On the Application of Thévenin Equivalent Circuits to the Analysis of Vacuum Tube Circuits
Electronics, 2023 In this paper, we express Thévenin equivalent circuits seen looking into the terminals of the small-signal model of the vacuum tube triode in terms of the Thévenin equivalent circuits seen looking out of the other terminals and apply them to the analysis

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 ...

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.

A Novel Digital Twin Platform for Accelerating Power Systems Restoration
Energy Internet, Volume 3, Issue 2, Page 111-141, July 2026.Hardware Architecture Design of DT System in Laboratory. ABSTRACT With the global energy structure transforming towards the goal of net zero emissions, the penetration of an inverter‐based resource (IBR) in power systems is increasing. This transformation poses two critical challenges: the system post blackout restoration process becomes extremely ...
