Abstract
A pinless power coupling arrangement comprises at least one pin-less power jack, the power jack comprising a primary coil shielded behind an insulating layer for inductive coupling to a pin-less power plug. The power plug comprises a secondary coil wherein said insulating layer is substantially flat and the power plug and the power jack may be aligned by an alignment means. Various such alignment means are discussed as are enabled surfaces for supporting inductive power jacks and inductive plugs coupled to various appliances.
Claims23
An inductive power transfer system comprising:
- a power-outlet positioned on a side of a surface layer, the power-outlet comprising:
- at least one primary coil;
- a driver for driving the at least one primary coil;
- an electromagnetic radiation receiver;
- and
- a secondary unit positioned on an opposite side of the surface layer, wherein the secondary unit is used to supply power to a load and comprising:
- at least one secondary coil used to receive power transmitted by the at least one primary coil;
- and
- an electromagnetic radiation transmitter configured to transmit to the electromagnetic radiation receiver a modulation signal that is based at least in part on monitoring said power to the load;
- and
- wherein the modulation signal provides at least one indication of alignment of the at least one secondary coil with respect to the at least one primary coil and to regulate a duty-cycle of the driver.
A power-outlet to be positioned on a side of a surface layer for inductively powering a secondary unit to be positioned on an opposite side of the surface layer, wherein the secondary unit that supplies power to a load has at least one secondary coil and an electromagnetic radiation transmitter, the power-outlet comprising:
- at least one primary coil used for the powering the at least one secondary coil;
- a driver for driving the at least one primary coil;
- an electromagnetic radiation receiver used for receiving from the electromagnetic radiation transmitter a modulation signal that is based at least in part on monitoring of the power to the load;
- and
- wherein the modulation signal provides an indication of alignment of the at least one secondary coil with respect to the at least one primary coil and to regulate a duty-cycle of the driver.
A secondary unit to be positioned on a side of a surface layer for suppling power to a load, wherein the secondary unit is inductively powered by a power-outlet to be positioned on an opposite side of the surface layer, wherein the power-outlet has at least one primary coil and an electromagnetic radiation receiver, the secondary unit comprising:
- at least one secondary coil used to receive power transferred by the at least one primary coil;
- an electromagnetic radiation transmitter used for transmitting a modulation signal to the electromagnetic radiation receiver, wherein the modulation signal is based at least in part on monitoring of power supplied to the load;
- and
- wherein the power-outlet utilizes the modulation signal for providing at least one indication of alignment of the at least one secondary coil with respect to the at least one primary coil and to regulate the power transferred by the at least one primary coil.
