Good as this video is, it is yet another example of why it is important to have a human do the narration rather than a text-to-voice system. This video would likely have been better with a real voice.
Good basic explanation. An Analog voltage reduction uses resistance to drop the voltage,,which generates a lot of heat. A Buck convertor storing the charge in magnetic Flux is far more efficient.
I was using artificial voices, but have come to the same conclusion. However, the more recent engines are much better, and a little work at spacing correctly and Interpunktion are essential. Just writing information and read it from a sheet is rarely the information people listen to.
There is so much understandable information here that my brain can’t absorb it all in one view! Great explanation and video!! Must watch it multiple times.
Typically a sawtooth wave is used, but either way that's how it has been done for decades. Linearity of the triangle or sawtooth is not critical since the feedback circuit cancels any effects of non-linearity. If you are making something like a signal generator then you do want very good linearity.
Because youtube is so awesome, they cannot show the dislike counter. For those wondering if this video is good information, this video is UNMATCHED. Everything in this video is true to an Engineering A+. The fact that PWM is discussed and how it is generated further shows a true engineer wrote this video. Excellent information. Thank you for your wisdom!
Yo that's a solid ass video my man. Very very good. Step by step explanation. I never thought of inductors as becoming a battery due to their stored up energy in the magnetic field, and now that i think about it, it feels sooo obvious. Thank you very much
I recommend 0.75 x speed, if you're using keyboard, click the video, hold shift and press < once if you're using phone, press that three dots on the top right, and select playback speed, set to 0.75 x
@@ExplorerStuff could you please tell us which software do you use for making animation? if it's possible can you please make the tutorial on your animation?
150kHz is LM259x but the triangle wave of the modulator is only used on LM2574/5/6 which is 52kHz. Next video you need to deal with how the LC filter introduces a double pole and gives a 180degree phase shift.
Dear sir its my request to u please cover the whole electronics concepts in 3d animation .. so that it ll be helpful for me to design a circuit & understand ...
amazing tutorial as ever, 1 more quick tip for you, new challenge emerged on RUclips *Transformerless Power Supply* so 220AC mains dropped with the help of X-rated capacitor (down to 12 volts dc) placed before bridge rectifier, I searched a bit, yes There are few videos about it,(many of them in Hindu language) but almost no any proper video tutorial about it for English speaking audiences, it's good time for you to smash that challenge (make a detailed video about it/especially how to calculate capacitor rates for different low voltages) and become number 1 👍👍👍👍
@@ExplorerStuff not only I think so, I'm pretty sure that you can make it better than many many others ☝, I may have described it not much accurate, it's called x-rated capacitor, I'll put a link here for you to see what I'm talking about
This is a dangerous circuit. 1) No isolation from mains. (Most Important) 2) The Zener is active always (100%) and for large currents. 3) If there was no Zener diode, This would increase the output voltage to the input. 240V. 4) By 2,3 The Zener takes too much current through itself. It will burn in seconds or minutes. 5) If the neutral wire gets grounded (By Mistake or poor wiring), then the output of rectifier is double the input voltage (+240V & - 240V = 480V).
Wow that is amazing I will show it to my students. You could make a boost converter also, then an isolated topology would be nice :). Keep up the good work!
@@ExplorerStuff Many thanks, I was looking for a buck converter and took advice from an Electrical Engineer that said he would never use a cheap converter because it can damage the much more expensive battery, BMS and load, but didn't explain why. So I went to Amazon and found lots of cheap $1 bucks that are tiny and one large for $20, I was confused by the large number of components on the more expensive one when compared to the cheap version as they both claim to do the same thing, now I understand why.
It would be extremely unusual to configure the voltage error amplifier for unity gain at DC. Typically, though not always, the EA is run open-loop at DC and the frequency compensation components assure proper 0 dB gain crossover at a frequency that maintains adequate phase margin for stability.
3:58 ERROR: Please note that the output voltage is independent of the load. The output voltage only depends on the input voltage and duty cycle. Changing the load could change the output current and hence output power dissipated. But you will still have a fixed average output voltage.
I was thinking the same thing when I saw it. The PWM wouldn't need to change to keep up with the change in load (assuming all the components can handle the higher current).
that's odd I'm having a laboratory work on Simetrix regarding buck converters and my groupmate has the average output voltage and the peak to peak ripple of the output voltage increasing as the load increases
Excellent video, I have a question, you have technical information if there is any to design a DC DC converter with positive variable input and that has a DUAL symmetrical output (high power approx. 2A) of +15 VDC and -15 VDC. Know of some base design with the theoretical source and some switching regulator.
So can we make a closed loop buck converter using ne555 as square wave generator and lm358 as a comparator🤔. if yes , then please make a video on it. This would be really helpful.
A square wave generator instead of the triangle wave generator. -> It won't work, because we need a linearly varying wave (triangle, saw, ramp, etc.). A square wave in the comparator will result in the same square wave at the output. In a triangle wave, the intersection point between the wave and the constant voltage (by error amplifier) creates the PWM. As the constant voltage moves, the intersection point also moves. But in the case of a square wave, the intersection point will always be on the same vertical line. Hence, its duty cycle will not change. LM358 -> as we need two op-amp (1 for error amplifier, 1 for comparator), this will be great.
@@ExplorerStuff thanks for replying . I am newbie in electronics and that's a lot of knowledge for me. And interested in making a buck converter without using lm2596. So it would be great if u make video on it. Thank U
Hello, first of all good job for explaining how it works. Second I tried to replicate the circuit in a ltspice simulator and I was not able to achieve a good result. Most probably I missed something out while trying to replicate the circuit. My voltage drop when I add a low resistive load and the variable resistor doesn't have any effect on the output so obviously something is not right in my circuit. I noticed in your video that at min 04:00 power supply is connected to the drain pin of the mosfet while at 07:00 power is on the source pin. Could you please share with us a clear circuit diagram so we can try to replicate it? I can send you the diagram of my circuit if you want to see it. Thanks and looking forward to your response!

Just replace the feedback circuit with Arduino,
i thought i'm the only one who keep repeating this.. but I agree this is great!!
Triangle wave as a duty cycle template with the comparator is freaking genius.. never crossed my mind before.

The explaination of Inductor and Capacitor in this video is sarcastically more understandable than those dedicated videos out there.
Nice to see that the circuit is properly grounded !! :)
Explorer: is a best electronic channel ever as I found online till now. keep it up you are doing tremendous job.

PWM is so useful in current regulation in everyday devices. Cheap, reliable components for speed control, etc are such a convenience
This is the best channel on electronics for sure. So much detail and The explanation is perfect!
True bro!
Yep, I agree with you
Too bad it's a busted ass representation and explanation of what's going on.

It has a maximum power rating tho. So, when it draws more current, the voltage will drop.
