Document Type and Number:
Japanese Patent JP5804303
Kind Code:
B2
Abstract:
The primary winding (L1) of a step-up transformer (16) is connected to a drive circuit (12) that generates an AC voltage. One end of the secondary winding (L2) of said step-up transformer (16) is connected to one end of an induction coil (L3) used for magnetic-field coupling and is also connected to a passive electrode (E5) used for electric-field coupling. Active electrodes (E1 through E4) work in concert with said passive electrode (E5) to implement electric-field-coupling power transfer. The other end of the secondary winding (L2) of the step-up transformer (16) is connected to the induction coil (L3) and the active electrodes (E1 through E4) via a switch (SW1). A control circuit (14) identifies the power-transfer scheme used by a power-reception apparatus placed on a placement surface of a housing and controls the connection state of the aforementioned switch (SW1).
