In this video, we'll be discussing how to convert DC to AC. We'll be using a 3D animation to illustrate the concepts.
If you're ever in a situation where you need to convert DC to AC, then this video is for you! By the end of this video, you'll be able to understand how to rectify DC, and use this knowledge to solve practical problems. So make sure to watch it!
There are two forms of electricity - alternating current (AC) and direct current (DC).
DC is a linear type of electrical current - it moves in a straight line/flows in one direction. This current moves from the positive pole to the negative pole, while electrons produce electricity while moving from negative to positive.
For DC, the positive and negative poles always remain the same.
AC is a current that constantly changes its flow between positive and negative terminals. This means that electrons also change their flow, following the negative to positive end as the polarity changes.
The speed at which AC changes polarity and completes several cycles in one second is called frequency, and it is measured in Hertz (Hz).
the conversion of DC voltage to AC voltage is a common problem. In any circuit, we can observe that if we design a circuit that takes the AC input and gives DC output. But, if we want to change the circuit from DC to AC, a DC to AC converter circuit is used. The inverter (converter) is frequently required in the circuits like where DC to AC conversion is not possible. So, an inverter circuit is employed for converting the DC to AC converter.
PS : Dear friends, the ammeter connection shown in this video is totally misleading. You should connect an ammeter in series manner with the circuit, I was completely messed that up. But it will not affect the core idea of how to convert DC to AC. Ill upload the corrected videos ASAP.

Your honesty is appreciated !
Yes
Sir I have a doubt ...will the current produced be enough for a electromagnetic induction ...as I'm trying a project on mutual induction like the one in transformers ...but a little simple one with 2 coils placed one over the other
I would really appreciate your help🙏🏻
Next to that you cant convert dc to ac in the first place.. since ac is a pure sinus.. You can generate a pulsing artificial sinus tough.. You do convert ac to dc yes.
Next to that, that modified sine wave was btw the simplest of its form, and is more an example of a pwm signal.. A good ac generation consist of multiple square-waves where each one follows the actual sinus, so its not just two pulses of dc like you described anyway it consist of a few dozen of those all having a small intervall, having all their own amplitude related to the momentary voltage.
Been studying electronics for about a decade on and off. The good thing is, things haven't changed much. Sure, we have better memory and faster more complex chips. but the gist of it hasn't changed in hundreds of yrs. I still find myself exploring diode functions, resistor functions, ect ect. Well made video. Thx.
We need more people like this. This is a helpful instruction. I am 12 and my father is an electric engineerer and we are both very intimated.
bro plz use proper english because intimated means you want to reproduce
Superb 👍👍👍
Thank You! You have no idea how much that helped.
Glad to hear it!
Your videos make our life easier. Thanks.
Nice presentation sir. Looking forward to enjoying upcoming videos.
Thank you , and keep watching.
Wow. Great explanation. It clarified how few electronic devices work.
Glad it was helpful!
Dear Prof MAD......!
What a wonderful day that I came across your loved and simplified Electronic Lessons..! I even gained beautiful English Lessons from
the way you spoke.I have had difficulties in getting the meaning of the AC Trigonometric function for over 11 years. I am now able to
understand the ""down flow of waves "" mean to be the Negative Pol.Thank very much: Sir.
My pleasure!
Great video ! Well explained, easy to understand... Very good job. I have subscribed to your channel.
Awesome, thank you!
Great video. Very easy to understand.
Excellent
This was very interesting and informative.
If you wanted to have a better sin wave you could use capacitors or inductors that will smooth the wave form to more closely match those of a sin wave
Sir...your lectures are awesome 👍🤩 Mind-blowing...need more videos about electronic and electronics...I am a EEE student
I will try my best
So good
Osammm hy
Great video ! Well explained, . Very good job. I have subscribed to your channel.
Awesome, thank you!
Good video thanks.
Lol in 2024 and this is the first time I really understand. What's the H Bridge 😮
Listening the DC to AC for more than 10 years but never understand how it works 😅
Thanks you bro !
