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.

Design and Simulation of a Carrier PWM‐Based Capacitor to Support a Dynamic Voltage Restorer for Voltage Swell and Voltage Mitigation in the Distribution System

Engineering Reports, Volume 8, Issue 7, July 2026.
This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (
