Design and Simulation of Three Phase Controlled Rectifier Using IGBT

Abstract An electric power can be converted from one form to another form by using power electronics devices. The function of power electronics circuits by using semiconductor devices as switch is modifying or controlling a voltage. The goal of power electronics circuits are to convert electrical energy from one form to another, from source to load with highest efficiency, high availability and high reliability with the lowest cost, smallest size and weight. The term rectification refers to the power circuit whose function is to alter the ac characteristic of the line electric power to produce a “rectified” ac power at the load side that contains the dc value. Rectifiers are used to convert the AC voltage into DC or low-frequency AC to supply the different combinations of the load like the resistance and the Inductance. In this project task, the rectifier circuit should be possible to produce a variable average voltage by controlling the delay of 60°. A versatile method of controlling the output of a full-wave rectifier is to substitute controlled switches such as IGBTs for the diodes. This paper introduces the characteristics of the threephase full-controlled bridge rectifier circuit, and MATLAB / Simulink module for the full control of three-phase bridge rectifier circuit is narrated briefly, the model for the three-phase bridge full-controlled rectifier circuits has been made, MATLAB software were used for different firing angle, a different trigger pulse when the circuit was simulated the output waveform when the firing angle change, or 6 pulses synchronized trigger pulse width is changed. The output is controlled by adjusting the delay angle of each IGBT, resulting in an output voltage or output current which is variable over a limited range with programmed the Arduino UNO R3.
