“…2, where the output power profile of a 100 W WPT system is proposed as a function of the input inductance value. A controlled variable inductor, whose inductance can be accurately regulated, allows the active and continuous regulation of the output power [13]. The basic principle of a controlled variable inductor (CVI) is the variation of the permeability of a ferromagnetic material.…”

“…This control method, known in the literature as the magnetic control technique, is widely adopted in other resonant converter topologies such as the LLC or DAB resonant converters [21,22]. The principles of magnetic control can also be applied to regulate power transmission in the context of IWPT systems effectively [23,24]. There are several methods for implementing the magnetic control strategy.…”

The paper explores the use of the magnetic control strategy for the output power regulation of an LCC‐S compensated inductive wireless power transfer system. The magnetic control is implemented through a controlled variable inductor whose magnetization state is actively regulated by an auxiliary DC–DC converter. The principles for the design and regulation of the system are discussed, and the experimental setup for the validation of the regulation method is implemented. Several measurement results highlight the effectiveness and potential improvements of the magnetic control strategy for inductive wireless power transfer systems.

“…This variation is obtained by designing the inductor with an additional coil where ad DC current is flowing. Changing the value of the DC current it is possible to change the point of working along the B-H curve of the material [16]. The principle of operation of the converter has been widely proven in [14].…”

This paper presents a control strategy for output voltage regulation of the LCC-S compensated Wireless Power Transfer (WPT) system through a variable inductor. Firstly, the architecture of the system is analyzed, and the relation between the output voltage and the variable inductance is derived. Then, the control strategy that allows to regulate the DC current through the variable inductor to maintain the desired output voltage is presented. Both the steady-state and the dynamic performance of the system are evaluated through Simulink simulations.
