DBD tranformerless power supplies: impact of the parasitic capacitances on the power transfer.

Journal of Physics: Conference Series, 2017
A new transformerless power supply for DBD application is presented here. The power supply is built with 10kV SiC MOSFET. This high voltage switches allow holding the high voltage required by the DBD. An analytical study of the converter's operation is presented to deduce the power transmitted to the DBD.

New Insight of Maximum Transferred Power by Matching Capacitance of a Wireless Power Transfer System [PDF]

Energies, 2017
Most research on wireless power transfer (WPT) has been focused on how to achieve a high-efficiency power transfer. Our study found that under the impedance matching for achieving maximum WPT efficiency, the power transferred to the load cannot reach the maximum when a WPT system is supplied by an AC voltage source with constant amplitude. However, the
