Abstract
Systems and methods are provided for stabilizing power and voltage in dynamic wireless charging (e.g., of electric vehicles). Systems and methods can use a composite control that combines a backstepping control approach with passivity-based control to stabilize output voltage during movement of the load (e.g., travel of the electric vehicle) and/or changing load conditions. As an example, a Lyapunov function-based control method can be used to regulate output voltage and power by controlling a boost converter at the secondary side. Systems and methods can ensure that the output voltage remains independent of load conditions, while also effectively maintaining smooth power delivery even as the load and mutual coupling fluctuate simultaneously, demonstrating rapid response to varying load conditions and mutual coupling.
