Abstract: Dynamic systems may require a large number of coils (charging pads) which may be installed into the roadway to wirelessly provide power to electric vehicles as they are traveling along the roadway. The current in each of these coils may need to be turned on and off as a vehicle drives over the coils in order to efficiently utilize power and properly convey power to the passing vehicles. The supply network behind these coils may need to be capable of managing the individual coils with minimal infrastructure and cost as well as be capable of distributing the required power from the power grid to these pads efficiently and safely. The supply network may include charging coils, switches, local controllers, and distribution circuitry within a modular element, which may receive power from external sources and may be controlled by a central controller.
