Redundancy design of modular DC solid-state transformer based on reliability and efficiency evaluation

The modular DC solid-state transformer (DC-SST) is promising but restricted by limited reliability, which can be solved by redundancy. However, current redundancy designs are only based on the reliability evaluation in stable operation condition and seldom efficiency. In this paper, a redundancy design method of DC-SST is proposed considering both reliability and efficiency. The long-term mission ...
