Improving Compensation Performance in Three-Phase Active Power Line Conditioners by DC-Voltage Control
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2014, Vol 21, Issue 3
Abstract
This paper analyses the influence of the prescribed DC-link voltage on the filtering efficiency, in terms of current harmonic distortion after compensation, in a three-phase three-wire shunt active power line conditioner. The AC voltage controller as nonlinear load and two configurations of the coupling filter are taken into consideration. It is pointed out that, for each rms current to be compensated, there is an optimal set value of the DC-link voltage which minimizes the supply current distortion after compensation. Experimental tests validate the simulation results.
