Title: SYSTEM FOR WIRELESS POWER CHARGING
Abstract:
According to a first aspect of the present disclosed subject matter, a system for wirelessly charging a device by a transmitter capable of receiving messages from a device, the system comprising: a configurable driver for inductively transfer power level for charging the device; a controller configured to control the driver and continuously measuring currents and voltages of the transmitter while the charging, wherein the control is tuning the power level by reconfiguring the driver with parameters selected from a group consisting of operating frequency; duty cycle; amplitude; and any combination thereof, based on the measuring indicating a power level deviation or resetting another power level based on messages.
