This paper deals with the issues of computation nonlinear load harmonic currents in presence external distortions based on real measurements help passive harmonic. Such values are necessary when modeling an equivalent as current sources distortions. The filter allows to separate and internal distortions, which is determining a single consumer. influence various parameters load, such filter, imp...

-In this paper, comparative evaluation of different techniques for harmonic reduction in input current of ac-dc converter is presented. Converters employing ac side switching, resonant converter, active clamped boost converter are simulated in PSIM and their performance under varying load condition with load voltage regulation is evaluated. The results revealed that active clamped boost convert...

Algorithms for ground vehicle classification using acoustic measurements often use features based on the relative amplitudes of harmonic components. The average power measured at each harmonic frequency fluctuates due to scattering of the acoustic waves during propagation and additive noise at the sensor. In this paper, we use propagation models for frequencydependent scattering of acoustic sig...

A third order harmonic oscillator has been proposed based on the resonant tunneling diode pair oscillators. This oscillator has significant advantages, good stability of the oscillation frequency against the load impedance change together with capability to output higher frequencies. Proper circuit operation has been demonstrated using circuit simulations. It has been also shown that the output...

Induction motors (IMs) are commonly used in various industrial applications. To improve energy consumption efficiency, a reliable IM health condition monitoring system is very useful to detect IM fault at its earliest stage to prevent operation degradation, and malfunction of IMs. An intelligent harmonic synthesis technique is proposed in this work to conduct incipient air-gap eccentricity faul...

Short Abstract—A simplified inverse class F power amplifier (PA) with a voltage second harmonic peaking and third harmonic short operating at 2.14GHz for WCDMA base station applications has been developed. The load network is based on transmission line harmonic traps and provides high impedance at the second and low impedance at the third harmonic to the PA. The PA uses a packaged Silicon LDMOS...

Power system transmission and distribution utilities strive to ensure that the voltage harmonic distortion planning levels are maintained by limiting the harmonic currents injected by the loads. With large customers assessment of the harmonics contributed is carried out at the point of common coupling (PCC). Determination of the contribution to the overall harmonic distortion at the PCC by the ...

Indian electrical industries supply alternators for rectifier loads, arc furnace loads and thyristor load applications to various customers. In such cases the generator line currents are not sinusoidal but are like trapezoidal which are due to harmonics .They may cause problems for utilities and industrial power system. Single tuned (ST) filter is the most commonly used device for both harmonic...

This article is a study on the analysis of harmonics reductions and load voltage control for Vienna Rectifier (VR) with help of the Triplen Harmonic Injection (THJ) and the proportional integral controller (PIC). The sinusoidal PWM is the easiest modulation technique for AC-DC rectifiers to comprehend; however, it is not capable of entirely using the accessible DC bus source voltage. In order t...

Industrial Static Var Generator (SVG) is typically applied at or near the load center to mitigate voltage fluctuation, flicker, phase unbalance, non-sine distortion or other load-related disturbance. Special attention is paid to the influence of grid voltage quality on SVG current, the non-sine distortion and unbalance of grid voltage causes not only the AC current distortion and unbalance but ...
