Analog SPWM Card for Sine Wave inverters || Generate SPWM control signals for H-Bridge

Hello everyone!
Thank you for tuning to my channel. This video is about creating and demonstrating the concept of SPWM signal generation which can be used to make pure sine wave inverters!
This entire project is made out of discrete analog components and there is no use of any microcontroller or ASIC. It's a completely analog circuit but generates perfectly stable 50Hz signal.
There are a total of 4 outputs from this card which can be used to drive H-bridge and create an AC waveform at the output of an inverter.
Please share your feedbacks and suggestions in the comments below.
Support my channel and let me know if you want me to make a detailed video on the working theory behind this card.

[@ArshadMehmood-kz6ez]

Very nice
Thanks

[@harikamalakarreddydarapu7410]

This is really great design and nice explanation too

[@UtsavShah_25]

Glad you like it!

[@Dc_tech386]

Your a really good engineer

[@anuwattanaiatkhlik1306]

Good, Thank you.

[@kdcreativity6201]

Impressive 👍🏻😻🎃

[@UtsavShah_25]

Thanks!

[@amirmahdisalari3528]

Good

[@jboy4real]

Please how did you get 50Hz at the out put of your spwm design

[@coucouj2781]

Why not using 2 complementary triagle wave as carrier compatef to a sign wave (wein bridge) reference signal.

[@komalthakkar3681]

👍🙂

[@UtsavShah_25]

Thank you!

[@jomoncj9785]

After long waiting... Congratulations..is it need
MOSFETs driver ics???

[@UtsavShah_25]

Thanks! This will require additional MOSFET driver ICs

[@user-rv2bw8by9w]

I repair microtek luminous eapro genus sinewave inverter but i appreciate your design

[@UtsavShah_25]

Thanks a lot!

[@user-rv2bw8by9w]

@@UtsavShah_25 Because i repair analog circuit analog (3524 driver and lm324 comparator based long card and 121 inverter kit) circuitis too fast and much better than today microcontroller based square wave or sine wave inverter because digital ic cannot go into protection fast like analog circuit

[@wechselrichterschaltungen]

Good morning,
would you please also publish the circuit diagram for this interesting sine wave inverter?
regards...

[@wechselrichterschaltungen]

Hallo, eine tolle Schaltung ohne Mikrokontroller und mit Bauteilen die weit verbreitet sind! würden sie auch das
Schaltbild veröffentlichen? viele grüße aus Deutschland......

[@smartups1]

Please make next video .

[@andrewlamidi8317]

Hi, Utsav Shah l ofI, am Ganiyu Andrew Lamidi, from Nigeria, I, like like your lectures, they are comprehensive, especially with analog circuits. Please Sir, I will need you to make another video of the analog SPWM with circuit diagram schematic. And that will be more comprehensive to me please. I, am looking forward to getting a favorable response from you sir. Thank you.

[@UtsavShah_25]

Thanks for writing! Glad to see my video was helpful. I will create a better circuit and share the schematic in a future project

[@imranarshad4737]

Hi.
Can you please share the copy of the pcb design you have made...

[@UtsavShah_25]

Working on an improved version, will share the details

[@jboy4real]

How do you get 50hz out put signal

[@UtsavShah_25]

It is by dividing the high frequency square wave signal coming from the crystal

[@jomoncj9785]

Hai....bro....are you still trying to develop improved version.... since 2 years...😀😀😀😀😀

[@jomoncj9785]

Whole circuit diagram please???

[@sagorrana2051]

Dear why u are irregular?

[@Electrondemon]

And this is not pure sine wave output

[@necipucuk6710]

Makalede anlattıklarını zaten bizde biliyoruz madem yaptın çalıştırdın şematik ve pcb verde çapını görelim. Sır değil artık bu projeler ortalığa saçılmış zaten.

[@Electrondemon]

Your circuit have many problem

[@UtsavShah_25]

There's always room for improvement
