Hi! I plan to follow all your videos from beginning. Your videos are excellent! Could you kindly share the ripple current file to me? I really appreciate it.
email: weiran4@ualberta.ca
we already did that bro.
Thanks a lot *Tech Simulator* for adding video on Inverter in systematic way on UA-cam. Your video is so much useful.
Thanks
NOTE: the capacitance and inductance values are in F and H units while u need to put 6.23*10^-6 for capacitance and 4.06*10^-3 for inductance
Thanks a lot
One thing not clear is D(wt) = Ma*sin(wt). How could D be negative. Shouldn't it be D(wt) = (1+Ma*sin(wt))/2 ?
Also, the LC filter values were chosen w/o taking the load value (R) into account. In the simulation you chose 100 Ohms. What if the load changes? How would you control the damping ration of the LPF? On command or load change you may get oscillations and instability.
Hello, thanks for your video, in which book or document can I find the formulas you use?
Hello! Thanks for the video, it was very informative! At 2:55, I did not understand the factors 8.69 and 1.414 that do not match with any value in the formula in the middle row. Request you to explain it in some detail please!
8.69 is 2000/230. That is output power/ output voltage. 1.414 is root(2) to find the peak value
Thanks sir... I really appreciate it, because i was also confused about that factors.
@@TechSimulator Thank You Sir i am also confused here
would you mind to explain why did you chose P= 2000 ?
thanks in advance@@TechSimulator
@@djelloulkarib7313 because he is designing a 2kW inverter.
I have liked a lot with your classes. Congrats
Thank you
Dear Sir I have a question.
during simulation, If I use capacitor instead of battery and I selected initial voltage as 5V. so, How i can choose the main value of capacitor as capacitance?
i m getting current value as 15Amp maximum. for 2kw op power and 230V op voltage we need to keep 26.45ohms na sir
Hello sir.. @0.56 sec of this video.. u have told the inductor ripple current to be 20% . How did you calculated that ripple value.. Please provide the formula for that
very very good explanation thanks a lot.
can you do for the full bridge dc dc converter with close loop.
Sir I have a doubt. In the inductor design formula when substituting the values in the denominator I saw 8.69. What is that constant. Can you kindly explain.
its simple
first calculate the current for given load,
i= Power (2kw given)/ V(230v) = 8.69A
next he has multiplied by 1.414 which is nothing but root(2) to get peak current
and finally he has taken ripple percentage as 20% hence multiplying by 0.2
@@aquilrodrigues8155 I followed a similar method for a 500W inverter
But the values substituted gives me only 40W at 230V. Any further increase in load power reduces the voltage down. The amount of capacitor current used in the filter increases. Can you help me?
Hi, thank you for this video, but in my case I am modeling on PSCAD with same specification you mentioned but I got sin wave at the with C = 250uF, any suggestion how to design filter in efficient way I did on hit and trial way.
Thanks
Thank you sir for this video.
Best UA-cam matlab channel.
Sir can you give detail video on dc to 3 phase ac sine wave detail vedio with matlab simulation?
already there in my channel
Brother i am trying the same specification circuit in matlab but it does not gives me a pure sinusoidal wave form it gives me voltage in negative values at the output
hi do u have an example on series resonant parallel load inverter with pulse generator as switching igbt in matlab?? thankyou so much for this clear and great video!!
hello sir. how can i add one more inverter in that simulation? is there anything will change if that simulation? or maybe just add inverter normal tu without add another component?
Great work. How to know what should be the DC input voltage (Vin) for a particular output voltage of an inverter (single as well as three-phase). Like any justification for choosing 400 V input for 230 V output?
Please watc this video. i have already explained it here. ua-cam.com/video/GGN_JSXi4Z4/v-deo.html
Thank you for the video! just a side note, 400Vpeak/sqrt2 is 282.84Vrms , you r thinking voltage line that is divided by sqrt3
RMS voltage for a DC source is 400V
sir, how you can get amplitude 0.45 in sine wave?
Same .. please explain
0.45 is the required modulation index when the input voltage is 400 and required output voltage is 230V RMS
@@TechSimulator Sir how do you calculate this modulation 0.45 did you use this formula Vac=m×(Vdc/(2*root(2))) or other
hello sir,Nice tutorial. I am trying to change the filter values according to my requirements. I am getting the wrong values after simulations. can you send me documentation on the filter? how do set the exact values?
Is it also an example of pure sine wave inverter ?
Thank you, sir. got it very helpful. can you please provide any book/paper for reference?
Is that diode across each of those bjt transistor?
Sir how to calculate power in this case I am not getting the same 2kw as you said
Same problem bro, any idea how to get 2kw?
How to reach you for getting simulation s

