RESONANCE TYPE NON-CONTACT POWER SUPPLY SYSTEM

WIPO Patent Application WO/2012/014483

A1

A resonance type non-contact power supply system including power supplying equipment and movable body equipment. The power supplying equipment includes an AC power supply, a primary resonance coil, which receives power from the AC power supply, and a controller, which controls the AC power supply. The movable body equipment includes a secondary resonance coil, a rectifier, a power storage device, a distance detector, and a high frequency power supply. The secondary resonance coil receives power from the primary resonance coil. The distance detector and high frequency power supply cooperate with each other to detect the distance between the primary resonance coil and the secondary resonance coil. When the distance detector detects the distance, the controller holds the AC power supply in a standby state. After the distance detector detects the distance, the controller activates the AC power supply to supply power.
