Simulation of 12 Pulse Controlled Rectifier in MATLAB | SIMULINK
This video demonstrates the design and simulation of 12 Pulse Controlled Rectifier in MATLAB using MATLAB/SIMULINK. It consists of 12 thyristors connected to a three-phase AC supply displaced by an angle of 120 degrees apart. Two universal bridges are used for the simulation to reduce the complexity of the circuit. The firing angle considered in this design is 60 degrees. However, care has to be taken while entering them in MATLAB. Thyristors conduct when the amplitude of the supply is higher in comparison with the other thyristors. This circuit requires 12 thyristors for three-phase AC to DC conversion. It is also called a 12 pulse converter. It improves the ripple content in the output in comparison with 3 phase Full-wave controlled rectifier.
