Title:
ADAPTIVE POWER AMPLIFIER FOR OPTIMIZING WIRELESS POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2018/076690
Kind Code:
A1
Abstract:
A system apparatus and method for providing wireless power transmission from a WPT transmitter to a receiver A switching device is configured to have a first part coupled to a first part of the WPT transmitter (104), and a second part coupled to a second part of the WPT transmitter (104). A controller (106) can determine whether an adaptive power supply provides an expected power quantity. The switching device is configured to control the first and second parts of the switching device, so that the adaptive power supply can be selectively operated between a single-end mode and a differential mode in order to provide the expected power quantity optimization efficiency.
