An LSI firing circuit, in conjunction with a high-speed digital signal processor (DSP), has been developed to adjust the thyristor firing angle between 0 and 180 degrees for both positive and negative current control in a dual antiparallel-connected three phase power converter connected to a DC motor. A fast-response current controller is obtained by using feedforward techniques and a variable-str...
The design of reversing armature power supplies for DC motors is considered. An LSI firing circuit, in conjunction with a high-speed digital signal processor (DSP), has been developed to adjust the firing angle between 0 degrees and 180 degrees for both positive and negative current control in a dual antiparallel-connected three-phase converter connected to a DC motor.
