Abstract
A wireless charging transmitter includes first and second input terminals for receiving an input voltage from a power source, a coil, an inverter having first and second inverter input terminals coupled to the first and second input terminals respectively, and first and second inverter output terminals for providing an output voltage to the coil. A control system is configured to monitor a voltage between the first and second input terminals, and control the inverter to adjust the output voltage, based on an offset between the monitored voltage and a target voltage, to at least partially compensate the offset. The wireless charging transmitter may further include an ideal diode coupled between one of the input terminals and the inverter.
