A novel modification of the Z-source circuit breaker topology is presented for low voltage applications. An ultra-fast mechanical switch has been used in place of the solid-state switch (thyristor) in the Z-source circuit breaker to reduce the energy loss utilizing the very low resistance of mechanical contactors. The proposed modification also facilitates bi-directional current flow for distributed...
A novel modification to Z-Source DC circuit breakers has been proposed to reduce power consumption from its predecessor significantly. The power thyristor serves as the means of circuit isolation and voltage blocking in the event of a fault in traditional Z-Source DC circuit breakers. However, Z-Source circuit breakers direct full load current through the Thyristor. The resulting voltage difference...
This paper presents a novel class of quasi-Z-source galvanically isolated DC-DC converters intended for the integration of low voltage renewable energy sources into a DC microgrid. These converters combine characteristics of the transformer based and the inductor based impedance-source galvanically isolated DC-DC converters. They feature the continuous input current essential for photovoltaic applications...
