- Diodes are very versatile and can be used for many things and this time, we're going to talk about using diodes as clippers and clampers. Diode clippers are used to "clip" the voltage while clampers "clamp" the voltage to the a desired DC voltage. Clamping is a weird word to use in this case, so perhaps easier to say that a clamper shifts AC waveforms to the desired DC offset. Check out Herald's written tutorial on the CircuitBread website to get more in-depth math and a few more examples.

Also, you don't get as many verbal mix-ups as you get with Josh attempting to talk, so it's always good to review the written tutorial. And, if you want more videos on basic and intermediate electronics, subscribe to the CircuitBread channel!

i'm in First Year Electrical Engineering In Egypt And this was so Helpful
Thanks
Glad I found this channel, really clean and concise videos and I'm liking the style. I'm an electrical engineering student from the UK, it's a real shame our prospective salaries are so low compared to the US, it's driving a lot of my friends and colleagues into higher paying sectors such as finance or engineering management type jobs. I'm liking control theory the most and will hopefully try and move to the US once I've got something credible on my résumé haha
Hey Connor, thanks for the feedback! I wonder why EE salaries are so low in the UK because my understanding is that, on average, UK cost of living is higher than US. And there seems to be good high-tech opportunities there as well. Strange. But control theory is cool! I've only taken two classes on it and the first one was the semester my oldest daughter was born so I didn't learn practically anything but the second class made everything clear. Haven't used the knowledge outside of school, though...
I think in Australia electronic engineering salaries are also low. Electricians have more earning potential by far. Its crazy as you have to be very intelligent to get an electronic engineering degree. No doubt the very best get a good salary but what good id that to the average engineer. I bought an almost new power supply and signal generator from a young electronic engineer. I think he was changing career.
@@CircuitBread WHY THE F put that communist propaganda in the background in that video???!!! Are jewish?
Studying mechatronics and you are my go to electronics channel
Thanks a lot for sharing, really freshen my mind and my skill thats has been dusty for over decade
It's amazing how quickly the details of this stuff get lost when you don't use it. A lot of these tutorials require a pretty thorough brain dusting to bring ourselves back up to full speed on them.
The value of the first resistor at the beginning of video is ?? Thanks Mike
hey awesome video. very informative can you do a video on your electronics bench, like a tour of your bench and your setup. i want to setup a electronics bench station and would like to get ideas, and i love how yours is setup. thank you
Hey Allen! Fortunately, using my actual electronics desk for videos requires me to keep it clean. It used to just turn into a holy mess within a couple weeks with different unfinished projects. As for doing a video... sure! I never considered doing it before, but it should be pretty straightforward.
Great video. I'd like to try this an tons more stuff. What would you recommend for hardware for someone getting into Electronics? I'd like to purchase a wave form gen and an oscilloscope for my entry-level lab, but I don't want to break the bank. Should I purchased used equipment or purchase new from Amazon?
Hey Brian! While electronics testing equipment has dropped in price, they can still get expensive fast. I've had mixed experience with used equipment - I still use the benchtop multimeter I got off of eBay a decade ago (when it was already at least 2 decades old) but the 1980's era oscilloscope I got at the same time was so big, loud, and lacking in features that I got rid of it after 3-4 years. Depending on what you're doing, you don't necessarily need an oscilloscope. Sergey (who writes our PIC10F200 series) doesn't have an oscilloscope but uses a $5 logic analyzer he got off of AliExpress to do his embedded system testing. If you have more money and more needs, you could get the Digilent Analog Discovery 2 (o-scope, logic analyzer, and variable power supply) that's a little less than $300 but very powerful. JB (who has written most of our microelectronics tutorials) has that but I haven't asked him what he thinks of it since he got it.
How do I set my multi meter voltage to measure output voltage from 120v AC inverter transformer secondary, hooked to two "inverse" parallel 600v standard diodes through one load resistor? One diode on each line reversed. Is this final called DC half wave rectification or AC back and forth from 60 cycles Inverter output, still near 100volts? Or is this still AC output through both diodes.? Circuit was published about 2006 to operate inductor and resistance for 6 amps output. (Not dual clipper circuit- to be used as power source only) I need to know also why they did it this way, maybe as some type of protection from back voltage applied which is also there, higher than 120 volts.
Thank you very much
Hey thanks for these videos!
I am a hobbyist, and trying to replicate the diodes clipper experiments with one of those cheap XR2206 based function generators. My oscope shows a full sin wave output across the load, despite a diode in place (like you have), which should be half rectifying the input sin wave. No rectification occurs regardless of which way the diode is oriented. I am assuming my cheap function generator is not delivering true bipolar AC voltages, that are flipping positive and negative, that allow both forward and reverse biasing of the diode?
I guess my question is do "real" function generators output a sin wave (or sawtooth, etc.) that has true bipolar, positive and negative voltages? If so, any recommendations? Thanks!
Hmmm... that is odd! Yes, "real" function generators allow both positive and negative voltages and also allow you to put in DC offsets. Is there any way to check, with your oscilloscope for example, that the output is bipolar? It seems like if you attach your o-scope and function generator grounds together (which should already be done), your o-scope would show you if the voltage ever becomes negative.
great video
Hi. This is a fantastic video in understanding diodes with an AC voltage input. Thank you very much as i never understood this topic. I will build the circuit. It would be nice if you had the component values in the drawing. The resistor value is important not to draw to much power from signal generator. What range of resistors is acceptable ??
Hi Michael! I actually don't remember the value of the resistor, which is an oversight and something I should have explicitly stated, just as a guide. In reality, it doesn't really matter, as long as it's big enough to protect your signal generator. At 10Vpp, a 1K to 10K resistor should work just fine, as it will limit your signal generator to ~1-10mA, which is well less than most signal generators can handle.
If you haven't checked out Herald's written tutorial this is based on, it will probably help you even more: www.circuitbread.com/tutorials/using-diodes-as-clippers-or-clampers
Thanks for your reply. i will build the circuit shortly.
Great video. Could you do some videos on the Raspberry Pi 4?
Thank you very much!
Sergey is deciding on what to do after he wraps up the PIC10F200 series and he's currently debating between an FGPA/CPLD series and a series that gives overviews and first-steps of the popular embedded platforms, such as Arduino, Raspberry Pi, Beaglebone, etc. I think he's leaning toward the first but he may jump into the overview series after that!
@@CircuitBread Thank you very much
Cool
*👌*
Am I the only one thinking he kinda looks like a mix between Paul Rudd and Matthew McConaughey
I'll take either one!
free the poor toast😢
An engineer should learn practical skills or theoretical skills?By the i love your style.
Thanks Huzaifa! The biggest difference between an engineer and a technician is that the engineer should know the theory behind why things work the way they do. So theoretical skills are essential. But practical skills are extremely important as well and I think that if you don't develop them yourself, you should at least respect and rely on the practical skills and insights of the technicians you work with.
@@CircuitBread I am becoming an electrical engineer but i love engines of cars.so what field should i choose so that i remain an electrical engineer but i will work on engines.?
Hi Huzaifa - that's a tough question! An electrical engineer would work on the electrical, control, and logic systems of a vehicle but the engine itself... that would be more mechanical engineering and similar fields to that. I personally can't think of any good crossover point for that, but perhaps someone else will think of something.
