Abstract
PURPOSE:To enable to shorten the wasteful switching time irrespective of load characteristics by increasing the gain of a current controller when a converter is switched in a speed controlling circuit having both positive and negative direction converters. CONSTITUTION:A current controlling loop having a sequential current controller 9 and a voltage controlling loop having a voltage controller 13 are provided within the speed controlling loop of the speed controlling circuit of a DC motor 2 having a positive side converter 3 and a negative side converter 4 connected in antiparallel to one another, and the gate pulse generator 17 of the converter and a normal and reverse switching logic circuit 18 are controlled by the output of the controller 13. A zero current detector 25 is provided in the current controlling loop, the zero time point of a main circuit current is detected when the positive and negative converters are switched, while the gain of the current controller 9 is increased in accordance with the detection signal, and the wasteful switching time can be shortened.