Well that Ammeter really ought to be a voltmeter. The snag is that we want to use the terms "Alternating" and "Direct" Current. It always seems worth the while to show the origin of this with a magnet spinning near a coil. The speed of the motion gives the frequency. Its the voltage output polarity and extent of it during the cycle that is so informative. So is the notion that without the changes it won't work! Now with that done we can move on to describe that in basic circuits - say lamps and heaters - it won't matter. Then we have the spin off that is induction which allows us to step the voltage up or down (transform) and is is so useful. NOW we can embrace conversion from ac to DC and vice-versa.
So good to see you ❤
Thankful good information
That was great!
Encontré Oro, Mil gracias , ahora comprendo un poco más el Panorama xD
Nice to hear that.
ขอบคุณครับ..ที่ฟื้นความจำจากตำราเรียน ในวิชา อีเล็คโทรนิค ตอนการสร้างกระแสคลื่นรูปฟันเรื่อย ซอทูช ในวงจรภาคกวาดเส้น ทางแนวตั้ง และทางแนวนอนในระบบ ทีวี สมัยก่อน ตั้งแต่ ทีวีขาวดำ แบบหลอดสูญญากาศ...
What a perfect explanation 💖✨
Glad you think so!
Love for your knowledge
Great video. Thank you for the information
Our pleasure!
Very good explanation, I liked it!
Glad to hear that!
Thank you!
Long AC power lines have more resistance (c.f. skin effect) but also have impedance and radiate energy (an effective antenna for 60Hz is 750 miles. The Pacific Intertie is a 500,000 volt DC line from Bonneville Dam in Washington carrying 1500 Megawatts to Los Angeles. The conversion to AC was originally using raquetball court sized Mercury Thyratrons and a field of inductors and capacitors.
I worked for Manitoba Hydro (technician, not engineer) just after they built their first DC system using Mercury Arc Valves. I was still there when they switched over to Thyristors. Big job, interesting stuff, although some of it pretty complex for a tech to understand.
Best information thanks 👍
Thanks for liking
👍 Good Job
Thanks!
Thank you very much
Thanks sir for your informational video
Thank you.
Vera level 💯
Thank you.
THANKS FOR YOUR SHARING SIR
Most welcome
👍🏻 Well done.
The peak to peak voltage (amplitude) will be greater than the RMS value.
Sinusoidal PWM control of the H-Bridge is worth a mention.
The dead time (Modified square wave) is introduced not only for a better approximation of the Sine wave, but also for the protection of the transistors as they could short out when toggled.
Very nice video tutorial. 👍
Thank you
That's interesting... What application is this?
Wow❤❤❤
Good
Thanks from iraq 🇮🇶 😘
Thanks man you helped me alot 😊
Glad to hear it!
Hello!
Ampere meters are NEVER connected in parallel with the consumer!
(time: 1:44 --> )
You can draw the same diagram by measuring the tension :)
He knows, he mentioned that in his pinned comment
Thank you bro.....
Thank you bro
Thanks for your Good Explanation
Glad it was helpful!
I was taught in elementary school (1970s) that current flowed from negative to positive. "Conventional" flow in drawings always drove me nuts, but we are stuck with it. LOL.
very good video and very well explained
Glad it was helpful!
Gustavo from Maceió- al - Brasil, novo no canal!💥👍💥
Good animation, new suscription.
Awesome, thank you!
Should the Amplitude not be ~170V? (120V * √2) as far as I know they have 120V RMS in america.
It is very good and exellent
Thank you
Good Morning Nice lectur
Thanks and welcome.
I always made a colpitts oscillator and attach it to a current amplifier. It makes for a very clean oscillator.
I believe the inventor of the rectifier tube was Rogers in Toronto, Canada.
9mts L8tr i still have no idea all i got was switches & waves isnt it a copper coil wind that reduces the voltage ?
ont good
It would be good if you guys toned down that annoying music so that it's easier to follow your explanation.
great video❤️❤️
Thank you!!
Awesome video. You explained the conventional and present means to describe current flow, current flow in general, and the different kinds of AC wave forms. These topics are rarely covered in these kinds of discussions, well done. I would like to have seen how capacitors are used to create the offset since wave, I suspect that the result is truer to sinusoidal waves than shown.
Hello really good explanation
Hey, thanks!
Really it helps to understand better way
Thank you.
