AC chopper voltage controller-fed single-phase induction motor employing symmetrical PWM control technique

Abstract Due to the growing demand in improving the performance of motor drives, there is an increasing need to improve the quality and reliability of the drive circuit. AC-to-AC converter schemes using pulse width modulation (PWM) are proved to achieve substantial advantages over conventional line-commutated AC controllers. With the increasing availability and power capability of MOSFET's and IGBT's switches, PWM converters can efficiently and economically be used in low and medium power applications. However, such controllers have been applied only to control the voltage of passive R-L loads. In this paper, the performance characteristics of a symmetrical PWM AC chopper controller-fed single-phase induction motor drive are evaluated. The developed analysis is experimentally verified by an experimental verified mathematical model is used for this purpose.
