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

Nowadays switched reluctance motor (SRM) drives are widely used in the field of controlled electric motor drives. This 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 is not significantly higher at a Miller-kind (n+1) transistor converter controlled n-phase drive - in other words a reduced switching item number converter feed SRM - than at independent current control in each phases carried out with 2n transistors
