Performance Analysis of DTC Methods of Two-Phase Induction Motors with Different Inverter Topologies

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. Essentialequations for controlling both torque and flux are presented and switching tables are derived. Different inverter topologies arecompared 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.
