“…6,7 During the past decades, great efforts have been made to improve the moving speed of the contacts of HSS in order to maintain insulation and withstand the breaking over voltage as fast as possible after the current is commutated. 8,9 Until recently, numerous proposals for DC hybrid circuit breaker designs with HSS combined have been widely developed for the sake of fast and reliable breaking. [10][11][12] Yet, as is known, it is difficult to fulfill fast current commutation only by depending on arc voltage of HSS.…”

Articles you may be interested inInvestigation on critical breakdown electric field of hot sulfur hexafluoride/carbon tetrafluoride mixtures for high voltage circuit breaker applications A new design of DC hybrid circuit breaker based on high-speed switch (HSS) and arc generator (AG), which can drastically profit from low heat loss in normal state and fast current breaking under fault state, is presented and analyzed in this paper. AG is designed according to the magnetic pinch effect of liquid metal. By utilizing the arc voltage generated across AG, the fault current is rapidly commutated from HSS into parallel connected branch. As a consequence, the arcless open of HSS is achieved. The post-arc conducting resume time (∆t c ) of AG and the commutation original voltage (U c ), two key factors in the commutation process, are investigated experimentally. Particularly, influences of the liquid metal channel diameter (Φ) of AG, fault current rate of rise (di/dt) and U c on ∆t c are focused on. Furthermore, a suitable U c is determined during the current commutation process, aiming at the reliable arcless open of HSS and short breaking time. Finally, the fault current breaking test is carried out for the current peak value of 11.8 kA, and the validity of the design is confirmed by the experimental results. C 2015 AIP Publishing LLC.

“…Therefore, the conduction losses are dominating [2]. However, augmenting the solid state switch with an ultra-fast mechanical bypass switch, similar to the concepts laid out in [4], may further reduce on-state losses significantly. Maximum blocking voltages of today's semiconductors are considerably less than those required for medium voltage systems.…”

“…In this sense, a solid state fault isolation device (FID) serves the dual purpose of a recloser and sectionalizer. It has already been proven that the usage of power semiconductor devices can mitigate short circuit currents and voltage sags during a short circuit event [1]- [4]. In this paper, we first illustrate the need for ultra fast fault isolation in power electronic based systems by comparing typical system responses to simulated faults in conventional and power electronics based systems.…”

This paper addresses the timely issues of modeling of, and defining selection criteria for, a solid state fault isolation device (FID) to be used in power electronic based distribution systems (PEDS). Circuit interruption requirements and FID location in power electronics based distribution system are discussed in this paper. The paper subsequently derives the FID parameters by mapping the characteristics of a conventional medium- voltage distribution system onto that of the PEDS envisioned under a new multi-university Engineering Research Center funded by the National Science Foundation. A design of a high frequency solid state transformer (SST) is presented and evaluated. An average-value simulation model of a SST, as the interface of the PEDS to the legacy system, is used to derive key parameters of the FID. The simulation and experimental results validated the feasibility of the proposed FID topology. Finally, the conceptual Power Hardware-in-the-Loop simulation setup for testing the FID under various system conditions is presented.Index Terms-Solid state circuit breaker, power electronics based distribution system.

Three generations of medium voltage fault isolation devices (FID) for a power electronics based distribution system, the FREEDM System, are reported in this paper. In the Gen-I FID, three 6.5 kV silicon IGBTs are series connected to achieve 15 kV class distribution voltage blocking capability. Whereas in the Gen-II and the Gen-III FIDs, 15 kV Silicon Carbide (SiC) ETO devices are used. Since one single such device can meet the voltage withstand requirement, the operation losses as well as dimensions are significantly reduced. Future improvements in the Gen-III FID include the use of hybrid schemes and the development of symmetrical blocking high voltage SiC devices to further minimize the operation losses.Index Terms-fault isolation device, solid state circuit breaker, hybrid circuit breaker, SiC device, Emitter turn off thyristor, distribution system protection.
