In Power Electronics Application, the uncontrolled rectifiers are commonly used for AC-DC conversion which is located in the front end of industrial applications. The non-linear load naturally generates harmonic currents which cause major problem and affects the power quality at mains. Thus the high harmonic content of the power lines is resulting low power factor and voltage distortion. In addition several applications demand the capability of power regeneration to the power supply. These problems are alleviating by using Pulse Width Modulated (PWM) rectifiers which means the reduced THD can be achieved and power regeneration is possible. The converter switches are replaced by Insulated Gate Bipolar Transistor (IGBT) at its front end instead of diodes which is named as Active Front End (AFE) rectifier. The Active Front End converter is swelling solution for harmonic content elimination at the input line. This paper presents the field of Active Front End rectifier with reduced input current harmonics and it improves power factor, which increases the system stability and performance. The analysis and implementation of software is accomplished by MATLAB/SIMULINK and its hardware is developed in hardware as prototype model.
