Both these terms are necessary to explain AC signal. Frequency can be defined as the no of waves passing through a particular point in one second.

Period of an AC cycle can be defined as the time taken by the AC voltage to complete its one cycle.

РІР‚ВQРІР‚в„ў is the no of pulses per half period and when we will multiply it with 2, we get no of pulses in full period, which is РІР‚ВNРІР‚в„ў.

MATLAB command to calculate the period of an AC signal is given below:.

No in the next part of the tutorial, we are going to calculate the no of pulses per period of the sine wave or AC Signal under consideration.

Up till now we have entered the known values of the signal under examination.

Next 2 formulas the used to calculate Resistance(R) and Inductance(L) of the load respectively.

In MATHEMATICS pi has a constatnt value which is РІР‚В2.14РІР‚в„ў. while the other РІР‚ВpiРІР‚в„ў is a built-in MATLAB function.

РІР‚ВphiРІР‚в„ў is the load phase angle in degrees.

MATLAB Commands to calculate phase angle, Resistance and Inductance of the the load are given below:.

The parameters of the load signal which we have entered in the above commands (part 2).

Coming towards the Third part of the CODE, which is to calculate load parameters.

MATLAB code will ask these values from user to enter them manually according to the that signal, which is under consideration. of pulses per half period of the given cycle.

РІР‚ВphiРІР‚в„ў is the phase angle of load in degrees.

РІР‚ВmaРІР‚в„ў is the modulation index and its value varies from 0 to 1.

As you can see in the above code that Firstly it is asking frequency then comes the variable РІР‚ВZРІР‚в„ў, which is load impedence in per-unit and we have kept its value 1.

This command is used at that place if we need data from external source, which means if user will enter that data according to the input signal.

In the next steps, you can see that i have given the РІР‚ВinputРІР‚в„ў command.

As you know that the maximum value of Per Unit is one, so i have kept its value equals to 1.

The first command is РІР‚ВVrinРІР‚в„ў which is RMS value of the supply voltage in Per Unit.

Q=input(РІР‚ВThe number of pulses per half period = РІР‚В) Phi=input(РІР‚Вthe phase angle of the load in degrees = РІР‚В) Ma=input(РІР‚Вthe modulation index,ma, (0The code to do all this is given below:Р”Р‡=input(РІР‚ВThe frequency of the input supply voltage, f = РІР‚В). Since we are analyzing the PWM of AC signal and we need to enter the data of that particular signal, which we are going to analyze.

Now coming towards part 2, which is to enter some information from user side.

In dispaly command i have written the title of my project, which is РІР‚СљSinusoidal Pulse Width Modulation of AC SignalРІР‚Сњ.

Then the next command is РІР‚Вdisp(РІР‚В РІР‚В)РІР‚в„ў, and this command is used to display anything in command window.

РІР‚ВclcРІР‚в„ў and РІР‚Вclear allРІР‚в„ў command will clear the command window and remove all the variables already existing.

The commands are given below:Р”Вisp(РІР‚ВSinusoidal Pulse Width Modulation of AC SignalРІР‚в„ў) This is done through MATLAB language and we have commands to do this. Now first thing to do is to clear the command window and remove all the previous variables or functions from MATLAB.

Stay tuned and believe me you will learn something new from this project.Р”Р„nalysis of Sinusoidal Pulse Width Modulation of an AC SignalР”Р‡irst of all open your MATLAB software and a command window will appear. Now without wasting any time, I think we should move towards the CODE of the project. Since in this tutorial we are working with-in MATLAB premises so we will only discuss CODE and no hardware design involved in this tutorial. If you recall my previous project tutorials, in which I have generated PWM through 555 timer. For example in modern electronics projects PWM is generated through some type of micro controllers or 555 Timers. Square wave is in fact a signal which is generated through switching between ON & OFF states. We can say that some Digital Control or some Electronics algorithm is used to generate square waves. Pulse Width Modulation or PWM is a technique which is used for getting Analog Results with digital means. Before doing that first of all let me explain what is meant by Pulse Width Modulation. I will explain the code step by step and at every step we will see that what are the purpose of commands, which are written in that particular code. I will try to explain this tutorial in parts. Today I am going to share a very interesting tutorial which is Analysis of Sinusoidal Pulse Width Modulation of AC signal. Hello friends, hope you all are fine and enjoying.
