- New controllable power semiconductor devices make the high frequency pulse-mode operation of the power electronic converters in traction drive systems possible. The capacity and inductance of the converter input filter limiting the ripple of the traction network voltage and current can be decreased for this reason. However, the significant change of the parameter values of these elements can be unacceptable due to necessity to ensure the stable operation of the pulse-mode control system. Results of analytical research, computer-aided simulation and laboratory research concerning stability of the pulse-mode controlled drive system with the electric mining locomotive's traction motor are presented in this paper. On the basis of the traction system simplified model consisting of the energy source, traction network, input filter and drive system, the analysis of system operation was carried out. The non-linear differential equations describing the system were formulated and the points of balance were calculated. The relationships concerning the minimum value of the filter capacity ensuring proper work of the system were obtained on the basis of stability conditions. The waveforms of voltages in the system in stable and unstable working conditions obtained as result of computer simulation using Maple program are shown in the paper. Selected results of laboratory tests of the stability of the traction drive system equipped with the current and speed controllers are also shown here. The specific attention was paid to the influence of the filter capacitor capacity, line resistance and load current on the filter capacitor voltage fluctuations.
