Abstract

The increasing complexity of modern power systems has highlighted the importance of introducing emerging power electronics technologies, such as Solid-State Transformers (SSTs), into undergraduate education. However, SST concepts are often taught at a theoretical level due to limitations in laboratory facilities and the complexity of hardware implementation. To address this challenge, this study proposes the use of LTspice-based digital simulation as an instructional solution for teaching SST concepts in a power electronics course. A quasi-experimental pre-test–post-test research design was employed involving 35 undergraduate students. The instructional intervention integrated conceptual SST explanations with guided LTspice simulation activities focused on switching-level analysis and multi-stage power conversion. Students’ conceptual understanding was evaluated using pre-test and post-test assessments, complemented by a perception questionnaire and analysis of learning artifacts. The results show a substantial improvement in students’ conceptual understanding, as indicated by an increase in mean scores from the pre-test to the post-test. In addition, students reported positive perceptions regarding the usefulness, relevance, and engagement of LTspice-based learning. The findings suggest that LTspice provides an effective and low-cost simulation platform for teaching Solid State Transformer concepts and supports its adoption in undergraduate power electronics education.
