ABSTRACT
ABSTRACT: Power Quality Improvement is a major focus in recent electricity quality improvement technologies. Power factor correction is applied to the circuits that include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. The proposed BLCSC converter is operating in a discontinuous inductor current mode; The Brushless DC Motor speed is controlled by varying the dc bus voltage of the voltage source inverter (VSI). Via a PF converter. Therefore, the BLDC motor is electronically commutated such that the VSI operates in fundamental frequency switching for reduced switching losses. Moreover, the bridgeless configuration of the CSC converter offers low conduction losses due to partial elimination of diode bridge rectifier at the front end. The proposed method is simulated in MAT Lab tool and achieved the expected results.
