In this video we will explore the design and working of a closed-loop buck converter.
From its basic circuit to feedback driven circuit, we will explore it completely.
Correction: 6:05 - The duty cycle of PWM "increases".😅
Chapters:
00:00 - Introduction
00:17 - PWM
01:12 - Adding Inductor
02:30 - Frequency Increase
02:45 - Adding Capacitor
03:52 - Basic Buck Converter
04:13 - Closed Loop Buck Converter Circuit
04:20 - Operational Amplifier or Op-Amp
04:54 - Differential Op-Amp
05:30 - PWM Generator
06:08 - MOSFET
07:00 - Supply and Reference Voltages
07:25 - Normal Load (Output Voltage High)
07:37 - Double Load (Output Voltage High)
08:05 - Change Output Voltage
08:23 - Important Points
08:28 - 1) Voltage Divider
09:00 - 1.5) Load Change
09:21 - 2) PWM Generator (Reversed Comparator Inputs)
09:40 - Outro
The feedback does changes at 07:37 (Small change) but due to compression (Video + KZfaq), The color doesn't change.😅

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.

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

Triangle wave as a duty cycle template with the comparator is freaking genius.. never crossed my mind before.

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.

@@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.
