Abstract :
This paper describe the step down three phase ac/dc converter involving a simple topology of 6 ideal switches using MATLAB/SIMULINK simulation model. This project consists of two parts. First part is ac-to-dc converter and the second parts are consisting of buck converter. In this project use the fast control strategy of three phases ac/dc by pulse-width modulation (PWM) converter and the input current is regulated to be sinusoidal and the source power factor can be controlled at unity. This project considered the total harmonic distortion (THD) which was defined as the power summation ratio of all harmonic components to the fundamental frequency power. The result of MATLAB/SIMULINK was analysed at the end of this paper/project.