Excellent video sir. Thank u very much.
Thank you
I tried with 48V Dc voltage and to get 230V at the output side. Did the calculations following the formulas. But failed to get 230V. Getting output of whatever the voltage I am giving at the DC voltage
Sir Can plzz you make viedo of How SSSC inject voltage in quadrature with line current in sending end receving end
how do you calculate delta Ipp-max ? what is actual formula for it?
Sir how to calculate switching frequency of PWM
In the numerial value of inductor in the denomenator you have taken (8.69*1.414) as a term which cannot be related to about formula components. Please refer time: 2.55min. Can you please clarify?
i am considering a 2Kva inverter. So for a single phase 230V RMS voltage, the maximum current would be 2000/230 = 8.69. this is value is in rms. so we need to take peak value of it. so we multiply this value with root 2, that is 1.414.
@@TechSimulator can we implement the same for a 60kW Inverter?
Single phase or 3 phase?
For this huge power, people usually dont use single phase inverter.
@@TechSimulator actually I need to implement Dual Active Bridge in order to attain DC-DC conversion from one DC level to another DC voltage, with control over both voltage and current control. Can you recommend some video or tutorial to refer for the same.
Hi, can you please help finding the transfer function of this model? or explain how we can get it.
Sir, will this method work on single-phase multilevel inverters? Less say 5 levels.
The design equations will be different
Excuse me, sir. I have a questionl. How did you get that 2 KW power output? Thank you.
I wantated demonstrate a 2 kw inverter, so i choose that value. You can choose whatever value you want
@@TechSimulator thank you sir
Sir, im unable to get the output as 2kw, I have used the same values but still not getting the @kw output. Any idea why that is the case?
@@TechSimulator
Thanks very very exellent
Thank you
Dude, I love you!
Good example. But I am not getting the required current output. I need to convert 12 V from battery to 12V sine wave at 500W. Can u help
Share the model

Welcome bro, but a lot of work still need in this field
I am trying to make different videos
Nice video
Can we make a open loop for statcom to reactive power compensation in grid
I dont think we can make an open loop statcom
@@TechSimulator thank you
Yes bro it is quite useful
thank you
one of the slowest and techniques I have ever seen
Can you give a detail how you calculate the ripple curent
Its very difficult to explain it here. If you could share your email, i can make a document with detailed explanation of ripple current calculation and send it to you.
@@TechSimulator thank's ; email : hamza.er.pv@gmail.com
@@TechSimulator pl share it also santu300493@gmail.com
Sure. I will share it.
can you share to me @ sahilgauravbce@gmail.com
When I simulate the following warning appears
[Warning: You have required continuous-time simulation of a system containing switches or nonlinear elements.
The ode23tb variable-step stiff solver with relative tolerance set to 1e-4 generally gives best accuracy and simulation

Hello Sir, in 2:55 i didnt understand what 0.2 is?
Current ripple 20%
How to calculate delta ippmax
What is Fsw stand for?
switching frequency
(d(∆_ilpp))/dt=0 give us K*cos(wt) (1-2*ma*sin(wt) ) = 0 where K=(r*E)/(L*Fsw) and the solution of this equation gives us two solutions sin(wt)=1/2*ma et k*cos(wt)=0 then wt=sin^-1(1/2*ma) et wt =pi/2 , how you fund only sin(wt)=1/2*ma ?
This video is misleading. The suggested filter does not give sine output as it dose not filter 50 Hz square wave which is necessary for getting bipolar output. Some one can try with design value of L and C and see the result.
pls contact me at my email i can give you the working simulatio file
how we got 8.69 in Li expression?
2000/230
Sir, How to select the Dc link capacitor
You can select value of capacitance based on the max permissible voltage ripple. You also need to consider the ripple current of capacitor, that you will get from the datasheet. If the ripple current is less, then you need to connect multiple capacitors in parallel
