The triac is an electronic component composed of two thyristors mounted head to tail, the two thyristors share a common terminal called the G trigger. The triac allows current to flow in both directions (each thyristor allows current to flow in only one direction) when a predetermined control current is applied to its trigger.
BT152 is an Silicon Controlled Rectifier (SCR). From what I can see in the circuit, the two burnt diodes provided power to the low voltage power section for the logic circuits. The SCR is turned on via the logic circuits and provides full DC unregulated power to the + side of the relays and probably the lamp too. When you shorted (calibrated fused) the two burnt diodes, it provided power to the anode of the larger diode which then provided power to the + side of the relays. At least that is my best guess from what I could see of the circuit in the video. Great job.
Yup. I too replaced the transformers with SMPSs to reduce power consumption in just about every device around the house where possible/practical.
Brilliant. You shorted the 2 rectifier diodes so that the circuit can be powered by DC power supply instead of AC transformer.
@@ChupoCro And If I remember correctly bridge allows to connect DC on any polarity. It's common for 24V systems to be both AC and DC so it could be this option was even specified in this garage opener documentation.
Wow! Sorin your garage door opener and mine died the same day. We had a bad thunderstorm here and lightning struck nearby - took out my garage door opener, TV, internet modem, a circuit breaker in my panel box, and an alarm clock. I found a new control board for my garage door opener on ebay and waiting for it to arrive. My transformer was very hot too but mine is built onto the main circuit board. I found an EEPROM that had 56 ohms from the VCC pin to ground. Not sure if I can just replace the chip because it may have code in it, or it could be the EEPROM that stores the program info for the remote controls. Thanks for sharing how you got yours working again!
Excellent work, maybe you can fit a led instead the burned bulb
I think in this case the BT152 Thyristor is used as switch to put the positive voltage to the motor. In this case it will also help to prevent sparks in the relays. Relays are used to switch the polarity to the motor and also for switching the light bulb. The same priciples were used in my own project for double wing doors, but instead of thyristor i have used power mosfet n-channel transistors.
Pulse turns on Triac and a Triac is a bidirectional, three-electrode AC switch that allows electrons to flow in either direction. It is the equivalent of two SCRs connected in a reverse-parallel arrangement with gates connected to each other. A TRIAC is triggered into conduction in both directions by a gate signal like that of an SCR
Hi Sorin you never cease to amazed me with your electronic knowledge. Great Video. Thsnks for sharing.
a triac is like an ac mosfet it can switch with a pos or neg pulse on the gate
Ive never heard of one of these going bad. Yours must be made in England. Yes, I stole that from "The I.T. Crowd" LOL
I think, the triac is used to lower the speed of the motor at the end of closing
I see end of vidéo, and I think i'm wrong 😅
Garage door have constant speed.
This was enlightening and a fun workaround. One question I have is of how the triac works with dc if it’s an ac component? Always read the comments to learn, thanks to those who put some really interesting info, but I didn’t find this asked or answered.
@@ChupoCro thank you for taking the time to reply with such a detailed description. I found it helpful 👍
Ι fix some like that... Its garage and take over 80 car open and cose at list 10 times per our... People come and live ol time... The power its 24v. 5A and burn in 4 months... I change to 24v 15A ... 3 power supply in parallels mode its work 1 year and its fine... The motor its 12v ant take very amps in the start after that its not problems.... If the door work hard i think you need second suplay in parallels to take more Amps ... Thenks for this video' i love video'you fix and sory for .my English
The triac is used to supply current to the logic circuit which later activates the relay which takes over the motor load! By modifying, you probably supplied power to the logic circuit after the triac, so everything works as it should!
@@ChupoCro Da se ne zahebajem na engleskom, cesto popravljam pumpe za vodu i u njima triac sluzi da preuzme ulogu releja na sebe nekih par stotinki, napoji logicko kolo i izdrzi udar struje dok se ne aktivira relej koji onda napaja elektro motor vodene pumpe! Cinilo mi se da mu je primjena ista ovdje! Mozda nisam dobro napisao na engleskom!
@@ChupoCro Brate iskreno i meni nije jasno, sta triac radi, kad Sorinu nije jasno sve govori! Ja koliko sam provalio na vodenim pumpama sluzi za to da izdrzi inicijalno pokretanje motora dok logicko kolo pokrene relej i onda ja tricu ne vidim nikakvu svrhu poslije okidanja releja, ali je logicko kolo sigurno napojeneo preko njega na startu, naravni grec pa onda kolo, okidanjem releja sve to sjedini u jedan vod! Tzv gate na triacu je spojen na 330 oma otporniku koji je odmah u funkciji kad se napoji iz utikaca... Ja imam problem na elktronikama vodenih pumpi jer su zaljevene nekim katranom i nemam bas kopletan uvid u shemu, rovim katran do komponenti i kad vidim koja nije u redu nju zamjenim i tu zavrsavam sa istragom! Pokusat cu naci koju sliku pa mi mozda pomognes jer mi se desi nakon zamjene trica(naravno u BiH nikad ne mozes naci isti) da nekad kasni gasenje pumpe 3 minute nakon sto senzor pritiska kaze da sve treba ugasiti!
the triac appears to be connected to the other pin of the transformer and not in use for motor operation. What I have to think is for door opening signaling (lights and acoustic signal used on doors in community areas or on the street to warn of door opening) is optional.
