Improved Efficiency of Two‐Stage Partial Power Processing Architectures for Inductive Power Transfer

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a high‐efficiency two‐stage inductive power transfer (IPT) system with partial power processing to reduce energy losses in conventional cascaded architectures. By processing only partial power through the DC/DC converter, the system minimizes losses, lowers component stress, and improves power density.

Oxyfluoride glasses obtained through incorporation of CaF2${\rm CaF}_2$ into photovoltaic cover glass melts

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract The glass industry has limited options to mitigate its environmental footprint, and the demand for cover glass to produce photovoltaic panels continues to increase. Currently, the majority of this special type of glass is not being recycled; therefore, this work proposes to reuse it as raw material to obtain oxyfluoride glasses.
