摘要

Circuit protection is a key enabler for future medium-voltage direct-current (MVDC) distribution systems. Hybrid dc circuit breaker (HCB) offers low conduction losses and reasonably fast response times, but suffers from large size. In this paper, a high power density power electronic interrupter design is introduced for the HCB. The device selection and trade-off analysis of voltage clamping circu...
