Abstract
A resonance type non-contact charging apparatus is disclosed. A charger of the apparatus receives the high frequency power from a secondary side resonance coil of the apparatus. A power ratio detecting section of the apparatus detects the ratio of the reflected power from a primary side resonance coil to the high frequency power source with respect to the output power from the high frequency power source to the primary side resonance coil. A stop control section of the apparatus stops the high frequency power source when the ratio detected by the power ratio detecting section becomes greater than or equal to a predetermined threshold value.
