Optimal Control of Transistor SRM Converters with Reduced Number of Switching Element

Nowadays switched reluctance motor (SRM) drives have been widely used in the field of controlled electric motor drives. The paper proposes a simple control method for SRM drives. Current control of the reduced switching item number SRM drives contain modified current reference signal. This method provides that torque ripple would not be significantly higher at a Miller-kind (n+1) transistor converter controlled n-phase drive - in other words a reduced switching item number SRM converter feed - than at independent current control in each phases carried out with 2n transistors
