Good explain

Very good explanation

Very well explained... 👍👍👍

Sr sar bahut achcha Bata rahe hain kya component

Hello, does the frequency change, through feedback, or is the pulse width the one that changes with a fixed frequency, to fix the output voltage, to the required voltage, thank you very much

Very simple concept. Thank You

Good information

Sir app bahut acche se samjhate hai. Sir mujhe sekhna hai.. Mai aap se kaise jankari le sakta hu?

WOOOOOW well explained

Nice video sir

Sir very useful video.

Thank you sir

Superb sir,.. Thank's

Naic all good sir

Series resistor is ntc not ptc. When switch on time ntc is high value capacitor is slowly charging.when heating ntc resistance comes down.the purpose of ntc is to reduce switch on surge current of capacitors. And protect rectifier also .

Hallo apka samjhane ka tarika bahut hi sandar hai. Par mera ek daut hai smps kya hai ye kaise kaam karta bridge, rectifier kya hai,control card kya hai ho sake to 3 card wali machine ka video banye bhale hi 4 ghante ka ho ek ek chij bariki se batye mai aap ka abhari rahunga ...

Thanks again.
