SiC MOSFET固态断路器关键技术研究OA

With the development of smart distribution grids,circuit breakers provide strong protection for the safety of distribution grids.It focuses on the key technologies of solid-state circuit breaker(SSCB)based on SiC MOSFETs.By integrating wide bandgap semiconductor materials and intelligent optimization algorithms,it enhances the performance of SSCBs,which can solve the problems of slow response speed,short service life and arc presence of traditional mechanical circuit breakers.It constructs a test platform to verify the prototype.The results show that the prototype can achieve rapid circuit breaking,with an identification accuracy error of no more than 0.5 ms,a working life exceeding one million times,and all core parameters meet the requirements of industry standards.
