Research ArticleOpen accessIn the abstractMathematical Model of 4-Quadrant DC Electric Drive with 6-Pulse Dual ConverterKosmas ZdrozisMathematical model simulating the operation of DC electric drive hoisting mechanism has been developed. The study illustrates the capabilities of the developed model for investigation both normal and abnormal modes of operation of the converter and the supplying voltage. Large attention was given to the thyristor converter and its firing system so that fast-proceed micro-processes occurring in the converter can … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,001 accessesView PDFCite
