Abstract :
In this paper, direct torque control of symmetrical two-phase induction motors using two- and three-leg inverters is analyzed and utilizing four-leg inverter is proposed. Essential equations for controlling both torque and flux are presented and switching tables are derived. Different inverter topologies are compared from the view point of switching frequency and the operation of control system in high speed applications. Performed analysis and calculations are validated by dynamic simulation.
