Wireless power transfer systems for kitchen appliances

A wireless power transmission system for providing wireless power to a kitchen appliance, the kitchen appliance comprising (i) a control device and (ii) a wireless power receiver system comprising (a) a first receiver antenna and (b) a second receiver antenna, the wireless power transmission system comprising:

• a first transmission power conditioning system that is operable to (i) receive a first driving signal, (ii) receive a first input power signal, and (iii) based on the first driving signal and the first input power signal, produce a first alternating current (AC) signal (i) at a first operating frequency and (ii) comprising a waveform that has peak voltages rising and falling based on a virtual AC power frequency;
• a first transmission antenna that is operable to (i) receive the first AC signal from the first transmission power conditioning system and (ii) based on the first AC signal, produce a first wireless power signal at the first operating frequency and in accordance with the waveform;
• a second transmission power conditioning system that is operable to (i) receive a second driving signal, (ii) receive a second input power signal, and (iii) based on the second driving signal and the second input power signal, produce a second AC signal at a second operating frequency for transferring wireless power and data in-band of the wireless power;
• a second transmission antenna that is operable to (i) receive the second AC signal from the second transmission power conditioning system and (ii) based on the second AC signal, produce a second wireless power signal at the second operating frequency;
• and
• at least one transmission controller that is operable to (i) receive control instructions in-band of the second wireless power signal, (ii) generate the first driving signal based on (a) the control instructions received in-band of the second wireless power signal from the control device of the kitchen appliance, (b) the first operating frequency, and (c) the virtual AC power frequency, and (iii) generate the second driving signal based on the second operating frequency.

A kitchen appliance comprising:

• a control device that is operable to (i) receive, from a user interface, input, (ii) based on the input, generate control instructions for a wireless power transmission system, the control instructions configured to control the transmission of a first wireless power signal, and (iii) provide the control instructions to a wireless power receiver system operatively associated with the kitchen appliance;
• the wireless power receiver system comprising:
• a first receiver antenna that is operable to (i) receive the first wireless power signal from a first transmission antenna at a first operating frequency and having peak voltages rising and falling based on a virtual AC power frequency, (ii) based on the first wireless power signal, produce a first received AC signal at the first operating frequency and having peak voltages rising and falling based on the virtual AC power frequency;
• a first receiver power conditioning system that is operable to (i) receive the first received AC signal from the first receiver antenna, (ii) convert the first received AC signal to an AC power signal that oscillates at an AC power frequency that is based on the virtual AC power frequency, and (iii) provide the AC power signal to a first load of the kitchen appliance;
• a second receiver antenna that is operable to (i) receive a second wireless power signal at a second operating frequency from a second transmission antenna and (ii) based on the second wireless power signal, produce a second received AC signal at the second operating frequency;
• a second receiver power conditioning system that is operable to (i) receive the second received AC signal, (ii) convert the second received AC signal to a direct current (DC) power signal, and (iii) provide the DC power signal to at least a receiver controller, the control device of the kitchen appliance, or combinations thereof;
• and
• the receiver controller is operable to (i) receive the control instructions from the control device, and (ii) encode the control instructions in the second wireless power signal.
