MATLAB SIMULATIV STUDY OF SEPIC CONVERTER
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 8
Abstract
A high-power-factor rectifier suitable for universal line base on a modified version of the single-ended primary inductance converter (SEPIC) is presented in this. paper. The voltage multiplier.technique is applied to the classical SEPIC.circuit, obtaining new.operation characteristics as low-switch-voltage operation and high static gain at low.line voltage. The new configuration.also allows the reduction of the losses associated to the diode reverse.recovery current and soft commutation is obtained with a simple regenerative.snubber circuit. single-ended.primary inductance.converter (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 arrangement has close loop system. The computer program used for simulation of SEPIC is MATLAB SIMULINK & . This project consists of design, simulating the model and stability and other analysis of proposed model.
