Simulation of passive filter design to reduce Total Harmonic Distortion (THD) in Energy-Saving Lamps (LHE) and Light Emitting Diodes (LED)

Autor: F Susanto, E M Silalahi, S Stepanus, B Widodo, R Purba

Publikováno v: IOP Conference Series: Earth and Environmental Science. 878:012059

This paper discusses the design of a passive filter system for Energy-Saving Lamps (LHE) and Light Emitting Diodes (LED) using the MATLAB Simulink software. This type of lamp is a type of non-linear load that produces harmonics of current and voltage

Reducing of total harmonic distortion by simulating passive filters to suppress harmonic currents with the case: Faculty of Engineering Building, Universitas Kristen Indonesia Jakarta

Autor: R Purba, B Widodo, S Stepanus, A D T Prasetyo, E M Silalahi

Publikováno v: IOP Conference Series: Earth and Environmental Science. 878:012060

Today’s electrical appliances use power electronics to save electricity. However, this equipment generates non-sinusoidal current, causing wave defect, expressed as total harmonic distortion (THD). As the %THD increases, the greater risk of equipme
