“…In recent years, the microprocessor technique has been applied to control the speed of ac and dc drives for obtaining high performance of the drive due to their fast, accurate, versatile, and diagnostic characteristics instead of traditional control scheme [5]. The applications of the microprocessor for the speed control of the drives are shown in papers [6][7][8][9][10]. The drive under investigation shown in fig.1 consists of a slip ring 3-phase induction motor, a 3-phase uncontrolled converter, a smoothing inductor, a 3-phase controlled converter and a 3-phase step up transformer.…”

Microprocessor based firing control scheme of static slip energy recovery (SER) controlled slip ring induction motor drive is described. In the scheme the microprocessor generates firing pulses and also decides the pair of thyristors of the controlled converter to be gated. It uses less number of hardware components. The oscillograms at different points of the firing circuit and at the output of the controlled converter are presented. These oscillograms resemble with the theoretical wave forms.

“…By using a divide-by-six counter to select the firing sequence, it was able to reduce the number of components [4]. In recent years, the microprocessor technique has been applied to general dc motor control systems for higher performance [5], [6]. The interface circuits between microprocessor controller and original firing circuit tend to increase the overall cost and decrease the advantage of microprocessor.…”

A firing scheme based on a microprocessor to control an antiparallel-connected three-phase thyristor dual converter is presented. Using table-look-up algorithm to speed up the response, it gives a full range control of the firing angle between 0°and 180°for both positive and negative current control. The maximum time delay required to correct the firing angle is one-sixth period of the ac power source. The firing angle between 120°and 180°is used for the regeneration braking to achieve the required dynamic performance in four quadrants. Built with all digital circuits with no further adjustment, this system is more reliable and has lower cost.
