In this paper, a parallel arrangement of a silicon MOS-gated thyristor structure and a silicon carbide Power MOSFET is proposed and experimentally demonstrated for the first time. Experimental results show that the hybrid switch exhibits low conduction losses at low current levels as well as large current-carrying capability at high current levels. In addition, compared to Clustered IGBT structure,...
The rapid development of cloud computing has raised big concerns over the high energy consumption of modern data centers. To satisfy the ever increasing data traffic needs, the energy consumption of data center network (DCN) also takes a significant proportion. The newly emerging technology, Software Defined Networking (SDN), which allows flexible control of network devices, brings a new opportunity...
Software Defined Networks (SDN) emerged as a new network paradigm to address the customization and flexibility problems in traditional computer networks. In SDNs, a logical centralized programmable controller manages the whole networks by installing rules onto switches. It is widely regarded that one controller is restricted on both performance and scalability. To address these limitations, pioneering...
In this paper, we demonstrated an optical lithium niobate sensing chip (LNSC) by integrating an optical waveguide phase modulator and an evanescent field-based waveguide sensor on the same chip. The repeatable phase measurements based on a homodyne metrology are achievable by injecting evaporative ethanol (concentration: 95%) liquid onto the surface of sensing transducer. The proposed sensing chip...
