TY - JOUR AU - Zdrozis, Kosmas PY - 2005 TI - Mathematical Model of 4-Quadrant DC Electric Drive with 6-Pulse Dual Converter JF - American Journal of Applied Sciences VL - 2 IS - 5 DO - 10.3844/ajassp.2005.1025.1027 UR - https://thescipub.com/abstract/ajassp.2005.1025.1027 AB - Mathematical 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 be simulated with a high degree of accuracy.
