This paper proposed a new strategy of sinusoidal pulse width modulation (SPWM) technique to control three-phase nine-level switched-capacitor inverter (9LSCI) in grid-connected PV systems. The main advantage of this inverter is high voltage gain, achieved... see more

Many organizations allow GNSS users to access Global Ionosphere Maps (GIMS). However, the TEC estimates derived from GIMs are of insufficient quality to describe small-scale TEC variations over Pakistan. In this paper, the first local TEC map over Pakista... see more

Harmonic analysis is an important application for analysis and design of distribution systems. It is used to quantify the distortion in voltage and current waveforms at various buses for a distribution system. However such analysis has become more and mor... see more

Harmonic is one of sinusoidal components, one wave period from which having multiple frequency of its fundamental frequency one, leading to electrical power quality problems. Harmonic distortion in term of voltage and current ones, generally is due to non... see more

This study aimed to determine the correlation of science process skills with students' creativity in learning of creative problem solving model with an inquiry approach on the simple harmonic motion. The study method that was used is a correlation study b... see more

Pengoperasian beban non linier merupakan penyebab timbulnya harmonisa. Tingkat distorsi atau disebut Total Harmonic Distortion (THD) yang tinggi berpotensi menurunkan kualitas energi listrik yang disalurkan. Dalam penelitian ini dilakukan penguk... see more

The emergence of harmonics caused by electrical loads that are not linear. Input of harmonic current can cause sinusoidal. Content that exceeds the limit can cause poor power quality. The level of harmonic distortion or called Total Harmonic Distortion (T... see more

This study introduces a third order filter and a third order oscillator configuration. Both the circuits use two voltage difference transconductance amplifiers (VDTAs) and three grounded capacitors. By selecting the input and output terminals properly, cu... see more

With advances in energy demand, investments in energy efficiency and power quality are increasingly important. One of the extensively adopted measures is the replacement of fluorescent lamps by LED lamps. This measure contributes to the increase of energy... see more
