Load‐independent inverse class‐E ZVS inverter and its application to wireless power transfer systems

IET Power Electronics, 2022
This paper proposes a load‐independent inverse class‐E zero‐voltage switching (ZVS) inverter. The proposed inverter achieves the constant output current and the ZVS at any load resistance without any control.

iGSE-C$_{\mathrm{x}}$ – a New Normalized Steinmetz Model for Class II Multilayer Ceramic Capacitors

IEEE Open Journal of Power Electronics, 2021
Ferroelectric Class II ceramic capacitors allow for highly compact converter realizations, but are showing relatively high losses for large-signal excitations which must be taken into account in the system dimensioning.