Wow
Hi, I Like your video. Thanks
Hey, thanks
Crazy how that impatient freestyle go so hard!! Simple beat, nothing extraordinary🤷🏻♂️ it’s DRAKEOS, word Play so dangerous 🤟🏼✊🏼
Great video. Please don't forget that most of the world is 220/240V 50Hz, (and US houses are supplied with 240V).😊
Many many thanks
Most welcome
i guess its more posible to use volt meter rather than ammeter on that parallel connection, it can also show positive and negative reading if its only to show the polarity
I had never been instructed that current flow from DC to AC anywhere other than in a cell or battery. - When connect to an external source, the flow is from the negative terminal to the positive terminal (with the positive terminal being depicted by a short line and the negative terminal depicted by a long line). Fyi the AAA, AA, C, & D are dry cells when by themselves and are only considered a battery when used in conjunction with another cell.
The conventional direction of electric current was originally taken to be from the positive pole to the negative pole of a battery through the external circuit. This system is still used, and causes no problems, even though we now know the electric current is caused by electrons drifting from the negative to the positive pole. Incidentally the speed of the electrons is so slow that, for example, a flashlight battery will probably run down before an electron has gone around the circuit even once.
Thank you for sharing this.
A Lumped Element Model is used to describe circuit schematics and electron "flow"
The truth is, it's the movement of the EM fields that brings the fun to the party.....but parsing that out each time troubleshooting takes place would mean nothing would get done.
"Electron flow" is a lumped element type of shorthand.
@@WaterproofSoapagreed, I think actual electron flow is something like 1 foot per hour, or some ridiculously slow travel time.
So what is the difference between a simple switch and an igbt?
As you say still igbt need a swiching to change the current
What ai website are you using to generate voice?
Good and knowledgeable video..I have some questions and queries related to this video. 1. How much positive voltage we have to apply to base for current to flow through collector and emitter? 2. How we can control the current flow between collector and emitter by applying voltage or pulse to the base? I am very interested at knowledgeable video with good explanation so I am looking for to you kind, fast and fruitful response.
1. Since we are working with high power applications, normally we use IGBT (Insulated Gate Bipolar Transistor)s for switching purpose. IGBT's applied VGE (gate-emitter voltage) should be at least 14 V (preferably 15 V). Its better to check the data sheet of the component. .
2. I have made another video to explain how does the transistor work.

I hope this will help you.
I was taught in the military which teaches electron flow, so every once in a while I mix it up with the positive to negative flow. It is a hassle sometimes.
muito bom os videos
Obrigado
Could please explain howmuch voltage should be apply to the gate terminal
Great video but you need to upgrade your switches to IGBT so you can generate more frames per second :D
Ok, thanks
If the direction of the current is not important, then how does the diode work in a circuit if the flow of electrons are from the negative side to the positive side ? .
In ac does live and neutral wire interchange?
just a heads up, the voltage of a wall outlet is actually 120v rms so the amplitude of the sine wave would be closer to 170v, not 120v like you said in the video
Great how the ampmeter is connected in parallel
You are not Prof Mad 😅 at all. Nice explanation
Thanks 😅
thanks a lot
Happy to help
Kya igbt lagane se transformer ki jarurat nahi hogi
Thanks
Welcome
Great video! Extradinory Explanation , Enjoyed a lot by watching. Helped me to understand easily. 🙌❤️
Glad you liked it
Very informative . But i have one question here.where we connect the AC out put after all this process ?
Anywhere you like
Luar biasa from indonesia
Thank you.
Sir how control ckt work?
I say to from Bangladesh ❤
Good presentation, pity about the noise.
Thank you.
The transport category airplanes I worked on for twenty years or so had battery powered dynamos to produce AC. They worked OK.
Hi @Provmad, where can i find a arduino bpard to build this cercuit at home?
I am learning for electrision but want to expand my u derstanding of electronics
Is it possible to produce pure sine wave instead of modified sine wave (or PWM) in DC to AC inverte process?
Yeah there are pure sinewave inverters, Its depend on how far we need to smoothen the wave.
07:56 I think diodes should be in series not in parallel with IGBTs.
What with triangle-waves?
Using PWM inverters, better sinusoidal waves can be acheived
Yeah, its one method.
How can single phase voltage , be converted to 3 phase?
