Studi Watak Harmonik pada Rectifier dalam Kondisi Berbeban dan Tanpa Beban
Abstrac: A power electronic
equipment that is used for the aplication of drive system in industry to
control direct current voltage, is a nonlinear load and a harmonic source.
Refer to the nonlinear characteristic of solid state power convertion
equipment, harmonic current will be injected in the power system, making
voltage harmonic distortion. The goals of this research are to know the
characteristics of current and voltage harmonic, to analyze of curent and
voltage total harmonic distortion, and to determine the parameters of low passpassive
filters that will be used to decrease the harmonic current and voltage in the rectifier.
This research was done experimentaly by three observation conditions at laboratory,
namely by changing the voltage of output at the condition of loaded andnonloaded,
and to change load current of rectifier. The results of this reseach showed
that under noload condition the highest harmonic voltage was found at the third
order of harmonic, and for the highest harmonic current accured at the fifth
order of harmonic, with the highest value of voltage and current total harmonic
distortion 3,092% and 45,32%. Under load condition the highest harmonic voltage
was found at the fifth order ofharmonic, and for the highest harmonic current
on second order of harmonic, with the highest value of voltage and current
total harmonic distortion 2,850% and 67,23%. Under changing load current
condition the highest harmonic voltage was found at the fifth order of
harmonic, and for the highest harmonic current on second order of harmonic,
with thehighest value of voltage and current total harmonic distortion 2,680%
and 44,02%.
