Abstract

The aim of this paper is to analyze the influence of adding serial inductance in AC side of the ‎‎3ph -6 pulse bridge rectifier on the reduction of harmonic distortion rate. A simulated model ‎with serial inductance was analyzed. The 3-phase 6-pulse diode bridge rectifier was chosen ‎because it corresponds to the operation of the 6-pulse thyristor bridge rectifier at maximum ‎load (while keeping the angle α = 0). Both the total harmonic distortion (THDi) and the ‎power factor (PF) for the circuit have been measured. The results obtained of the THDi has ‎been recorded for four values of serial inductance and results was compared with the (IEEE 519-1992) standard. Comparison results indicates ‎that for values of inductive reactance (Xi) up to 67% cause a reduction of THDi which is above the standard values, while for (Xi) more than 67% cause a reduction in THDi within the acceptable standard level. Analyzing of results prove that the adding of serial inductance at the AC ‎side leads to good reduction in harmonic distortion rate, but with some reduction in power ‎factor value, which results in some energy losses.
