WIRELESS POWER TRANSFER METHOD, APPARATUS AND SYSTEM
First Claim
1. A wireless power transfer method for a wireless power transfer apparatus using full and half-bridge inverter topologies, the method comprising:
- 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.

19. A wireless charging system comprising:
-
a wireless power transmitter configured to transmit power in a wireless manner; and a wireless power receiver configured to receive the power from the wireless power transmitter in the wireless manner, wherein a power transfer unit of the wireless power transmitter comprises an LC circuit configured to be switched between a full-bridge and a half-bridge, wherein the wireless power receiver informs the wireless power transmitter of whether or not the wireless power receiver itself corresponds to a medium power receiver or a low power receiver such that the wireless power transmitter decides whether to drive the power transfer unit using either the full-bridge or the half-bridge. - View Dependent Claims (20)
