Abstract

This paper proposes a reliability analysis model and a power density analysis to evaluate the Solid-State Transformer(SST) topologies for different applications. The solid-state device rating and the redundancy number are considered as two major factors affecting the reliability. In each topology, the optimized selections of these two factors will be determined to reach sufficient reliability. The power density is influenced by the device volume, the transformer volume and the capacitor volume. In terms of these three aspects, the topology which has the highest power density is selected for the certain application. The effectiveness of the model is validated by the comparison between evaluation results and the actual industry products.
