Research of PFC Circuit Based on IR1150

This paper studies the principle of power factor correction,and main circuit based on the chip of IR1150 is designed.Simultaneously,parameters of the main circuit are analyzed and calculated,and these parameters are proved to be effective and correct by experiments.Power factor of the system is greater than 0.99,and THD is less than 10 %.The system's performance is better and the output voltage is steady when input voltage varies from150V to 260V.
