a switch and a terminal resistor. When the distance detector detects the distance, the switch connects the terminal resistor to the secondary coil unit and disconnects a rectifier and power storage device from a secondary coil unit. When the movable body equipment receives power, the switch connects the rectifier and the power storage device to the secondary coil unit and disconnects the terminal resistor from the secondary coil unit.
