While the Direct Torque Control (DTC) method has been successfully applied to almost all conventional AC machines, it has not been considered so far as a potential mean for controlling doubly-excited systems. This paper attempts to fill in this gap, by exploring the principles and implementation aspects of Direct Torque Control (DTC) for the BDFRM. The presented results demonstrate good controller performance over the entire supply frequency range for the maximum torque per inverter ampere control strategy.

Three types of power devices are evaluated in the effort: high power bipolar or Darlington transistors, power MOSFETs, and asymmetric silicon control rectifiers (ASCR). The Bipolar transistors, including discrete device and Darlington devices, range from 100 A to 400 A and from 400 V to 900 V. These devices are currently used as key switching elements inverters for ac motor drive applications. Power MOSFETs ...
