This paper presents a novel approach in order to meet these objectives which are based on the reduction of the power conversion stages. Normally power factor correction circuit have reverse recovery current problem. In this paper describes eliminate
reverse recovery current by using Sic Schottky diode, and to provide the gate signal by ML4821 controller. Measurements of overall efficiency, switch and diode losses and conducted electromagnetic interference (EMI) are performed both with the SiC diode. And finally this paper got power factor will become near to unity. This scheme has the desirable features of high efficiency,
simple circuit and low cost compared to traditional switch mode power supply with power factor correction.
