Journal ArticleDOI
Space-Vector-Modulated Three-Level Inverters With a Single Z-Source Network
TL;DR: This paper presents the control of a Z-source neutral point clamped inverter using the space vector modulation technique, which enables the operation of the Z- source arrangement to be optimized and implemented digitally without introducing any extra commutations.
Journal ArticleDOI
Semiconductor Devices in Solid-State/Hybrid Circuit Breakers: Current Status and Future Trends
TL;DR: In this paper, the current status for solid-state circuit breakers (SSCBs) as well as hybrid-circuit breakers with semiconductor power devices is reviewed.
Journal ArticleDOI
