Abstract
In this paper it has been investigated if there is a possibility to reduce the switching frequency for a two-level inverter by improving the direct torque control (DTC) algorithm by adding a non-switching condition when a new sector is entered. It is believed that the DTC switching table can be improved by adding a non-switching condition when sector change occurs. This will reduce the number of switching actions by up to 12 per electrical rotation without interfering with the electrical machine performance.
