Operating modes of single-phase thyristor converter fed dc drives using Phase Angle Control scheme - A monograph

Single-phase thyristor full converter and semi converter fed dc drives with phase angle control scheme have been analysed under all possible modes of operation of continuous and discontinuous armature current conduction. For each case, expressions for the various performance quantities have been presented comprehensively. All the cases have been simulated using power system block set tool box in MATLAB and the simulation results are found to be same as those obtained from the derived expressions. Results obtained on a 220 V, 5 hp separately-excited dc motor operating under all modes of operation, were also in agreement with simulated / calculated values.
