Upcycling Solar Glass Into Ce‐Doped Oxyfluorides: Spectroscopic and Crystallization Properties

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Oxyfluorides containing up to 75 wt% of recycled glass from end‐of‐life solar panels have been investigated. Reduced processing temperature and high transparency have shown that the material has potential for optical applications. In this work, cerium‐doped samples were investigated. Spectroscopic study reveals the presence of Ce3+${\rm Ce}^{3+

Impact of QSW‐ZVS on Input EMI Filter Design in DC‐DC Converters

International Journal of Circuit Theory and Applications, Volume 54, Issue 7, Page 3545-3554, July 2026.
This paper analyzes the impact of quasi‐square wave zero voltage switching (QSW‐ZVS) on passive EMI filter design for DC‐DC buck converters. The extra element theorem (EET) is used to derive the design quantities that ensure converter performance is not altered, and the resulting damping element values are compared with those of traditional converters.

Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

Energy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.
