On the Method of Harmonic Balance for Lumped‐Element Transformer Models

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

Towards a Conceptual Integration of Collective Victimization Beliefs and Their Variation Within and Across Contexts: A Q Methodology Study in Five Communities

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Although social psychological research on how people understand collective victimization often examines comparisons between groups’ suffering, studies on related concepts (e.g., collective trauma) suggest numerous other relevant beliefs. The present article aimed to integrate diverse collective victimization beliefs and contribute to their ...
