Delta connection of three phase thyristor placed at the open star point of the rotor circuit was investigated. The various functional blocks of the system which govern the behaviour for a variation in operating point were derived. The responses for load and reference speed perturbations were obtained practically and analytically. The result is 20% improvement over the conventional speed control.
