Abstract :
A novel scheme is formulated to control the dc link current of a current source inverter induction motor (CSIM) drive which greatly enhances the current response with substantial benefits on the overall dynamic performance of the drive. In addition to conventional closed-loop control with a PI regulator, the novel scheme incorporates a function generator to compensate for the motor back-EMF seen by the dc link. Application of this scheme to an indirect field-oriented CSIM drive is presented, and improvement in the drive performance is documented.
