This electronics video tutorial provides a basic introduction into clamper circuits which can be used to shift a waveform above or below a certain reference voltage. A clamper circuit is a type of DC restorer circuit. It converts an AC signal into a voltage varying DC signal where the average voltage can increase using a positive clamper circuit or where the average voltage decreases using a negative clamper circuit. A clamper circuit can be made using a capacitor and a diode.

Calls himself the organic chemistry tutor. Has posted more physics and math videos than chemistry videos. Has videos on all topics and domains of science. This guy sure is a legend !

@caiyunwurslin2468 3 года назад

I tried to figure this out by myself ALL day without any luck, my text book only gives very little information. And the circuit looks so simply only with few components, so in some point I thought that I am the stupidest person in the world and get frustrated. You save my LIFE. Thank you !!!!

Great video Sir,I only had to double check whether the voltage fluctuates around the capacitors and max voltage of both the positive and negative clamper circuit...I still love your videos ,Sir .

@km-sc4kz 4 года назад

great video :) I had a doubt: is the time period of the clamped signal the same as the original? Because just looking at the diagram, I'm not sure.

@josephdalal6698 4 года назад

@juansoto6088 4 года назад

Thank youuu. I dont get why the textbook does not go deeper into the time constant and explaining how it affects charging vs discharging (I didnt remember). The book just says the capacitor has a large constant. period. and doesnt give any details on how clamping behaves before steady state. Its so much complex to put everything together without a complete explanation like this.

So many new concepts for me in this video! I learned a lot although I needed to review several times. He did clarify one point from the earlier video that troubled me - so the Rl resistor does assume the voltage of the diode then?

@Enigma758 2 года назад

It seems to me that this circuit would not work well when driving a low impedance stage (e.g. a speaker). I suppose you would have to add buffering if that were the case.

@myjbrz 3 года назад

Hi! There is some points I didn’t understand : 1- at point c which is the debut of the negative cycle the diode is forward biased but it also needs 0.3 V to conduct. Correct me if I’m wrong but when the negative cycle comes the diode anode is at O V but I can’t figure out what’s the potential at the cathode. In other words I would like to know how the diode cathode potential varies during the half negative cycle. 2- since during the half negative cycle the capacitor becomes more and more charged until it reaches Vm how the diode could still conduct if the cathode which is connected to the positive side of capacitor is more positive than the anode knowing that the anode is at 0V ? 3- I always used to draw the potential arrow from the positive side of the component to its negative one. From D to E the diode doesn’t conduct anymore. Then the circuit is just Vin C1 and RL. So for me I would draw the potential arrow from right to left for C1, from top to bottom for RL and from bottom to top for Vin since we are still in the negative cycle which means the bottom is most positive than the top. According to Kirchhoff law I will sum the arrow in the same direction and substract the arrow in opposite direction : Vout + Vin = VC1. This is how I would do. In others words I don’t get how you could say that from D to E Vout is the sum of Vc1 and Vin. So these are the 3 points I didn’t really get from the video. Any help would be appreciated. Thank you !

@ethanhu2831 Год назад

4:05 To clarify, the diode is in parallel with the branch that contains the input signal and the capacitor, and is also in parallel with the load resistor.

@Teyros 4 года назад

How do we determine the polarity of the non-polarized capacitor? I'm not sure when to add the capacitor voltage or subract it from the input when trying to make my waveform?

@km-sc4kz 4 года назад

in the case when diode is forward biased, the capacitor is charged up (because it connects to the voltage source along a low resistance path), you can determine the polarity of the capacitor by looking at the polarity of V input. in the first problem, the diode is forward biased when the top terminal is -ve and bottom terminal is +ve. so the polarity of the capacitor would be -+ from left to right.

@user-dx4xy8of1w 2 года назад

why does the Vm (the voltage across the capacitor) not change in the right-hand side of the negative half circle at the first circle ? (still remains 9.7V)

@Harry001by7 6 месяцев назад

What happens if we introduce a series resistor in the input side and for time varying square wave input signal, how to calculate R and C (if the input signal frequency is around 1MHz how the circuit behaves and what type of diode we have to chose ?).

at 14:14 , can you please explain why we need to use a polarized capacitor

@yvesbouchard5197 3 года назад

Many thanks for the tutorial! Crystal clear, as usual. I guess you meant "will not discharge completely" @7:24.

