RESONANCE TYPE NON-CONTACT POWER SUPPLY SYSTEM

摘要

A power supplying equipment (10) includes an alternating-current power source (11) and a primary-side resonance coil (13b). A movable body equipment (20) includes a secondary-side resonance coil (21b) a rectifier (23), and a secondary battery (25) to which the power rectified by the rectifier (23) is supplied. The power supplying equipment (10) further includes a primary matching unit (12) provided between the alternating-current power source (11) and the primary-side resonance coil (13b), and a primary matching unit adjusting section (14) for adjusting the primary matching unit (12). The primary matching unit adjusting section (14) adjusts the primary matching unit (12) only at times other than when detecting the distance between the primary-side resonance coil (13b) and the secondary-side resonance coil (21b).
