I made an application with a sine table with values from 0-255 (8 bits) to generate the wave for PWM, with 120° of phase shift, using only Mosfets (IRFZ44N and IRF9540), including optocoupler with BC337/BC327 for swtiching before the Mosfets. I could make a "smooth" signal as well without burning anything. The PWM frequency was 10kHz. Would that be considered as a SPWM? I would like to try it with IGBT one day to compare.
I was hoping you would explain dead time to prevent short circuit on the H-bridge. Also some form of voltage feedback for voltage sag or input voltage fluctuation compensation.
Yes, "dead time" is a brief delay applied in switching circuits, such as H-bridges, to prevent short circuit conditions. For an H-bridge with IGBTs, a dead time of around 1-5% of the total switching period is common. This ensures safety and efficiency in typical IGBT-based H-bridge circuits.
Sir, very nicely , easy to understand the programming of a PWM microcontroller and how to generate sine wave voltage output using IGBT transistors from DC input. Sir, could you forward a circuit diagram to generate 3 phase voltage output with DC input. With Sincere Appreciations Vijay Mohan
Thank you. The 100% low-side method and the 50% offset method are two common techniques used for generating sinusoidal waveforms in sinusoidal inverters (often for applications like motor drives or uninterruptible power supplies). Both methods are used in pulse-width modulation (PWM) control schemes for producing AC outputs from a DC input, but they differ in how they generate the sinusoidal waveform, particularly in terms of how the modulating signal interacts with the switching signals of the inverter. Will try to do a video on this when time permits.
If the LED on your EGS002 board is blinking, it typically indicates a fault or warning condition that the board is detecting. Please go through the manual for fault detecting or get the help of a good technician.
Visit Google Scholar and search for terms like “DC to AC sine wave inverter,” “pure sine wave inverter design,” or “DC to AC power conversion.” You can refine your search to specific time frames or by sorting for recent papers to get the latest research.

Very nicely, easy to understand , explained.
Thank you
Thank you
I confused SPWM to Sine Wave working procedure before watching this video now I understand Thank You So Much
Thank you
best videos for explaining the core concept of inverter, thank you so much 🙏🙏
Thank you
Can't thank you enough.. you made the concept so clear and easy..Kudos for your efforts
Thank you
Excellent work dear..appreciate 👏 ❤
Thank you
Absolutely brilliant!
Thank you
thanks for provide description . 🙏
Thank you
Finally I understood pwm now.Thanks sir🫂
Thank you
great explanation
Thank you
fantastic work, thanks a lot

Very valuable explanation delivered in poor AI fashion. Thanks anyways

hi how i can contact with you
Than you.
Sorry, I don't have PDF drawings on these.
Was the voice PWM generated as well?
Concentrate on the content
:D
Hi please make a video on details on the value to be uploaded in a programme as sine wave lookup value
I will try to do a video on this, when time permits.
Sir,
Is it possible to share the circuit diagram of the controller , to develop one for my vehicle
Thank you
Sorry, I don't have PDF drawings on these.
Good video. Do you have anything that talks about the 100% low-side method and 50% offset method for Sin Inverters?

Tuyệt vời

Any reasons why my egs002 led blinks??
If the LED on your EGS002 board is blinking, it typically indicates a fault or warning condition that the board is detecting.
Please go through the manual for fault detecting or get the help of a good technician.
Is there any research papers on this. How can i reference this?
Visit Google Scholar and search for terms like “DC to AC sine wave inverter,” “pure sine wave inverter design,” or “DC to AC power conversion.”
You can refine your search to specific time frames or by sorting for recent papers to get the latest research.
ขอโค้ดได้มั้ยค่ะ🙏
hi how i can contact with you
Thank you.
Sorry, I don't have the codes with me.
What a terrible fake voice. Please don't use this again. Not only does it sound terrible, the text is also hard to understand.
Can't thank you enough.. you made the concept so clear and easy..Kudos for your efforts
Thank you
