AN INVESTIGATION ON SWITCHED RELUCTANCE MOTOR AND ITS POWER CONVERTOR CIRCUITS

This paper briefly describes the disadventages of existing power convertor circuits used with the switched reluctance motor. A range of power convertor circuit has been proposed that overcomes many of these disadvantages.The design concept and operation of the new power convertor are then introduced.The new power convertor scheme retains the advantages of the asytnLmetric half bridge,allowing the switches to be rated at a voltage close to the motor, but uses only one switChes per phase winding. Switches in the new power convertor are connected to two phase winding of the motor.Test results and praCtical implementation of the new power convertor circuit are given.These results show that more torque is obtained from a standard four-phase motor with the new power convertor, compard with any other power convertor with one switch of the same voltage rating per phase winding.
