Based on Matrix Converter-Permanent Magnet Synchronous Machine (MC-PMSM) speed regulator system simulation platform, this paper investigates the behavior and characteristics of MC-PMSM drive system under the condition of MC switch short-circuit faults. Two isolation strategies by utilizing semiconductors and high speed fuses for MC switch short-circuit faults are. Behavior of MC-PMSM drive system during fuse action time under different operating situations is explored. The feasibility of fault-tolerant operat…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
