What is a DIAC? How DIACs Work? (DIAC Tutorial)
Вставка

- In our previous lessons, I examined the working principle of Thyristor and TRIAC. In this video, I will basically explain the working principle of the DIAC, which is one of the power electronics circuit elements used in AC timer, also known as dimmer circuits and motor speed control circuits, together with the TRIAC. The abbreviation DIAC is used as an abbreviation of the English Diode for Alternating Current. It is understood from its English name that this two-pin power electronics circuit element is used in alternating current.
Thanks for sharing, very informative.
Nicely explained!Thx...
Excelent video. Regards from Panama 🇵🇦
Thank you so much 😊🙋🏻♂️
Nice information
Excellent information for someone who is serious about learning
Thank you so much ☺️
Thank you
Thank you.
Does it conduct only voltage or also current?
Thank you for your nice sharing, but I have a question, in dimmer circuit if we dont use diac what will happen.
Hope response from you.
Thank you.
خیلی در آموزش کمک کرد متشکرم از شما👍👍👍
خوشحالم که مفید بوده متشکرم. ☺️🙏🏼
1:29 "it is mostly prefered in AC applications" . Can we use it with an DC applications?
Would the circuit @ 3:05 Not do the same thing without the DIAC ? If the values of R and C were chosen correctly ?
What if i replace Diac for Diod zenner ?
thank u
Thank u!
I am new at your channel.plz tell us that difference which is used for voltage regulator MOSFET and a MOSFET use for only one touch then MOSFET sill ON supply
nice
So what would be the use case for such a component, does it basically just allow for the AC wave to be duty cycled ?
it kinda does it. it cuts off parts of the AC. for example, it cuts off the first 25% of a full wave
Excellent 🆗
Thank you so much 😊

Schade das die Übersetzung immer einen zu großen Teil des sichtbaren Inhalts abdeckt. Ansonsten alles gut erklärt 👍
Danke schön ☺️🙏🏼 Sie können Untertitel in den UA-cam-Einstellungen deaktivieren. Das Video selbst enthält keine Untertitel.
There's a huge problem in your timer example.
Whenever the diac triggers the triac, current starts flowing from capacitor to the load (not from the ac source) as at that time the ac source is at zero point.
Pin my comment.
That is NOTHING like two diodes in parallel. I wish you provided a correct explanation, because I still do not know what it is, I guess I'll have to hit the books. :(
If you don't understand something it is not because there is some mistake! A diode won't conduct until a certain voltage is achieved, usually small like 0.3 - 0.7V. In a diac this is a higher voltage as stated 25-40V, so in one current direction it will suddenly conduct. The same ting happens in the opposite current direction i.e. in the other half of the cycle, so it behaves like two diodes with a high breakdown voltage in reverse parallel. The purpose is to provide a sudden pulse of current to some other device e.g. a triac, every half-cycle.
WELL SAID GEORGE!
@@karhukivi "The purpose is to provide a sudden pulse of current...". Ok, so in the example (a dimmer for a lamp I guess), this circuit is limiting the A/C current to the lamp to only the times when the voltage is between 25 and 40V (of the sine wave)? Is this somewhat similar to a DC regulator? To the end user (the owner of the lamp), it appears that a constant dimmed brightness (let's say 1/4th of the brightness due to the 30V capacitor) is achieved and since this is an A/C bulb, we have to use a strategy (like the one provided) to allow current in both directions while providing a smaller amount of current to the bulb... does that sound right or did I get it wrong?
Nice #shoaibelectronicstech
