Abstract
A wireless power transfer system includes a wireless power transmission system and a wireless power receiver system. The wireless power transmission system includes a transmission antenna, a transmission controller, and a transmission power conditioning system. The transmission controller is configured to provide a driving signal for driving the transmission antenna based on an operating frequency and a virtual AC power frequency. The transmission power conditioning system is configured to generate the virtual AC power signals at the operating frequency and having peak voltages rising and falling based on the virtual AC power frequency. The wireless power receiver system includes the receiver antenna and the power conditioning system. The receiver power conditioning system is configured to receive the virtual AC power signals, convert the virtual AC power signals to alternating current (AC) received power signals, and provide the AC input power signals to a load.
