摘要 |
<p>A power supplying section has a signal transmitting secondary coil which is not coupled to a power transmitting primary coil not only electrically but also magnetically, and actuates as a feedback coil of a switching element. A load section has a power transmitting secondary coil arranged so as to be confronted with the power transmitting primary coil when the load section is attached to power supplying section, and also has a signal transmitting primary coil so as to be confronted with the and the signal transmitting secondary coil when the load section is attached to power supplying section. When the load section is not attached to the power supplying section, the voltage is not induced in the signal transmitting secondary coil as the feedback coil, and the switching of the switching element is intermittently carried out. <IMAGE></p> |
