Multi-port Hybrid HVDC Circuit Breaker

, 2017
This paper proposes a new n-port hybrid dc circuit breaker for offshore multi-terminal HVDC grid application. The n-port dc circuit breaker can substitute n-1 hybrid dc circuit breakers at a dc bus with n-1 adjacent dc transmission lines.

Design and Analysis of a Controllable Reactor Solid-State Circuit Breaker for Enhanced Fault Current Interruption in AC/DC Microgrids

Energies
The occurrence of short-circuit faults in AC/DC microgrids gives rise to exceptionally high currents with rapid escalation, particularly in DC feeders where current zero-crossing is absent.

Design and Experimental Tests of a Superconducting Hybrid DC Circuit Breaker [PDF]

, 2018
Direct current (DC) circuit breakers are a key ena-bling technology for fault management in multi-terminal high voltage direct current (HVDC) systems. DC fault isolation is chal-lenging due to the high rate of rise of the fault current and the lack of ...

Non‐Volatile Silicon Mach‐Zehnder Switches with 0.7 π Phase Shift Based on Graphene Heaters and Sb2Se3 Phase Change Material

Advanced Optical Materials, EarlyView.
ABSTRACT Photonic integrated circuits (PICs) can deliver unparalleled performance for future neuromorphic computing applications. Such neuromorphic PICs require a large number of tunable switches, which are typically realized with current‐controlled heaters, resulting in considerable energy consumption.

Optimized algorithm of active injection circuit to calibrate DC circuit breaker

International Journal of Electrical Power & Energy Systems, 2018
Abstract The widely acknowledged high-voltage direct current (HVDC) technology has now been accepted as a solution of connecting renewable energy sources. However, this technology is vulnerable when facing DC-side faults; due to the low DC impedance, the fault current can rise to an extremely high value in a short time.

Pharmacologic Modulation of ARID3A with Rimegepant Reactivates Type I Interferon Signaling and Sensitizes Triple‐Negative Breast Cancer to PD‐1 Blockade

Advanced Science, EarlyView.
This study identifies ARID3A as a key immunosuppressive transcription factor in TNBC. Its inhibition activates the type I IFN pathway, boosting CD8+ T cell infiltration and sensitizing tumors to anti‐PD‐1. The FDA‐approved migraine drug Rimegepant targets ARID3A, enhances immunotherapy efficacy in preclinical models, and establishes a druggable axis to
