一种基于混合器件的双向中压直流固态断路器

The mixture unidirectional solid-state circuit breaker (SSCB) based on transistor-based devices [i.e., IGBT-based line commutation switch (LCS)] and the thyristor-based devices can combine their respective advantages, however, the conduction loss and cost may increase significantly when expanding to a bidirectional topology because the number of IGBTs had to be doubled with the expansion of unidir...
