Abstract: This paper presents power factor correction (PFC) of single-phase induction motor (SPIM) using reconversion dual input single-ended primary inductor converter (DIPSEPIC) with Fuzzy indirect field-oriented control of speed. This work deals with an alternative approach to improving the power factor and the efficiency of a single-phase induction motor utilizing induced electromotive force (EMF) in the open auxiliary winding, which is unutilized during running conditions in a conventional SPIM. The auxiliary winding power can be varied in order to achieve control over the phase angle and current. A closed-loop control scheme with PFC reconversion DIPSEPIC is proposed. The design and development of the novel PFC reconversion DIPSEPIC converter is presented. The assorted parameters are executed, and the simulation responses of the model under diverse conditions are determined. The unified approach is virtually acquired using MATLAB Simulink model, and the same has been implemented in real-time by employing the TMS320F240 digital signal processor platform. The performance of the proposed drive is correlated with that of the simulation model. The implementation of the suggested framework has shown an improvement of the power factor and of the efficiency of the motor. Moreover, the speed control of single-phase induction motor using the Fuzzy indirect field-oriented control (IFOC) had increased stability to sudden speed changes and load torque distortions.