@naderhazem9928 3 года назад

no he meant charge because the resistance will take all the voltage then the capacitor's voltage will be approxi. zero.

@PunmasterSTP 2 года назад

I think it can get a bit confusing, since discharging a capacitor with a given polarity would have the same direction of current as charging the capacitor with the *opposite* polarity. In either case, in the ideal positive clamper circuit, the capacitor shouldn't discharge appreciably during the positive half-cycle (or, on the very first positive half-cycle, charge the other way). Then during the negative half-cycle, the capacitor would (quickly) charge with the correct polarity.

@MohamedAhmed-nf8qh Год назад

he meant charge because resistance is low, if it was high it wouldn't discharge completely

@SorooshMhs 2 года назад

7:03 how does the + half cycle current flow through C1? Isn’t C1 supposed to accept current from right to left in this arrangement? I mean since it’s it’s an electrolytic capacitor i thought it could only be used in a DC circuit

@eggxecution 4 месяца назад

personal notes, I realized you can kvl capacitors because the supply voltage is AC, capacitor are opened during DC. Since it's AC you can get Vc and VL if it's an inductor. Also, the capacitor charges if current goes from + to -, and when doing kvl, initially, Vc = 0V for positive clamp, so doing kvl would equal load to supply.

@Acesushii. Год назад

what to do when negative clamper has, freq, capacitor, battery and rl value?

@thisz123 3 года назад

At the negative clamper, why put a connection to the earth? If earth is at 0 V potential, than you have a short circuit between power source and ground no (during first wave)?

@PunmasterSTP 2 года назад

That’s a good observation. I think that as long as only one side of the voltage source is at ground, then it isn’t a short circuit. If the more negative side is grounded, then the source would generate a relative positive voltage, and vice versa. From the diagram, the other side of the voltage source has to go through the capacitor and then either the diode or the load resistor to get to ground.

@Yusufksdmr Месяц назад

I want to ask a question What happens on the graph if I change the resistor value?

@usdohs 2 месяца назад

Does a clamping circuit change anything about the shape of the waveform?

@ahmedragab3679 3 года назад

@parasite4076 3 года назад

So what you're saying is that the capacitor charges up in the negative cycle to offer a positive base around which the voltage fluctuates? Thanks for the explanation!

@parasite4076 3 года назад

I see now how that capacitor works, it basically is a line except when the voltage exceeds the positive clamp voltage of the diode in the correct direction. When the voltage is bigger then the stable voltage of the diode on the positive direction, all of the rest of that excess voltage gets dumped into the capacitor, causing it to charge up to the maximum voltage remaining. (i.e the input minus the diode stable voltage)Then when it does, it will remain the same voltage and stay the same(idk why tho). Then what happens is as if the load is connected in series with a DC source, the voltage is the capacitor's. The process starts at the exact moment the peak positive voltage is reached, when the capacitor finished charging. After that it acts like a DC source, and founds the base around which the ac voltage fluctuates.

@PunmasterSTP 2 года назад

I think that is a great way of putting it!

Why don't they just use a biasing voltage,we will instantly get the clamping

@yasinozatl2363 3 года назад

why the beginning of the graph is missing?

@yasinozatl2363 3 года назад

please help

@PunmasterSTP 2 года назад

To which graph are you referring? Could you provide a time stamp?

@rupeshortega9680 3 года назад

Physics tells us that capacitor stores energy through electric field, but electrons cannot pass through dielectric between the plates, but the way he explained, electrons pass through the dielectric but block by the diode in reverse bias, is that so? I hope he would explains it further.

@ohmslaw6856 2 года назад

Current does flow through capacitor

@PunmasterSTP 2 года назад

I may be wrong but I think he was saying that if only a small current goes to the capacitor, then the plates will have very close to the same voltage.

@PunmasterSTP 2 года назад

@@ohmslaw6856 I think it depends how you think about it. Electrons will move onto one plate when other electrons move off of the other, so from the outside, it looks like current is moving “through” the capacitor. But in actuality, no electrons are crossing between the plates (at least unless the capacitor starts breaking down).
