Wireless power receiver system

A wireless power receiver, the wireless power receiver configured to receive wireless power from a wireless power supply being at least one of close-coupled and mid-range, the wireless power receiver comprising:

• a power output for electrically coupling the wireless power receiver to a remote device;
• a first receiver circuit having a tank circuit, said first circuit having a close-coupled configuration in which said tank circuit is electrically coupled to said power output and a resonator configuration in which said tank circuit is effectively electrically disconnected/isolated from said power output and forms a closed resonant loop;
• and
• a second receiver circuit having an inductor electrically coupled to said power output, said second receiver circuit configured to couple with said closed resonant loop, wherein said first receiver circuit and said second receiver circuit are electrically coupled in parallel to said power output;
• wherein said first receiver circuit and said second receiver circuit are located remote from the wireless power supply.

A method for operating a wireless power receiver, the wireless power receiver configured to receive wireless power from a wireless power supply, the method comprising the steps of:

• providing a power output for electrically coupling the wireless power receiver to a remote device;
• providing a first receiver circuit remote from the wireless power supply, the first receiver circuit capable of being configured to operate as a power supply circuit in close-coupled mode and as a resonator in mid-range mode;
• providing a second receiver circuit remote from the wireless power supply, the second receiver circuit capable of operating as a power supply circuit in mid-range mode, the second receiver circuit tuned to efficiently couple with the first receiver circuit when the first receiver circuit is configured to operate as the resonator, wherein said first receiver circuit and said second receiver circuit are electrically coupled in parallel to the power output;
• determining whether a wireless power supply is a close-coupled wireless power supply or a mid-range wireless power supply;
• upon a determination that the wireless power supply is a close-coupled wireless power supply, configuring the first receiver circuit to operate as a power supply circuit;
• and
• upon a determination that the wireless power supply is a mid-range wireless power supply, configuring the first receiver circuit to operate as a resonator.
