How pure sine wave inverter works / How to program SPWM microcontroller / Pulse width modulation PWM

#SPWM (#sinusoidal_pulse_width_modulation) microcontrollers are used in #pure_sine_wave_inverters to generate more accurate AC sine wave.
This #microcontroller can store the required commands, to generate the necessary waveform for the #inverter, through proper design of switching pulses.
The basis is to use an #H_bridge with #IGBT_switches, to reverse the load current, by inverting the DC voltage across the load terminals, alternately.
All these things are explained well in this video, with fine animation work.

I confused SPWM to Sine Wave working procedure before watching this video now I understand Thank You So Much

[@ElectroAcademyEA]

Thank you

[@MangoBee093]

best videos for explaining the core concept of inverter, thank you so much 🙏🙏

[@ElectroAcademyEA]

Thank you

[@purohitamadithyaudaykiran4320]

Can't thank you enough.. you made the concept so clear and easy..Kudos for your efforts

[@ElectroAcademyEA]

Thank you

great explanation

[@ElectroAcademyEA]

Thank you

[@SyedYAli]

Excellent work dear..appreciate 👏 ❤

[@ElectroAcademyEA]

Thank you

[@juliacloete7564]

Absolutely brilliant!

[@ElectroAcademyEA]

Thank you

[@therealromster]

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.

[@JISHNU1901]

Hi please make a video on details on the value to be uploaded in a programme as sine wave lookup value

[@vijaymohan9354]

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

hi how i can contact with you

[@ElectroAcademyEA]

Than you.
Sorry, I don't have PDF drawings on these.

[@tahiriqbal7648]

excellent sir

[@ElectroAcademyEA]

Thank you

[@dereklaur2154]

Good video. Do you have anything that talks about the 100% low-side method and 50% offset method for Sin Inverters?

[@ElectroAcademyEA]

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.

very good

[@ElectroAcademyEA]

Thank you

[@lepton099]

fantastic work, thanks a lot

[@ElectroAcademyEA]

Thank you

[@vijaymohan9354]

Sir,
Is it possible to share the circuit diagram of the controller , to develop one for my vehicle
Thank you

[@ElectroAcademyEA]

Sorry, L don't have PDF drawings on these.

[@SrDelbioLima]

Was the voice PWM generated as well?

[@ElectroAcademyEA]

Concentrate on the content

[@tuanvu9478]

Tuyệt vời

[@ElectroAcademyEA]

Thank you

[@enochhamidu7861]

Any reasons why my egs002 led blinks??

[@ElectroAcademyEA]

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.

[@thomasmcgrath8876]

Is there any research papers on this. How can i reference this?

[@กิตติยาศรีบุรินทร์-ฉ4ร]

ขอโค้ดได้มั้ยค่ะ🙏

[@OSAMAHABDULLAH-pd4eq]

hi how i can contact with you

[@ElectroAcademyEA]

Thank you.
Sorry, I don't have the codes with me.
