Buck converter working explanation dhaaraalama irukku, but no output utility Videos... For example, output frequency optimization for pre amp modules like BT module. Humming noises.
+LIJU JOHN Regulator: For example, if the input is 12V and you are using 7805 regulator, it will give 5v but the remaining 7v is simply wasted here. The reason for the regulator is heating also the same. it is almost grounding 7v. Buck converter: When you reduce the 12 v into 5v using a buck converter the power is almost maintained here. It is not wasting the power as in the regulator. So regulator is suitable when you have unlimited power. Buck converter is suitable when you have limited power(eg: solar, battery)
@@ElectronicsForUs Nice i have another one doubt.....12 v 7Ah battery charge panne input voltage எவ்வளவு கொடுக்கனும்......19 v dc voltage input ah கொடுக்கலாமா??????
@@prakashtamilan9864 For a rechargable battery the charging voltage should be given on the body of the battery. Typically the charging voltage will be 13 to 13.5 for 12v battery.
very very useful videos ,simple and good teaching...
Rombe nandri 🥺🙏🏾🙏🏾🙏🏾
Good explanation with example
Very usefull you are teaching method thanks sir
Good explanations. 👍👍
waiting for the detailed explanation!!!!!!!!!
Can we change la power of the load?
well explained!!! Keep up your good work!!
Good work bro
I have the doubt how the switch is controlled
What is switching frequency

Very good sir....i want more doubt about controller sir....plz help

Ok. Will put a separate video.
Thanks🙂
@@ElectronicsForUs sir explain derivations for buck ,boost and buck boost regulators
Hi Rajeshwari,
I will put a video for calculation regarding power inductor , snubber, frequency/Duty cycle.
But in later part.
@@ElectronicsForUs OK sir tq
Explain buck & boost converter formula
Ok
What's the difference between regulators and converters Sir

Modified sepic converter
Sepic converter sollunga bro
Ok
Stepdown and stepup choppers explain
+Maria V
Ok
Bro explain CCM DCM and PWM mode in Buck
Ok
Pls give the Value of the inductor, capacitor and MOSFET details
There is a calculation to find the values depends on frequency, input current, output current, expected voltage, etc.,,
We can't tell directly.
If you go for a buck converter then you have to be ready to spend ten times of what you have paid for a regulator.

@@ElectronicsForUs In case if we provide 19v dc power supply to that battery what will happen????
Not clear explanation
Sir do u have any circuit for single key on off circuit for 9 volt DC or 5 volt DC instrument. Please give me your mail id sir
