Abstract
A dual wireless power transfer system is disclosed having an input power supply providing power at a first voltage V1 and a first wireless power transmission system receiving power at a first power input from the input power supply, the first wireless power transmission system including a first transmitter antenna and a first driver for driving the first transmitter antenna for wireless power transmission to a first wireless receiver system and wireless receipt of data from the first receiver system, wherein data wirelessly received at the first transmitter antenna from the first receiver system at least partially feeds back onto the first power input. A second wireless power transmission system includes a second transmitter antenna and a second driver for driving the second transmitter antenna for wireless power transmission to a second wireless receiver system. A low voltage drop out receives power from the input power supply at V1 and provides power at a preselected lower voltage V2 to the second wireless power transmission system, such that V2 is independent of data received at the first transmitter antenna.
