I am working on project for my college which is to automate heater rod, basically it has two inputs: temperature sensor input and potentiometer value as reference, we initially thought of using microprocessor but later thought what if we use an op amp instead of it. But we felt the op amp would struggle when the input is near reference as you have pointed out and it wont turn off at all. is there a way to use op amp and not comparators in this project? op amp is readily available in lab. Your videos are very helpful for searching the answers to questions that i had. Your way of explaining all in one go and your pacing is really nice... i enjoyed learning with you.
Good luck in your studies! I recommend watching this playlist from the beginning which talks about circuits: ru-vid.com/group/PLfYdTiQCV_p4IKgfbRML5EHFJPfBdW9Fv After that, I'd recommend watching the first 10-15 videos in this playlist, which talks about microelectronics: ru-vid.com/group/PLfYdTiQCV_p711DywXAh53wL3xI7S55lg And after that, I recommend exploring to see what best fits your interest! Microcontrollers or control systems. We're hoping to get digital logic videos up relatively soon as well as AC circuits but while we're working on them, we have several open source textbooks on circuitbread.com that you can explore to see what catches your interest. Enjoy!
@@CircuitBread hey there, I had a question I wanted to ask on Reddit but my karma was too low. How do IGBT’s make a pure sine wave for 60hz? I understand that they switch on and off many times and the more they do that, the average looks more like a pure sine wave. If they only switch on and off 20,000 times a second and pulse width modulation works best when the pulses are extremely fast, how do you generate 60hz of ac?
