Resonance type non-contact charging device
First Claim
1. A resonance type non-contact charging device comprising:
- a high frequency power source,a primary side resonant coil receiving supply of high frequency electric power from said high frequency power source,a secondary side resonant coil arranged apart from said primary side resonant coil in a non-contact manner, receiving electric power from the primary side resonant coil through magnetic field resonance between said primary side resonant coil and secondary side resonant coil,a charger receiving supply of high frequency electric power from said secondary side resonant coil,a secondary battery connected to said charger, anda stop control unit stopping said high frequency power source before said charger is stopped when charging is to be stopped.

Abstract
A resonance type non-contact charging device includes a high frequency power source, a primary side resonant coil, a secondary side resonant coil, a charger, a secondary battery, and a stop control unit. The primary side resonant coil receives supply of high frequency electric power from the high frequency power source. The secondary side resonant coil is arranged apart from the primary side resonant coil in a non-contact manner. The secondary side resonant coil receives electric power from the primary side resonant coil through magnetic field resonance between the primary side resonant coil and the secondary side resonant coil. The charger receives supply of high frequency electric power from the secondary side resonant coil. The secondary battery is connected to the charger. The stop control unit stops the high frequency power source before stopping the charger when charging is to be stopped.
