“…Achieving this significantly low output voltage value necessitates the use of switching devices with minimal voltage drops. The switching circuit can be implemented with MOS-FETs characterized by low current and low breakdown voltage, operating in a synchronous buck converter configuration [31]. However, to reduce the current ripple, a high switching frequency of the buck converter would be beneficial.…”

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.

“…Despite the small Q G of the chosen MOSFET, the FOM is very favorable to the GaN FET device, as shown in the graph of Figure 9a, related to the results in Table 1. The output capacitor C oss is a parameter related to the switching losses [21,40]. The MOSFET shows a higher C oss than the GaN FET.…”

High-electron-mobility transistors based on gallium nitride technology are the most recently developed power electronics devices involved in power electronics applications. This article critically overviews the advantages and drawbacks of these enhanced, wide-bandgap devices compared with the silicon and silicon carbide MOSFETs used in power converters. High-voltage and low-voltage device applications are discussed to indicate the most suitable area of use for these innovative power switches and to provide perspective for the future. A general survey on the applications of gallium nitride technology in DC-DC and DC-AC converters is carried out, considering the improvements and the issues expected for the higher switching transient speed achievable.

“…An input voltage V i = 3.3 V is chosen to avoid the operation with an extremely low duty cycle. The switching circuit can be realised using low current and low breakdown voltage MOSFETs operating in synchronous stepdown converter topology [30]. A lower current ripple and a higher precise regulation can be achieved by increasing the switching frequency, as represented in Fig.…”

In this paper, an LCC-S compensated wireless power transfer system regulated by a variable inductor is presented. The inductance variation is performed by exploiting the magnetic material saturation of the inductor core, regulating the DC bias. The magnetic design of the controlled variable inductor is proposed. A low-cost auxiliary circuit for the regulation of the bias current is proposed, and the performance is evaluated. The effect of the inductance variation on the output power regulation and conversion efficiency are evaluated through an experimental setup.
