nice vid. it made more sense than other channels. what would have helped me more is if you did not use an arduino or whatever with the triac and demonstrated a more simple circuit, with minimal components. ppl like me look for videos to help actually make a circuit, and go back to that same person who makes those videos, to find other useful information, if they demonstrate what they are talking about clearly and easily and if the circuit can cheaply be replicated at home. some people like me are not interested in using an arduino or whatever at all or for particular circuits. i think it would benefit everyone, including yourself, to incorperate a non arduino version of whatever circuit you are making , aka have both an arduino and a non arduino version of the circuit in the same video or even in seperate videos. resturaunts usually have more than one meal to choose from because they know not everyone likes the same thing. nice work tho on your specific flavor of videoing. have a good one
Mind blowing teaching, if this tutorial was not available on UA-cam, i would never be able 5o understand how triac is used.
Lol, I know you know greatscott released a similar video today, but it is hilarious that you guys did this independently, and at the same time. I even got the notifications at the same time.
Great video, as usual!
Thanks for the video. I’ve learned a lot from this Basic Component series.
your videos are an excellent bridge between theroy and practical applications .
Same project as great Scott's you guys are awsome
Thank you!
I asked the same question in both channels, ja!
This tutorial is more clearer than greatscots tutorial.
This tutorial is more clearer than greatscots tutorial.
Came from Great Scott! and this channel covered this subject way better. Cool, and thanks.
This is the first time I had an in depth understanding about the functionality of a thyristor and a triac
We need more and more electronics basics tutorials to understand each and everything you make and teach in your circuits and apply our efforts too..
Great inspiration for elctronics lovers.you make electronic more intresting thank you
Love from 🇮🇳
You and Great Scott Made the same video at same day. 😜
electronoob greatscott electroboom are the best EE channels
The world's best teacher thanks
Best video I've found about Triac and thyristor thank you
The best teacher ever
I love you for making these videos.
Right on time with my assignment!
thank you for that educative video..I support you from Tunisia.
Thanks
Really nice job, by yourself!
Good video mate
awesome explanation! 💪
Useful video 👍 very good
1:59 Actually, in a SCR we can't directly control the turn-off, only the turn-on.
5:40 Reducing the voltage by one half (50%) would actually reduce the power by one fourth (25%): p(t) = v^2(t)/R.
Thank you friend, very helpful
I blew up my power bench before I watched your video, definitely learn something here. GG
learned a lot! thanks!
Very nice project.
Good work 👍
Great video !!!!
I would love to work on power electronics. thanks for such a videos.
As always AMAZING...
DO MORE VIDEO ON THIS BASIC COM0ONENT TOPIC...!!😎
Best explanation❤thq
please make more videos on basic components and also on DAC,ADC😇😇😇😇
Great videos....
Very good
Pretty nice! 😃
I found a huge collection of thyristors and triacs and diacs on the attic..... you explained thyristor and triac very well .. .but i missed the diac component .....
Thank you Sir, pls we would like video on Transistor, how it work.
Great nice exelent
Banana for scale in the background... Nice
5:35 - AC power control using TRIAC by contring ZCP and Firing angle of Gate pulse.
thanks !
Super bro
You know how much you helped me ?! Thank you
I had a question? what is that optocoupler for zero crossings you using?
i have some problem with them
Hi. I'm glad I've helped you. You the the name on the schematic
Next video for basic of BJT and MOSFET
agree
Please make a video on mosfets and bjts. I've studied thembefore but never have been able to understand how can I implement it in my projects involving arduino.
Great Tutorial !!!
I used similar circuit for controlling Fan speed,but by this method fan makes hamming noise At lower speed. How can I remove this noise
I wouldn't suggest using a Triac to modulate (control) the speed of an AC motor. The construction of the motor was built expecting a Sin wave, not a modified pulsing Sin wave. There are other ways to control AC motors.
Hi, great video. I'm wondering here if it would be possible to make a three phase inverter using 3 Triac. But to control a motor it would have a lower power factor.
Nice
Hello, Thanks for nice article first. I want to know when to choose SCR/TRIAC over power BJT, MOSFET?
Please make video on Space Vector Modulation
You need to revisit this subject again but this time my request is you add LPF to the output of the TRIAC am curious to see how the waveform would turnout.
#awesome
Plzz did u check the open avrc transmitter project plzz make a video on it
What's the difference to for example using transistors and diodes? Since you need some kind of timing circuit either way, what does the thyristor save you?
Sir alsk please make a videk on power bank pcb made by yourself
Great Scott video is good but too fast for me
So I came here
How are able to observe the load voltage with dso as both having ground reference? From my knowledge i guess we cant observe ac mains signal directly and should use a transformer to so do.
So how do old dimmer switch’s control the triac? I’ve torn them apart before and never seen any thing like a micro controller in them. Is the gate being fired by the 50/60 Hrz wave? I’ve been wondering about this for awhile.
For the analog version of TRIAC dimmer just search a circuit with a DIAC and potentiometer as well. Is very easy. The Diac will apply the firing pulse each zero cross
Hi nice video, I have a dummy question hope you can help me, I would like to watch the signal in my oscilloscope, but i have fear about a bad connection, could you help me to know where it's secure to connect Chanel 1 and 2?
Can I use this for control my 2KW room heater ? Or my 1HP small water pump ??
