Abstract:High-voltage direct-current (HVDC) rated at 270 Vdc is one of the main power supply technologies expected for future more electric aircraft (MEA). However, dc protection is still one major challenge preventing the wide deployment of HVDC. To overcome this, Z-source solid-state circuit breakers (Z-SSCBs) could be employed due to their simple structure and fast speed of response. However, Z-SSCBs alone cannot effectively isolate a short-circuit fault when a large fault resistance and a small fault current ramp r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
