Buck Chopper working principle in tamil

Buck Chopper or Step down chopper Working Principle of Operation.
The Buck Converter
The Buck Converter is used in SMPS circuits where the DC output voltage needs to be lower than the DC input voltage. The DC input can be derived from rectified AC or from any DC supply. It is useful where electrical isolation is not needed between the switching circuit and the output, but where the input is from a rectified AC source, isolation between the AC source and the rectifier could be provided by a mains isolating transformer.
The switching transistor between the input and output of the Buck Converter continually switches on and off at high frequency. To maintain a continuous output, the circuit uses the energy stored in the inductor L, during the on periods of the switching transistor, to continue supplying the load during the off periods. The circuit operation depends on what is sometimes also called a Flywheel Circuit. This is because the circuit acts rather like a mechanical flywheel that, given regularly spaced pulses of energy keeps spinning smoothly (outputting energy) at a steady rate.

I got more than 80% in last 3 semesters in electronics paper because of your teaching. THANK YOU SIR........ Keeps rocking

[@iyyanarkathiresan]

Thank you so much sir... Im written the power electronics exam... Today all the inputs from your Videos only...Clear explanations....

[@EEEVIDS]

Keep it up

[@sasikumarkumanan1699]

thank you so much sir very use full for us and easy to understand sir thank you sir

[@mlogaeshwar1247]

Thanks you sir

[@varadharajan3218]

Wonderful explanation Sir. Thanks.

[@DORABIANS]

Why we are using a diode here?
Without diode the same process will continue as like you explain. Is there anything special by using diode

[@rajeswaranraja5811]

As per the reverse power chopper will on and off, reverse current will flow from load to input.
Please give me a clearance if i took it by wrong concept

[@balkrishr3572]

Little close vedio will be more visible.Pl try it sir.Close board view will be more on concentrate the lesson.

[@sebastinraja5149]

Thank you Sir...I have one doubt our aim is step down the output voltage... but u r explained due to the mosfet duty cycle output will come different... please elaborate practically... what is relation between voltage regulator and step down copper... please explain sir I have lot of confusion of both please...

[@rajeswaranraja5811]

I have one doubt sir,
Back emf of inductor direction is opposite to Vin according to lens law, if I am right diode will not become forward bias, because back emf current will flow towards the input.

Sir buck convertor video annupuga sir Monday exam

[@thamaraiselvansampath6099]

tq so much sir

[@jananinamasivayam747]

Super explanation sir

2nd integral la Ton to Toff thana edukanum.. Y should take a Ton to T?

[@elavarasanputhinan772]

நன்றி sir

[@pkmramkumar]

Sir
Inductor value change pannum pothu output current change agum. Enna required current ku etra mari eppudi inductor values select pannanum appudi nu sollunga sir.

[@vigneshkumarbe8258]

How the inductor discharges in the same direction while like in in ON state, sir Kindly clarify it sir
