We report the results of a Floquet analysis of two-dimensional arrays of resistively and capacitively shunted Josephson junctions in an external transverse magnetic field. The Floquet analysis indicates stable phase locking of the active junctions over a finite range of values of the bias current and junction capacitance, even in the absence of an external load. This stable phase locking is rob...

This paper presents a novel three-phase four-wire low power rating flexible hybrid active filter with a power factor, harmonic and neutral currents capability for distribution systems. The passive filter is tuned to compensate the two largest harmonics components and the power factor of the load. A selective algorithm is employed in order to enable the active filter to compensate only the desir...

Author Affiliation: Institute for Power, Electronics and Telecommunications Engineering, Faculty of Engineering, University of Novi Sad, Novi Sad, Yugoslavia. Abstract: The aim of this letter is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner (UPQC), which is extended by adding a shunt active filter at the load side. Its main purpose...

The harmonics due to using of nonlinear industry loads based on power electronic elements have resulted in enormous economic loss. Therefore, the power utilities always need new technologies to deal with the harmonic problems. Active power filter (APF) has been considered as an attractive solution due to its effective performance for harmonic mitigation. The compensation currents injected by th...

The inrush currents of transformers are among the main causes which compromise performance protection relays in practice. Therefore, discrimination between and faults is very important. A new technique proposed this paper to distinguish internal fault other normal transient conditions (such as current). Accordingly, a operational characteristic defined for feature extraction classification inst...

The goal of this study was to determine the effects of the L-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fKv1.4ΔN), an N-terminal-deleted mutant of the ferret Kv1.4 potassium channel. Measurements were made using a two electrode voltage clamp technique with channels expressed stably in Xenopus oocytes. The fKv1.4ΔN currents displayed...

An input/output feedback linearization control strategy is developed for control of three-level three-phase neutral-point-clamped rectifier using its dual Lagrangian modeling. The load current of the rectifier can be given in two forms: (i) the load current involving the current of capacitor C1 (ii) the load current involving the current of capacitor C2. Applying the obtained load current to th...

The uptake of electric vehicles (EV) is increasing every year and will eventually replace the traditional transport system in near future. This imminent increase urging stakeholders to plan up-gradation power infrastructure. However, for efficient planning support an additional load, accurate assessment vehicle load quality indices required. Although several EV models estimate charging profile ...

The circulating currents of a modular multilevel converter (MMC) are ideally assumed to be the sum of an ac component and dc ac component operating with fundamental frequency. However, as ac current flows through the submodule (SM) capacitors, the capacitor voltages fluctuate with time. Consequently, the circulating current is usually distorted and allows multiple frequency components with the ...
