A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems
Advanced Science, Volume 13, Issue 42, 28 July 2026.A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

Using an Evolutionary Algorithm for Harmonic Load Modeling by Norton and Thevenin Equivalents.
International journal of electrical and computer engineering systems, 2014 The Norton equivalent model for harmonic load modeling is used widely. The parameters of the model are usually calculated analytically. These calculations are based on measured or simulated voltage/current waveforms. In this case, harmonic analysis is needed to obtain the harmonic spectra. After this step, model parameter values are calculated for each

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.

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 (
