Analysis of DC drive fed by single-phase half-controlled converters in sequence control

Separately excited DC motors fed by multistage converters with sequence control are commonly used in mainline traction. The author describes the analysis and performance of a DC drive fed by a two-stage sequentially operated half-controlled converter. The modes of operation of the converter-motor system are identified and a method of performance calculation, taking these modes of operation into account, is presented. The nomograms, and the analytical method of calculating them, are presented for the calculation of an optimum value of filter inductance.<
