<p>PROBLEM TO BE SOLVED: To provide a compact and light non-contact charging method. SOLUTION: As a coil for transmitting power, a drum-type choke coil 2 is used. As a coil for charging, a coil 4 for charging is formed while the drum- type choke is covered. In this state, a DC voltage is applied to the drum-type choke coil 2 and is switched at a proper frequency for allowing current to flow to the dry-type choke coil 2, magnetic energy is generated for converting to electric energy by the coil 4 for charging, and the electric energy is rectified by a rectifying diode 5 and is charged to a capacitor 6 for charging to drive a load 7.</p> |
