Energy consumption for ion transport in a segmented Paul trap [PDF]
There is recent interest in determining energy costs of shortcuts to adiabaticity (STA), but different definitions of "cost" have been used. We demonstrate the importance of taking into account the Control System (CS) for a fair assessment of energy ...

Coupling Matrix Representation of Nonreciprocal Filters Based on Time Modulated Resonators [PDF]
This paper addresses the analysis and design of non-reciprocal filters based on time modulated resonators. We analytically show that time modulating a resonator leads to a set of harmonic resonators composed of the unmodulated lumped elements plus a ...

Prony Analysis for Power System Transient Harmonics
Proliferation of nonlinear loads in power systems has increased harmonic pollution and deteriorated power quality. Not required to have prior knowledge of existing harmonics, Prony analysis detects frequencies, magnitudes, phases, and especially damping

The condition monitoring of the passive harmonic filters in rail way DC sub stations [PDF]
The condition monitoring of the passive 12th and 24th harmonic filters in the DC sub station employing 12 pulse passive rectification plays the vital role of suppressing generated harmonics. The railway service of South Africa (Transnet) is confronted by

The new 150 MVAr, 18 kV static var compensator for SPS: background, design and commissioning [PDF]
A new Static Var Compensator (SVC) was designed, installed and commissioned by ABB for CERN’s Super Proton Synchrotron (SPS) accelerator. Due to the sensitive nature of the pulsating power converter load for the SPS magnets, very strict requirements were

A Two-stage approach to harmonic rejection mixing using blind interference cancelling [PDF]
Current analog harmonic rejection mixers typically provide 30–40 dB of harmonic rejection, which is often not sufficient. We present a mixed analog-digital approach to harmonic rejection mixing that uses a digital interference canceler to reject the ...
