Abstract
A wireless power transmission system includes a transmission antenna, a transmission controller, and a transmission power conditioning system. The transmission antenna is configured to couple with a receiver antenna and transmit virtual AC power signals to the receiver antenna. 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 includes at least one transistor that is configured to receive the driving signal, at a gate of the at least one transistor, and to receive an input power signal 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.
