Lektrokom : Jurnal Ilmiah Teknik Elektro, 2020 Abstract. Along with the rapid development of power electronics technology which is also useful for saving electrical energy. This technology is also used in lighting such as energy saving lamps (LHE) and light-emitting diode (LED). However, LHE and LED are non-linear loads that cause electrical power quality problems, namely producing voltage ...

Power Quality Improvement by Reduction of Total Harmonic Distortion (THD) using PWM Inverter
International Journal of Innovative Technology and Exploring Engineering, 2019 In this paper, a PWM inverter is proposed for improvement of power quality i.e., reduction of total harmonic distortion (THD). The power quality problems reduce the lifetime and performance of equipments. The proposed system reduces the THD which is generated from the nonlinear loads.

Turkish Journal of Computer and Mathematics Education (TURCOMAT), 2021 These harmonics are higher than essential frequencies and cause Total Harmonics Distortion (THD) which increases the rms current and generates more warmth in the load. Numerous techniques are used to suppress the harmonics to limit the warmth in the load.
