Network-on-chip (NoC) architectures are fast becoming an attractive solution to address the interconnect delay problems in chip multiprocessors (CMPs). However, increased power dissipation and limited performance improvements have hindered the wide-deployment of NoCs. In this paper, we combine two techniques of adaptive channel buffers and router pipeline bypassing to simultaneously reduce power consumption...
Ultrafast self-switching of spectral-amplitude-encoded 40 Gb/s DPSK signals is demonstrated for the first time. Switching between 21 ports with 15 nm maximum bin separation is achieved using a single correlator based on HNLF and an AWG.
This paper compares the performance and material costs of two candidate tubular permanent magnet topologies, viz., quasi-Halbach magnetized moving magnet and flux switching (moving-iron) machines for applications in active vehicle suspension. Both machines are optimally designed for the same operating conditions and under the same volumetric and thermal constraints. It is shown that while the flux...
This paper evaluates switching and conduction losses of a direct AC fed converter for switched reluctance machine drives. The commutation process of the converter employing space vector modulation is analyzed, and the switching losses associated with ldquohardrdquo turn-on and ldquohardrdquo turn-off events are quantified based on experimentally validated device characteristics. It is shown that for...
This paper proposes an N-phase, AC fed, switched reluctance drive for aerospace applications. The proposed converter is capable of direct AC conversion and eliminates the unreliable DC link capacitor present in conventional DC supply converters. It is shown that, by space vector modulation of output current, control of active and reactive power can be achieved whilst three sinusoidal AC input phase-currents...
Single-pole tripping of circuit breakers at the end of a transmission line for clearing LG fault (single phase to ground fault) produces high negative sequence current in nearby generators. Inserting a capacitor-connected between the ground and neutral of wye winding of a transformer at the end of the transmission line under open phase conditions-causes the net zero sequence reactance, which shunts...
