RESONANCE TYPE NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A resonance type non-contact power supply system that supplies power through a primary-side resonance coil and a secondary-side resonance coil, the resonance type non-contact power supply system comprising:
- power supplying equipment including an AC power supply, a primary coil unit, which includes the primary resonance coil, and a distance detector, wherein the primary resonance coil receives power from the AC power supply, and the distance detector detects the distance between the primary resonance coil and the secondary resonance coil; and
movable body equipment including a secondary coil unit, which includes the secondary resonance coil, a rectifier, a power storage device, a switch, and a terminal resistor, which is connectable by the switch to the secondary coil unit;
wherein the second resonance coil receives power from the primary resonance coil, the rectifier rectifies the power received by the secondary resonance coil, and the power storage device is supplied with power rectified by the rectifier;
wherein when the distance detector detects the distance, the switch connects the terminal resistor to the secondary coil unit and disconnects the rectifier, and the power storage device from the secondary coil unit; and
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.

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.
