RESONANCE TYPE NON-CONTACT POWER SUPPLY SYSTEM
First Claim
1. A resonance type non-contact power supply system comprising:
- power supplying equipment including an alternating-current power source and a primary-side resonance coil for receiving power from the alternating-current power source; and
movable body equipment including a secondary-side resonance coil for receiving power from the primary-side resonance coil, a rectifier for rectifying the power received by the secondary-side resonance coil, and a secondary battery to which the power rectified by the rectifier is supplied, andwherein;
the power supplying equipment includes a primary matching unit provided between the alternating-current power source and the primary-side resonance coil, and a primary matching unit adjusting section for adjusting the primary matching unit, andthe primary matching unit adjusting section is configured to adjust the primary matching unit only at times other than when detecting the distance between the primary-side resonance coil and the secondary-side resonance coil.

Abstract
A power supplying equipment includes an alternating-current power source and a primary-side resonance coil. A movable body equipment includes a secondary-side resonance coil a rectifier, and a secondary battery to which the power rectified by the rectifier is supplied. The power supplying equipment further includes a primary matching unit provided between the alternating-current power source and the primary-side resonance coil, and a primary matching unit adjusting section for adjusting the primary matching unit. The primary matching unit adjusting section adjusts the primary matching unit only at times other than when detecting the distance between the primary-side resonance coil and the secondary-side resonance coil.
