The phase shift of the first pulse generator will be 0 degrees and 60 degrees of the second and so on. The last thing to place is the ground, from the same section as of load, select the block named ground and place it in the model as shown in the figure below,ДЄt the input side of the bridge we created previously, connect the DC voltage source and at the output connect the load (change the RLC load to only resistive load) with each branch to each row as shown in the figure below,ДЄrrange all the 6 pulse generator with each of the thyristor and connect them.

From the fundamental blocks section, select the block named elements and in this section select the series RLC branch and place it to the model as shown in the figure below,ДЄlso in order to observe the output we need to place oscilloscope, place 3 scope blocks from the library browser on the model as shown in the figure below, As we are working with 3-phase inverter so we need to place three such measuring devices.ДЄlso we have to place the load to observe the output of he inverter. Now for the output side select the measurement block in the fundamental blocks section and in this section select the block named voltage measurement as shown in the figure below. We need a different pulse generator for each of the thyristor hence place 6 different pulse generators for every thyristor. In the library browser search for the pulse generator in the search bar and add the pulse generator to the model as shown in the figure below, To provide pulses to the thyristor we also need to place pulse generators to the model. In this block select the DC source ( input of an inverter ) and add it to the model as shown in the figure below, Now in the fundamental blocks section go to the sources section as shown in the figure below, This block contains the definition of all the power blocks used in simulink and acts like a startup file for the model.

In the library browser, go back to the fundamental block section as we have used before, and select the block named power gui and add it to the model as shown in the figure below, Now double click on the thyristor block and in the block parameters dialog box, uncheck the point of showing measurable port as shown in the figure below, Connect all of them to make a bridge as shown in the figure below, Place 6 such diodes on the model we created previously and arrange them in three rows having 2 thyristors each. From here we will select the thyristor block named as IGBT / Diode as shown in the figure below, In an inverter as we know, thyristors are used in place of diodes (as in rectifiers). In this section go to the power electronics block, in this block all the elements related power electronics are provided as shown in the figure below, Now go to the fundamental block present in this section as shown below, In this section select the block named power system as shown below,ДЇrom this section, now select Specialized Technology block as shown in the figure below, In the library browser select the section named simscape as shown in the figure below, Now, click on the library browser icon on SimulinkвЂ™s recently created model. Create a new blank model and save it in the first hand so you can access it in future. Open MATLAB and then open Simulink using the simulink icon on MATLAB as we have been doing in previous tutorials. Design Three Phase Inverter using Simulink MATLAB

In the explanation below, we will design a three phase inverter in Simulink. In the circuit, a bridge like circuit comprised of IGBT transistor is used which converts DC to AC 3 phase inverterДЄlternatively, a three phase inverter uses two input DC sources, using 6 IGBT transistors to convert DC voltage into AC voltage and the output of such a circuit will be a three phase AC waveform with a phase difference of 120. Single phase inverter is the type of inverter in which only one DC source is used and the output thus formed is a single phase AC waveform. Inverters can be classified into two major types

However, DC can be defined as a constant source of voltage which remains either positive or negative through the course of time. For the beginners, the definition of AC voltage can be taken as the voltage which changes its direction from positive voltage to negative across same terminal in a specified period of time over and over again. The basic purpose of an inverter is to convert the Direct Current (DC) to alternating current (AC), which is no doubt the opposite of rectifiers. In electrical engineering inverters are one of the basic circuits used and are mostly used in UPS(Uninterrupted Power Supply) which is present in almost every house now a day.
