“…In parallel, from 2010 and 2014 a slightly different SSCB approach is developed using SiC Static Induction Transistors (SIT), which have similar structure to normally-on JFET but smaller channel length, offering less conduction resistance and higher blocking voltage capabilities [9]. 400Vdc power distribution for data centres was the main application.…”

“…The SSCB takes approximately 10 µs to respond to a short circuit fault. A SSCB using SiC static induction transistors (SITs) was investigated for 400V DC data center distribution systems in [21] [22]. SITs, which have the same structural configuration as JFETs except for a much shorter channel length, offer ultralow on-resistance.…”

Short circuit protection remains one of the major technical barriers in DC microgrids. This paper reviews state of the art of DC solid state circuit breakers (SSCBs). A new concept of a self-powered SSCB using normally-on wideband gap (WBG) semiconductor devices as the main static switch is described in this paper. The new SSCB detects short circuit faults by sensing its terminal voltage rise, and draws power from the fault condition itself to turn and hold off the static switch. The new two-terminal SSCB can be directly placed in a circuit branch without requiring any external power supply or extra wiring. Challenges and future trends in protecting low voltage distribution microgrids against short circuit and other faults are discussed.

“…As a result, dc circuit breakers must have high-speed interruption performance within 10 ms [4,5]. DC circuit breakers are divided by design into mechanical devices [6][7][8], semiconductor devices [9,10], and hybrid devices [11][12][13][14][15].…”

SUMMARYThis paper presents a new hybrid dc circuit breaker producing no conducting power loss under normal operating conditions and having the capability to interrupt a large amount of short-circuiting current within several milliseconds. It consists of two reactors for current limiting and current control, two mechanical contactors, and a multilevel converter based on the cascade connection of multiple fullbridge dc/dc converter cells. It is characterized by achieving current commutation from the main mechanical contactor to the multilevel converter with fast current control. This results in eliminating auxiliary power semiconductor switches that produce a nonnegligible conducting power loss under normal operating conditions. This paper discusses both principles of operation and control method of the new hybrid dc circuit breaker. Experimental verification is performed by a downscaled system rated at 300 V and 150 A, along with verification by computer simulation.
