| Abstract |
This paper investigates the idea of supplying the switched reluctance motor with bipolar currents, obtained directly from an a.c. source (mains) which would eliminate the need for an input rectifier and a d.c. link capacitor in the electronic converter of the drive. The idea is based on the fact that the direction of the electromagnetic torque produced by a switched reluctance motor, is not dependant on the direction of the currents flowing through the motor windings. The power electronic circuit studied is suitable for use with a bifilar wound motor. It requires two switching elements and two diodes per phase. The control by position-dependant switching in the single pulse operating mode and the control by current limit In the chopping mode are investigated. It is shown that apart from having a undesirable harmonic content in the supply current the drive could be successfully controlled at lower speeds. |
