Improved power supply performance of vibratory conveyor drives

Abstract

A practically realized solution of a power supply for vibratory conveyor drives is presented. The solution is an improvement from the quality of electrical energy point of view. An analysis is given of the AC/DC converter used as the input active filter serving for reduction of the undesired higher harmonics of the input (network) current and improvement of the power factor. The experimental results are presented together with an analysis of the characteristic waveforms (oscilloscopic records of the network voltage and current) at steady state, obtained by the realized converter.
