Просмотров 134Месяц назад
An optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an optocoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED. Both parts are contained within a black box with pins for connectivity. The input circuit takes the incoming signal...

Просмотров 83Месяц назад
Voltage follower can be defined as when the output of the op-amp circuit follows the input of the op-amp directly. So both the input and output voltages are the same. This circuit doesn’t supply any amplification. As a result, voltage gain is equivalent to 1. It is also known as unity gain, buffer & isolation amplifier. This circuit has high input impedance so it is used in different circuits. ...

[27]BIFILER COIL UTILITY
Просмотров 857 месяцев назад
When used in a switching transformer, one winding of the bifilar coil is used as a means of removing the energy stored in the stray magnetic flux which fails to link the primary coil to the secondary coil of the transformer. Because of their proximity, the wires of the bifilar coil both the same stray magnetic flux. One wire is clamped to ground usually by a diode so that when the other "primar...

Because unregulated power supplies do not have voltage regulators built into them, they typically are designed to produce a specific voltage at a specific maximum output load current. These are typically the block wall chargers that turn AC into a small trickle of DC and are often used to power devices such as household electronics. The DC voltage output is dependent on an internal voltage redu...

SG3525 is a pulse generator IC how can you use this IC in audio?
Need ur contact number for advice
you can contact with my mail, it is in my channel.
Very informative sir
So nice of you, keep watching. Thank you
Sir when we designing a voltage divider circuit to measure voltage by arduino do we only need to consider voltage ? What about current ?
no you see my resistance network video. you can get your answer
@@hobby_plus thank you sir
Hi Sir, which software did you use?
witch software do you to know?
@@hobby_plus for drawing that circuit diagram
@@hobby_plusi need to know what is the software you used to draw the schematics ?
@@vishalr4551 kicad
Yes it's helpful to me...❤
Glad to hear that
Sir can we used resistor network output to another optocoupler and measure the voltage without using a transformer
yes it will also work.
@@hobby_plus great sir . If you have time please make a video for that also sir 🙏
@hobby_plus Dear teacher, you explain that there are different grounds in this circuit. You mention this at the end. However, from the beginning, I realized there was an issue with the grounds. Therefore, I was confused throughout the whole lesson. In the follow up video, please discuss the circuit, from the perspective of the different grounds. Thank you.
I will make a video with a complete circuit. then there is no confusion with ground.thank you.
no you see my resistance network video. you can get your answer
Sir when we used the resistor network to calculator voltage we need to connect both GRD1 and GRD right ?
yes. you should do it.
@@hobby_plus sir will that have the risk of damaging the arduino ?
wait for my next video, it will batter for clear confusion.
@@hobby_plus thank you see . Waiting for next video
Hi Sir, which software do you use for circuits
witch software do you to know?
Name of the software you used to design that circuit on?

Please wait for some day i will to make a video on this topic, thank your request. you can get my mail ID in my chanel.
Khub valo.
thank you
Btw sir with optocoupler output it might possible to measures the current but how to measure voltage
witch voltage do you want to measures, output or input?
@@hobby_plus i need measure input voltage by output of the optocoupler by a microcontroller
I don't understand your question?
Thank you sir ❤❤❤
Please explain half bridge SMPS with transformer design
I will make a video on this topic, please wait.
Sir do you know how to isolated voltage measure with optocouplers
I an sending you a link hope you can get your answer, if ti's not then tell me again. thank you for your en-quarry. ruclips.net/video/9xVl-Xdbg5M/видео.html

Sir if mosfet need 12V to drive the gate how to create 12 v by 24 V
tell you shortly
@@hobby_plus thank you sir
you can use 1) Resistance network. 2) 2:1 Driver transformer. 3) by the transistor as a amplifier 4) by the op-amp (low amp output) Driver transformer is the safe way to drive MOSFET. According your circuit requirement you can use it.
@@hobby_plus thanks a lot for your response sir
Why voltage is doubled to 620 V at point 2
220 volt AC is = (220 X 1.4142) DC = 311 Volt Approx. It is constantly present in the circuit. But when transformer is in ON mode (Mosfet in active mode) electromagnetic field increased. When Mosfet is in OFF mode electromagnetic field convert to voltage and it is 311 volt. respect to ground you can get 622 volt in Point2. Because 311 volt (DC power) still present on the transformer transformer. So 311V + 311V = 622V. That is 311V DC power sources in series.
@@hobby_plus Thank you but still not clear, at pt 2 do the voltage doubles ehen MOSEFET is On or Off, and why it should double
@@MUSTAFAJOMAA I will make a video for that ok.

You are not good teaching
WHY? what happened?
Thnks sir
Isn't the threshold voltage a _3.5 instead a +3.5?
YES, I AM SORRY. Thank you.
In the output you draw pwm very clean.mayby I I am in wrong.pleas teach me😢😢😢😢😢😢😢😢
can you have sent your C.R.O. pic through mail? my mail id is rya.subha@gmail.com
in the last night I test this circuit in my lab, output was test with digital oscilloscope. I saw the output is perfectly squarer web in time of work also and it is working properly.
Master this event not accur .why.becaus when d.s go go to zero voltage in seconside go to zero .definitely the shape of pwm is changed I try very but about under duty 20% voltage go to 0.
it is not clear to me. can you tell me in detail?
Hi❤❤❤❤❤❤❤hi master
hi

Do you get my mail ID?
Hi my dude. I try for many week make trans pulse to isolate my switch ic and in ic side use 12v 3 amp to have a good pulse on the primary for trigger in half bridge 20 mosfet.please help.
I don't understand what you say.
For 24 DC volt 1.37 amp LED panel what will be resistance values.
first of all you have understand with transistor sued for that. In my video I already tell you how can you calculate the resistance value.
Why not just a current limiting resistor?
Very good sir
Thanks and welcome
Good Go ahead..

मेरा निवेदन ये है कि भारत में अधिकतर लोग गांव में या छोटे से इलाके में रहते हैं जहां हिंदी भाषा ज्यादा चलती है ,,तो आप भी हिंदी भाषा में इसे बतलाऐंगे तो आपका ये ज्ञानवर्धक चैनल अधिक लोगों तक पहुंच पाएगा ओर मेरे जैसे हिंदी भाषी ओर ऐडवांस सिस्टम टैक्नोलॉजी में कम समझ रखनेवाले टैक्निशियन भी इसके बेसिक कांसेप्ट को समझकर आसानी से काम कर सकते हैं ओर आपकी बात सभी तक आसानी से पहूंच जाने से आपका अधिक लोगों तक ये जानकारी पहुंचाने का मकसद भी पूरा हो जाएगा,,जय हिन्द
आपने बहुत ही जबरदस्त तरीके से बतलाया है,,,पर ये जानकारी पूरी तरह से इंग्लिश भाषा में होने से इसे मेरे लिए समझना मुश्किल था,तब मैंने मेरी बेटी को पढ़कर समझने के बाद इसे हिन्दी भाषा में ट्रांसलेट कर मुझे समझाने को कहा,,तब ये मुझे समझ में आया,, धन्यवाद जी
