Abstract:

The problems of evaluating the EMC for capacitor units (CU) in power supply systems are considered. The admissible value of the current non-sinusoidal component for the CU was found, it corresponds to the actual standards. The dynamic model of the «supply line – CU» circuit has been substantiated. An equivalent circuit is given. A non-sinusoidal signal is considered as the sum of a sinusoidal and non-sinusoidal component. As a non-sinusoidal component, a voltage pulse noise model with oppositely polar periodic rectangular pulses and pauses was used. Two approaches to determine the useful signa

Abstract:

Ideally, electric supplying companies are projected to convey sinusoidal voltage having the frequency of constant rate, while the consumers are expected to extract the current in sinusoidal forms with power factor nearly equal to unity. But extensive applications of equipment causing the production of harmonics in domestics and industrial appliances causes some problems in the smooth flow of current and voltage. Especially the usage of non-linear loads is causing the distortion of electric voltage and currents in the power system. Due to these non-sinusoidal flows of voltage and current (harmo

Abstract:

In this paper two input current modulation strategies for matrix converters are experimentally analyzed under two different supply conditions: sinusoidal unbalanced voltages and non-sinusoidal balanced voltages. Both strategies use the Space Vector Modulation (SVM) technique in order to control the matrix converter accordingly to the input and output constraints. Strategy A modulates the input currents keeping the corresponding space vector in phase with the input voltage vector. Strategy B operates in order to keep the input current vector in phase with the positive sequence fundamental compo

When induction motors are powered by solid-state voltage and frequency converters, the torque on the shaft is created by the first harmonic of the current, and the higher harmonics of the cur-rent only create losses in the stator winding.

Nowadays the number of non linear loads in power systems is increasing dramatically. These non linear loads inject harmonic currents and voltage which makes the supply currents non-sinusoidal. These harmonics are eliminated via an active power filter. The reference currents are generated by shunt active filter which is provided to compensate harmonic currents demanded by the load. Different current control strategies are implemented to improve the performance of shunt active power filter. These techniques are useful in making the supply currents sinusoidal.

The modulation strategy of injecting non-sinusoidal into reference voltage is presented in this paper. Z-source inductor current ripple and the relationship of voltage gain versus modulation index are analyzed in detail. Compared to simple boost control, the non-sinusoidal injection modulation strategy can obviously decreased the switching times, thus switching loss is cut down, and the voltage stress and Z-source inductor current ripple are obviously reduced. Theoretical analysis, simulation and experimental results are presented to demonstrate the features of the control.

Abstract:

This study simplifies iUPQC administration by employing a dual three-phase design, which makes the methodology behind the study more transparent. By utilising a parallel (shunt) and series active filter, it is possible to limit the amount of harmonics and unbalances produced by the iUPQC. When compared to a conventional UPQC, an iUPQC modifies the series filter in such a way that it operates as a sinusoidal current source. This is in contrast to a conventional UPQC. Since the iUPQC is regulated using voltage and current sinusoidal references rather than non-sinusoidal references, the frequency

Abstract:

The full-bridge submodule (FBSM)-based modular multilevel converter (FBSM-MMC) offers promising performance due to its ability to output negative FBSM voltage. This paper studies this ability of the FBSM-MMC under zero-sequence voltage injection (ZSVI) and second-order harmonic current injection (SHCI). The focus of the research is to redistribute the FBSM powers by injecting an additional power degree of freedom, resulting in a smaller FBSM capacitor voltage ripple, while keeping the maximum AC output voltage for a given fundamental frequency component of the arm voltage reference.

Abstract:

Non-linear loads in circuits cause the appearance of harmonic disturbances both in voltage and current. In order to minimize the effects of these disturbances and, therefore, to control the flow of electricity between the source and the load, passive or active filters are often used. Nevertheless, determining the type of filter and the characteristics of their elements is not a trivial task. In fact, the development of algorithms for calculating the parameters of filters is still an open question. This paper analyzes the use of genetic algorithms to maximize the power factor compensation in no

Abstract:

This paper presents the high-output-impedance current-mode multiphase sinusoidal oscillators (MSO) using voltage differencing current conveyor (VDCC)-based lossy integrators, which consist of one VDCC, one grounded capacitor, and two grounded resistors. The proposed oscillator can provide an odd-phase and even-phase system without the use of an additional amplifier. The frequency of oscillation (FO) is electronically tuned via the bias current without affecting the condition of oscillation (CO). The proposed oscillator is designed to obtain three-phase sinusoidal waveforms (n = 3). The effect

Abstract:

The aim of the work is the optimisation of a rail heater, constituted by a magnetic core supplied by a sinusoidal current, which induces an eddy current in the rail. Optimisation parameters are electrical and geometrical quantities: supply frequency, voltage amplitude, airgaps, and core shape, while objectives are power transferred to the rail, absorbed current, and power distribution index. Optimisation is performed by an accurate field analysis, provided by the finite element method (FEM), coupled to an automated multiobjective procedure based on fuzzy logic. Particular care has been devoted

Abstract:

For three-phase induction machines supplied by sinusoidal current, it is usual to model the n-bar squirrel-cage by an equivalent two-phase circuit. For a multiphase induction machine which can be supplied with different harmonics of current, the reduced-order model of the rotor must be more carefully chosen in order to predict the pulsations of torque. The proposed analysis allows to avoid a wrong design with non-sinusoidal magnetomotive forces. An analytical approach is proposed and confirmed by Finite-Element modelling at first for a three-phase induction machine and secondly for a five-phas

Abstract:

The parameters of electrical network modes often do not meet the requirements of Russian GOST 32144-2013 and the guidelines of Vietnam. In the actual operating conditions while there is the non-sinusoidal mode in electrical networks voltage and current harmonics are present. Harmonics result in overheating and damage of power transformers since they cause additional active power losses. Additional losses lead to the additional heat release, accelerating the process of insulating paper, transformer oil and magnetic structure deterioration consequently shortening the service life of a power tran

Abstract:

A model for an equivalent electrical circuit designed for a ferrite (3C90) inductor usually used in power converters excited by a non-sinusoidal current appropriate for use in power electronics is proposed. This study, based on 3D finite element analysis, leads to significant precision advantages over 2D analysis for non-symmetric inductors. The frequency range of the analysis for the toroidal core was between 15 kHz and 1 GHz, with different levels of excitation in non-saturation and saturation status focusing on the power loss.

Abstract:

In this paper, power flows in electrical circuits are modelled in a mixed time-frequency domain by using geometric algebra and the Hilbert transform for the first time. The use of this mathematical framework overcomes some of the limitations of some of the existing methodologies, in which the so-called “active current” may not lead to the lowest Root Mean Square (RMS) current under distorted supply or unbalanced load. Moreover, this current may contain higher levels of harmonic distortion compared to the supply voltage. The proposed method can be used for sinusoidal and non-sinusoidal power su
