Abstract
A wireless power transfer method for a wireless power transfer apparatus using full and half-bridge inverter topologies includes detecting whether or not a wireless power receiver is present within a range of power being transferrable in a wireless manner, transmitting a detection signal to the wireless power receiver, receiving at least one of identification information and setting information from the wireless power receiver, receiving a control error packet from the wireless power receiver, and controlling an amount of power to be transferred by using the combination of a driving frequency, a duty cycle or a power signal phase to the full or half-bridge inverter.
