The most popular and best modulation method used among Pulse Width Modulation (PWM) technique is Space Vector Modulation (SVM) method. SVM generates low Total Harmonic Distortion (THD) and it is well suitable for motor control. Harmonics is one of the major power quality issues occurring in most of the application. SVM holds the major advantage that only one switch is turned on at a time. The p...

Power quality standards (IEEE-519) compel to limit the total harmonic distortion (THD) within acceptable range caused by rapid usage of power electronic equipment. This paper envisages on the simulation of instantaneous active and reactive theory based shunt active filter with MATLAB/ Simulink, as a better solution for reduction of the harmonics.

The quality of voltage and current delivered by the power utilities has become a major concern of the modern industries. These power quality problems are voltage sag and harmonic which can cause problems to the industries ranging from malfunctioning of equipments to complete plant shutdowns. In this paper, the proposed Quality Power Provider (QPP) modeled by simulation is able to compensate the...

This work presents a method capable of designing power filters to reduce harmonic distortion and correct the power factor. The proposed method minimizes the designed filters’ total investment cost such that the harmonic distortion is within an acceptable range. The optimization process considers the discrete nature of the size of the element of the filter. This new formulation is a combinatoria...

The paper presents the new C-type high harmonic power filter design process whose aim is the reduction of total harmonic distortion in an industrial power supply system. A new method for C-type filter design is proposed and an example of the method application to an industrial plant is provided. The basis for the new algorithm is assuming, at the design phase, the required distribution of the h...

In evaluating the quality of waveform energy, Total Harmonic Distortion can be one of the unique testing parameters showing the disturbance effect on pure waveform or regenerated waveform. As harmonics may added to distort the fundamental waveform, the analysis of signal dynamic characteristic and the measurement of harmonics effect on the integrity of the waveform will be study to explore and ...

This report is a documentation of analytical techniques for characterizing the degree of nonlinearity implicit to active networks designed to achieve nominally linear performance input -tooutput performance characteristics. It addresses such metrics as total harmonic distortion, intermodulation levels, intercept points, and spurious free dynamic range. Aside from addressing the theoretic nature...

A new architecture of simple low voltage BiCMOS fourquadrant multiplier is proposed and analyzed. It operates with ±1.5V power supplies and 3Vp-p fully input signal swings. Simulation results based on AMS 0.8μm n-well BiCMOS process parameters are given to verify the theoretical analysis. The architecture of four multipliers typically have a nonlinearity error less than 1% over ±1.5V input rang...

This paper describes the design of a low-voltage translinear second-order quadrature oscillator. The circuit is a direct implementation of a nonlinear second-order state-space description and follows from a recently developed synthesis method for dynamic translinear circuits. It comprises only two capacitors and a handful of bipolar transistors and can be instantaneously controlled over a very ...

A class-AB four-quadrant current multiplier constituted by a class-AB current amplifier and a current splitter which can handle input signals in excess of ten times the bias current is presented. The proposed circuit operation is based on the exponential characteristic of BJTs or subthreshold MOSFETs. The multiplier is designed using the latter devices and achieves very low power consumption.
