Patent Research of DC Electric Drive Power Supply Systems Based on Active Converters With Power Correction

Abstract

Despite the fact that the AC electric drive has recently been increasingly “displacing” the DC drive, it is quite relevant, because completely satisfies the requirements of technological processes. Consideration of the problem of electromagnetic compatibility of DC converter installations with the supply electrical network occupies a large place. The article provides research and analysis of the influence of valve loads on the quality of the power supply network and ways to improve the quality of power supply by replacing existing converters with active DC-DC converters with power factor correction, as well as a patent study.
