30분만에 끝내는 DC-DC 컨버터 입문_Rohm

"30분만에 끝내는 DC/DC 컨버터 입문"을 주제로 열린 Web 세미나입니다. DC/DC 컨버터의 기초를 약 30분에 걸쳐 알기 쉽게 설명하였습니다. 전원 IC에 대한 공부를 시작하시는 분들에게 도움이 될 수 있는 내용입니다.
・전원 IC의 종류
・LDO의 동작 원리
・DC/DC 컨버터의 동작 원리
・정류 방식에 따른 비교
・상측 스위치의 극성 비교
・DC/DC 컨버터의 출력 설정 전압 범위
PW : 많은 도움되었습니다. 감사합니다

How does Buck Converter work? | DC-DC Converter - 1

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 (Little change) but due to compression (Handbrake + YouTube), The color doesn't change.

sermsak limpadapun : Great explanation, I am glad I studied Mechanical engineering.
Uwe Zimmermann : great animations, correct science and engineering. But please allow your digital narrator to both get some air and give him some emphasis while speaking...
اختراعات الكترونية : ، good
Britantyo Wicaksono : HAHA 200 thousand students will have a midterm test
Ferid Emini : This is the best channel on electronics for sure. So much detail and the explanation is perfect, but I wish to ask you, which software is used?
