The effect of variation of nonlinear load on power factor of the ac supply network

Abstract EN

The aim of this paper is to evaluate the effect of the converter system on the power factor of the supply network.

Therefore a 3-phase, 6-pulse , bridge converter is assembled and connected to a power supply through a 3-phase ac voltage regulator.

The theoretical analysis is simulated using Fourier series analysis and Fast Fourier Transform (FFT) algorithm.

The experimental measurements of distortion factor, displacement factor and total power factor are recorded.

The experimental results are shown to be coincident with the theoretical results.

The consideration of power factor improvement relative to distortion and displacement factors is discussed.
