A system for a charging a vehicle is provided. The system includes a power generating device and one or more controllers. The power generating device is configured to generate a first energy signal corresponding to a requested amount of voltage for one of a vehicle and a base pad during a vehicle charging operation. The controller is configured to receive a request indicative of the requested amount of voltage to provide to the vehicle during the vehicle charging operation and to control the power generating device to generate the first energy signal based on the request. The controller is further configured to determine a resonant frequency of the first energy signal and to adjust a capacitance of a tuning capacitor network based on the determined resonant frequency to compensate for a distance variation between a vehicle pad and the base pad during the vehicle charging operation.
