Evaluation of a Primary-Side Parameters-Agnostic Power Regulation Method on Different WPT Topologies

A recent paper has introduced a primary-side control methodology for Wireless Power Transfer (WPT) links, capable of delivering, by only sensing quantities available at the primary side (i.e., the power transmitter), the optimal power level to the load without compromising the system efficiency. Indeed, this technique has been validated only on an ad-hoc WPT system relying on an isolated class-E DC-DC power converter based on inductive coupling. In this paper we provide results, through SPICE simulations, by applying the proposed approach to different state-of-art WPT systems, either inductively or capacitively coupled, in order to improve the generality of the adopted control methodology and to extend the validity of the method beyond the circuit topology considered in the original paper.
