A wireless vehicle charging system includes at least one controller configured to operate an inverter to control a voltage input to a power converter in a vehicle to drive an impedance phase angle at an output of the inverter toward a predetermined angle and achieve a power demand at an output of the vehicle power converter. The at least one controller is further configured to operate the vehicle power converter to achieve the power demand. The at least one controller may control a frequency output of the inverter to adjust the voltage input to the power converter based on a rate of change of an objective function that is configured to reduce an output power error of the power converter and an impedance phase angle error at the output of the inverter.
