ANALIS PENGUKURAN DAN PERHITUNGAN TOTAL HARMONIC DISTORTION (THD) PADA BEBAN NON LINIER
Jurnal Sains & Teknologi Fakultas Teknik Universitas Darma Persada, 2022Harmonisa mengakibatkan terjadinya distorsi gelombang arus dan tegangan. Harmonisa terjadi karena adanya beban non linier, dimana akan terbentuk gelombang yang berfrekuensi tinggi yang merupakan kelipatan dari frekuensi fundamentalnya. Frekuensi harmonik yang lebih tinggi daripada frekuensi operasi memiliki efek mengurangi efisiensi atau menyebabkan ...

Predicting total harmonic distortion (THD) in ADSL transformers using behavioural modeling
Proceedings of the 2003 IEEE International Workshop on Behavioral Modeling and Simulation, 2004As a design application, the ADSL broadband line transformer offers interesting challenges somewhat different to those in power supply design. The aspect of total harmonic distortion (THD) as affected by the nonlinear behaviour of the magnetic material in a line transformer is analysed using simulation.

A Cost Effective Method of Reducing Total Harmonic Distortion (THD) in Single-Phase Boost Rectifier
2007 7th International Conference on Power Electronics and Drive Systems, 2007Due to its simplicity, the discontinuous conduction mode boost rectifier is potentially the least expensive active line-harmonics reducing circuit. The line current however, shows considerable distortion when the peak input voltage is close to the output voltage. This paper proposes a simple, low-cost method to reduce the line harmonics.

Integrating renewable energy resources especially photovoltaic systems with microgrids has become an unavoidable choice for most countries and in Egypt the government has this ambition to reach a percentage of 20% of the total national electricity generation from solar energy. Which in turn bring some challenge to the electrical utility operator.

A nonlinear system determines the quality of power under closed and open control. An issue with power is overcome by a three-phase DC/AC embedded DC/DC ZETA converter with proposed Hysteresis Current Controller (HCC). In this proposed system, personal computers are operated in order to record harmonic generation.
