Abstract

PURPOSE:To accurately decrease the torque ripple of a thyristor motor even in low speed range by controlling armature current with the antiphase signal of the pulsating component of the DC voltage of a motor side converter being added to a current instruction signal. CONSTITUTION:The pulsating component of the DC voltage detection signal of a motor side converter 4 from a DC voltage detector 10 is detected by a current pulsating component instruction circuit 11, the operation of the antiphase signal thereof is performed and DC current pulsating instruction signal is outputted. The sum of the both output signals of a speed control circuit 9 and circuit 11 operating in response to the difference between the outputs of a speed instruction circuit 8 and a speed generator 7 is determined by an adder 12 for obtaining DC current instantaneous value instruction signal. Further, the difference between the actual current detection signal of the detector 13 and the current instantaneous value instruction signal is inputted to an automatic pulse phase shifter 15 via a current control circuit 14 to control the gate signal of the thyristor of a power supply side converter 2.
