This paper describes the design, analysis and experimental studies of a variable speed d.c. drive fed from a single phase dual converter, the d.c. motor field is separately excited. The dual converter is operating in circulating current mode. It incorporates cosine firing technique using integrated circuitry. A speed loop with PI controller maintains the desired speed irrespective of the load variation on the motor. An inner current control loop again incorporating a PI controller, protects the thyristors from overcurrents and also provides fast response overcoming the effect: of disturbances. The method effectively replaces the Ward Leonard system. The parameters of the PI controllers are designed on the basis of system relative stability and response of the drive system D-decomposition technique is used for finding the region of parameters for stable drive system and this is checked using frequency scanning technique. Experimental results are also given. |