Or for a emergency battery system (optional to) can open doors in powers loss.
Is difficult to say without studying the board and without having the connection manual.
Maybe y lost something but the transformer have (for put simply)
L1 ground L2 he only connected L1 and ground and the triac is in L2 so how can work the motor with no power in.
And you don't need two of them to control the two options forward and backward.
Is it connected Maybe Is a delay, is activated from the relays so you don't get a short circuit when change polarity.
The triac limits neutrino emissions from the deflector shield obviously !
The diode will be replaced in the next video, part 2. :D
thank you so much, your video help me so much.
Thanks again for the vidéo, perhaps the triac is use to protect the board, it cut the power if something gone wrong.
Triac might be a soft starter.
Whenever Sorin use the word ''proper'' 2 or 3times consecutively, you must know he is getting into dodgy mode
Excellent job
i love when you say... 9:10 🤣☺☺
If it quacks like the duck, it's a tridack.
Proper calibrated fuse!
Truac is there For reducing the motor speed, iver the potenciometer
Hello🤝magic touch 👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋
Sorin, You are a wonderful tutor and I enjoy everything on your channel. Maybe you should consider restricting your wife from "button pushing"; Ha Ha. Have a great day.
Maybe it’s a scr. This would allow the motor to continue to run opening the door until it gets a signal to which opens the scr
Excellent good one sir
Tyristors and triacs can work with AC and DC ;)
Frikin love Sorin. His dodgey is better than mosts proper lmfao.
triac use to run motor contol circuit,it switch ac current through relay
To open the garage door pull down on the emergency release cord and then lift the door and drive out.
The red button is to insert the remotes
The Triac is probably for controlling the light separately from the motor. The light should turn on and remain on for a short while after the motor stops working.
I am thinking the same. The light is the only thing that wasnt tested due to the bulb burned out. Also the volt meter checks at the end of the repair showed insuffient voltage at the bulb socket.
Triac Incetineste usa de la capetele cursei
Good idea blame the wife when something goes wrong!😅🤔😳😂
Triacul reduce viteza motorului
Sorin has the hands of Jesus
It is not enough to analyze in your circuit why this was working in more info to understand but
I guess BT152 it is definitely thyristor becuase of you can replace two didoe It means gate to provide voltage signal that Ac to half rectified DC into gate pin ,and then diode made potential Vf but you can change diode dead to wire and it made gate voltage more before then about 0.7V
It means gate resistor and diode can make voltage divider more voltage growing up to gate
Becuase of thyristor derating heatting a long time so it can need more gate threshold voltage you can make wire it is maded gate voltage more growing up well.
Gate voltage it is low it make definitely not turn on thyristor but your thyristor definite in initial state in off state it means anode it is not different a lot anode -gate voltage
So it is always off because your thyristor gate it is not turn on leveling it is ambiguous reaching ,so you can need
More current into relay and relay can provide other diode in rectified source from anode to cathode
And then if it is triac , maybe diac it is needed to your circuits but I can not find out. So it is definitely thyristor BT152-xxxB
hi
sir how do you record video from micro scope
🤟😎 best mod!!!!
Don't garage doors have manual pull handles in case of failure or emergency.
Awesome 😊
its a thyristor.exellent job.i thing 24v 10a or 15a its better....
Sorin the triac was fitted as a red herring to keep you guess HA HA HA
for the light
Sorin come to Besiktas...Im always blame her... Things only broken when she use...ıt's just bad luck but It's most enjoyable thing for me to blame her...😀 Triac is for motor speed or temp control( voltage control)
👌👌👍👍
Am fost si eu sa repar o USA de garage la cineva, dar pe cand USA se ridica nu mai avea putere sa traga USA in sus si se oprea, numai daca anutam USA cu mana sa mearga in sus mergea.
Maby they had many triac in stock 😂 when they build it
Diodegonewild chenel👀
Where i can buy a popper calibrated fuse. Lol. 💣
les résistances peuvent être remplacer pars des petit fusible!!!
Honey, can you mow the lawn? no, the garage door opener is broken. Can you fix it? Ohhh...
😂 1:24
Hehehe Sorin "doesnt know" what is BT152 :D Lets see in comment section who is old subscriber who is new subscriber :D
Sorin, you should more careful when your wife touching you, maybe something bad happen, who knows.. 😂
❤Hello dear friend sorin. Today we have moved away from the laptop☕
SCR is better
