sine pwm based 3 phase Inverter | SPWM | MATLAB Simulation

Sine PWM technique is very popular PWM technique and also easy to implement than any other PWM technique.IN this video i design a complete 3 phase inverter by using sine PWM

Thank you... How can we generate 3Phase SPWM waveforms using arduino or microcontroller

[@schoolboy8288]

So good i use the same logic with SVPWM thanks a lot😘

[@sivadharshinia5384]

heyy hii.. for the SVPWM, how do you fix the carrier wave frequency?

[@NadiaTorabi-pj3mw]

Hello, I connected your inverter to a boost converter whose voltage source is a fuel cell, but instead of 400 volts and 4 amps output current, it gives 0 and 0.5 amps and 250 volts, of course, I put it in the pi controller circuit. Tell me now. What should I do? Give me the correct current and voltage? I even put the resistance and ideal switch and step function, it still gives the same values..

[@RanitSengupta]

You have to put the perfect tuned controller values and also please run the circuit using normal dc-dc boost instead of fuel cell

[@NadiaTorabi-pj3mw]

@@RanitSengupta I first got the answer for the simple circuit without fuel cell, but it doesn't work with fuel cell.. I changed the controller value, can you send me an email to help?

Nice bro..

Nice work

[@wickbron8964]

Hi sir, in your sine wave block for the phase(rad) section value you’ve input -2*pi/3 can I ask why? Isn’t it suppose to be 4*pi/3 cuz it 0(degrees), 120(degrees), and 240(degrees) which is 4*pi/3?

[@RanitSengupta]

Yes yes you can give 4*pi/3 also.ultimately both are equal.0 120 240 or you can say 0 120 -120 both are same.

[@RanitSengupta]

Before giving the values in the block you can read the block specification which is shown on the top of the block.

Hello bro If there is fault in inverter then how it can tolerate means motor still able to run after one leg faults of inverter. Can you help me in this.. how can made my simulink model . If you have idea then please help.

What is the need for changing variable step to fixed step??

[@priyadarshan229]

Nice bro. I need a small help. What to do for 120 degree conduction mode?

[@RanitSengupta]

In case of 120 and 180 conduction mode just use simple pulse generator and according to theory give the pulses and delay

[@priyadarshan229]

@@RanitSengupta the one you have shown itself works in 180 degree conduction mode right?

[@RanitSengupta]

No they are different.because in 180 conduction mode the switches will conduct for 180 degree, neither less nor more than that in a total cycle of 360.In sine pwm the pulse width generate depending upon the reference sine wave.and you can check that the conduction time for the switches are not 180.they will vary

[@priyadarshan229]

Okay. Thank you bro

Heyyy please help me with this. how to know know the modulation index for the pwm u designed. and how can we change values??

[@RanitSengupta]

Amplitude Modulation index=reference gain/carrier gain. Just decrease or increase the gain value of reference wave(Sine wave) you can observe the change

[@salminandalib3939]

Hi where can I give the switching frequency? I am not clear

[@RanitSengupta]

The carrier signal or triangular singal frequency is the switching frequency

@@RanitSengupta thanks. Can u pls tell me how to do this with trapezoidal PWM ?

@@salminandalib3939 same as this technique.just you have to generate 3 phase trapezoid carrier reference instead of sine wave

[@salminandalib3939]

@@RanitSengupta sir, I am suffering to generate three-phase trapezoidal waveforms that I can compare with the carrier signal. I don't know how to tune the parameters for the "repeating sequence" components to make them 3 phases?

Sir when I modelled this with wecs based on pmsg then I did not get the desired output

You need to check the inverter rating with respect to pmsg yuo have used

Hey, thank you for this good video. How can I realise a switching time of 17 kHz?

[@RanitSengupta]

Means you want to give 17 khz switching frequency?

[@davidrunde93]

@@RanitSengupta Yes, my goal is to achieve a switching time of 17 kHz. In 6:47 yout carrier frequency is 2 khZ. As a result of that the switching frequency is 1 kHz. Am I right? Do I have to replace the 6000 in 6:47 with 51000? But if i do this my simulation doesn´t worked. Should I also replace the step size? Thank you so much for your help! :)

[@RanitSengupta]

@UCmxEIbEacYMk2cE6QQ_7Vdg In the PDpwm technique triangular wave is the carrier signal.so Here I give 2khz as a carrier frequency or you can switching frequency.In the block it is given as time. We know f=1/t.