Waiting 4 ur answer :)
At 2:10 you say a thyristor stays on until the current changes direction in a DC circuit.
I must be using Thyristors wrong. I have been using the Gate to control it like a switch. Ground the Gate current stops. Make the Gate positive and the Source Drain current flows?
Have I been doing something wrong... It work beautifully for me. I use it to control windscreen wiper motors. IR1010E Thyristor.
which simulation software you are using to express your simulation
We can control speed of an universal motor by using the circuit
Hi I tried this circuit with Arduino.but the ac load(15w) bulb is not at all switched on!! I used pc817,moc3023,bt136,10k potentiometer,1amp bridge and all the required resistors.what could be the issue?
Bro! i am a great fan of u.I love ur voice n all of ur videos. But this is not that great for me to follow.maybe it is just my problem in following. Anyway a quality video as of always. Keep growing
What can I do in 220v PID temperature control temperature is stable 30^c more then set temperature.
Please reply me back.
Your understanding is highly appreciated.
The LED doesn't need a diode to block negative current...
Sir can you make this to countrol with it remote? Please reply
Hi! I tried with 2 thyristors connected reverse together so that make an Triac. but it didnot work. Can somebody help plz?
can you control 3 phases?
Can we control ac motors?
What happens if you connected two triacs in parallel?
Q : ok what is the variable resisters value aka potentiometer -- 10 K? A: Yes, 10 K.
This circuit works perfectly well with small AC BLDC fan i.e. 220V and 0.12-0.16A as well. I have tested. Ensure no faulty potmeter to start with as first step in troubleshooting if you did not get result. Secondly, the connection between 200OHM reister and mains is important. By mistake, do not connect mains directly to pin no6 of MOC3020 or 21. It can have magic smoke..!!! Carefult...
phase fired controller
what is an EMI noise of such circuit?
Have you ever work for nasa
Why the need to use arduino? What the gain? Using a Diac in Triac's gate, won't do the same?
using your t12 soldering iron circuit but i want control using a potentiometer so i want to change the code the potentiometer Connect to a3 of arduino
so the Arduino control circuit will work with ANY Triac? No matter the specs for the Gate?
No, you must size the optocoupler (or firing element) and gate resistor to the TRIAC specs, bigger TRIAC/SCR require more trigger current in the gate.
@@tejonBiker Quite so. Perhaps you could make a Part II to discuss this in detail ???
Finally one of the first comments
shouldnt waveform be other way around? flat part when triac is on cause of voltage drop across the load and curved part cause there is no voltage drop? Thats how it is on my set up. unless its current what is on scope there.
If i saw this video a would of never shocked the shit out of me with raleys.
but does this work with ac motors, what the difference would be?
AC motors need more advanced control procedures. They are not like DC motors where everything is naturally decoupled. In AC motors if you change just the voltage with out taking in consideration other aspects other parameters will change and this would cause a problem for the motor itself. And that's there is something like the scalar control V/f or the FOC methods
@@abdelssami partly understand but not fully, thanks for your answer. will search for more info. thank you very much!!!!
Will you sell this project
Hello sir i have simle & great idea can you please make paper powerd rc plane using digispark arduino.and android app..just control motor speed and direct..
bro i want t12 solder station
Is it me or did someone else notice the banana photobomb this video.
You took an entire 1:30 for the video to start
There is a problem in notification of video that's the reason I think you got low views iam also your subscriber 🔔 I don't receive your video notification I found your video after 6 days by coming your home page
with a Diac and an RC to control the firing angle there is no need for an arduino and software and all that stuff...
@@jmicroelectronics9742 although my comment was only about the dimmer in video but if I want to control the AC motor speed with temperature, I would use a thermistor in my timing RC circuit (or perhaps use it with a transistor current source plus a charging capacitor which will have the same result but it will be linear with time instead of exponential) and then this capacitor voltage will be used to trigger the diac which subsequently fires the triac. by the way I think there are triacs that actually have a built in diac in their gate internally although I have never seen or used myself
@@jmicroelectronics9742 first of all I am not against using computer for device control. Sure if you want to control 5,6, 10 different devices that might be also dependent on each other, then of course using a microcontroller is the easiest way to go. But for just one device, I'd rather a non computer based method which I call it analog way, using opamps, transistors, voltage ref, etc + innovative thinking and clever use of electronics! and that's just a matter of taste I think and not a rule. I was taught and trained in electronics in 1980's so we were more relied on analog solutions rather than using an expensive micro controller (and its surrounding logics) to control one lamp or one motor . In answer to your specific question, accuracy will not be any worse or better than the arduino based method for sure. With regard to controlling speed in a temperature interval only, it can be done by adding a couple of opamps and and comparing with variable reference voltages. Well, in very old days (1960's for instance) they would do it with transistor arrays and just differential amplifiers rather than opamps but of course it would be too messy.
@@amirb715 you are right using the analog methods would be more efficient than using a digital one especially for controlling a bulb, but I think that he is trying to show the HOW TO thing and how its work.
@@amirb715 Idea is to get to a working prototype using potmeter. See next article where in same circuit is used with PWM for control and you will be blown !!
help me
You speak very fast! Why are you so hurry? I must repeat and repeat the video to understand what you want to explain.
Please take it easy because we don't have a proficiency to english coarse.
You projects are good.
But english accent
Man you are speaking fast and sometime yr accent interfer. I am sorry did not like the narration
