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

Abstract:
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. The purpose of the work is to develop a methodolo-gy for determining the permissible mechanical load of asynchronous motors at non-sinusoidal currents. To achieve this goal, it is necessary to determine the influence on the mechanical pow-er of the motor of higher current harmonics, the effective values of which depend on the control parameters of semiconduct

Permanent magnet brushless dc (PMBDC) and synchronous machines (PMSM) drives are favored in variable speed applications for their high efficiency operation. Energy efficiency improvement in such motor drives is of interest in recent times because of rising cost of energy. Accordingly, two current control options for improving efficiency of these drives are taken for study and they are; (i) injecting sinusoidal and non-sinusoidal currents in PMBDC machines and (ii) lowering switching frequency of inverter driving the PMSM but without having significant low ordered sidebands of currents.

A moment-method formulation is developed, using two-dimensional basis functions to represent the total non-uniform surface current distribution over the surface of the wire of the helix.
