Energy Science &Engineering, Volume 13, Issue 12, Page 6221-6234, December 2025.18‐pulse AC/DC converter with T‐connected autotransformer for feeding VCAMD. ABSTRACT Reducing harmonics in alternating current (AC) input and ripples in direct current (DC) output enhances power quality, achievable through multi‐pulse converters (MPCs). This study presents the design, simulation, and analysis (in MATLAB/Simulink) of an autotransformer‐

Teaching, research, and everything in between: An autoethnographic account of academic identity
Review of Education, Volume 13, Issue 3, December 2025.Abstract This analytic autoethnography offers a critical and personal reflection on two decades (2005–2025) of academic life at a South African university. Framed within South Africa's shifting higher education landscape, the study explores academic identity formation through eight thematic lenses: from early experiences as an unprepared lecturer to ...
