Research whose aim is to develop an educational package for variable speed drives is described. The program is PC-based, and is intended to assist students in learning how variable speed drive circuits work. Simulation studies are performed on selected preconstructed circuits, and vital information like speed, torque, and voltage can be obtained. This program is based on an existing package called CASED, developed for the dynamic and steady state simulation of electrical drives. The preconstructed circuits include a number of converter topologies, including single-phase, three-phase half-wave, and six-pulse converter circuits. All the above are AC to DC convertors. The package also includes single- and three-phase inverters and special application circuits like 12-pulse converters
