A high - power - factor rectifier suitable for universal line base on a modif ied version of the single - ended primary inductance converter (SEPIC) is presented in this. paper. The vol tage multiplier.technique is applied to the classical SEPIC.cir cuit, obtaining new.operation characteristics as low - sw itch - voltage operation and high s tatic gain at low.line voltage. The new configuration.also allows the reduction of the losses ass ociated to the diode reverse.recovery cu rrent and soft commutation is obtained with a simple regene rative.snubber circuit. single - ended.primary inductance.conv erter (SEPIC) step up the input voltage 220 Vdc to 1200 Vdc with the switching frequency of 24 kHz. For close loop operation of single - ended primary inductance converter (SEPIC) with PI controller that uses to control the behaviors of the system in linear .This arrange ment has close loop system. The computer program used for simulation of SEPIC i s MATLAB SIMULINK & . T his project consists of design, simulating the model and stability and other analysis of proposed model.
