      The common strategy of speed control of single-phase induction motors depends mainly upon controlling the applied voltage on the motor. Changing the applied voltage on the motor can be effected by several techniques. Some on these techniques employ auto-transformers or add extra winding, as required, to the main or auxiliary winding. The other approaches use power electronic devise such as TRIAC. Each one of these methods have advantage and disadvantage.
      Single-phase induction motors are always small and are seldom built in sizes over fractional horsepower ratings. Existing frequency control devices offer a wide range of speed control but are considered expensive with respect to these small motors.
      A new concept would be to control the input supply frequency to a single-phase induction motor by a single controlled forced commutated device. This approach is the intent of this paper.
      The paper presents a new drive for single-phase induction motor. This drive employs a bridge rectifier connected with the stator in a non-conventional fashion. The speed of the single-phase induction motor is controlled by controlling the chopping frequency of the chopper switch. The attractive feature of the drive is that it effects both frequency and dc chopping simultaneously. The drive performance has received both theoretical and experimental investigation.
