In this block select the power system block as shown in the figure below, Open the library browser and go to the simscape section in library browser as shown in the figure below, Open MATLAB and then open simulink and create a blank model as we have been doing previously and save it for future use. Lets’ now commence our discussion of implementing the three phase inverter on MATLAB’s simulink. A three phase AC voltage is shown in the figure below,įigure 2: Three phase AC Simulation of Three phase Rectifier in Simulink MATLAB The output of three phase rectifiers is a low pulsating DC. Those rectifiers the input of which is a three phase AC voltage are known as three phase rectifiers. A waveform of single phase AC voltage is shown in figure belowįigure 1: Single phase AC Three phase rectifier The output of such a circuit will be high pulsating DC voltage. Rectifiers whose input voltages are single phase AC voltage are known as single phase rectifiers. We have already discussed the former two types of rectifiers in previous tutorial, now we will discuss the later two types. Now lets talk about different types of rectifiers. Hence a three phase rectifier is now a days used in almost every house and is a very common device to be used. In every house the power supply provided by the government is three phase Alternating (AC) but most of our devices like laptops and mobile phones uses Direct voltage (DC voltage) for their charging. In electrical/electronics engineering, the word rectifier is recognized as a device which can convert an input AC voltage to DC voltage.
