摘要：
Several techniques are available for the design of reversing armature power supplies for dc motors. An LSI firing circuit, in conjuction with a high-speed digital signal processor (DSP) has been developed to adjust the firing angle between 0 and 180-degrees for both positive and negative current control in a dual antiparallel-connected three-phase converter connected to a dc motor. A fast-response current controller is obtained by employing feedforward techniques and a variable-structure PI compensator to produce an optimal current response under both continuous and discontinuous current conduction.
