How a Switching Power Supply Works and How to Make One

Circuit Link:

In today's video I'll be showing you how to make a Switching Power Supply with a detailed description about the working of a practical Circuit. It's a simple yet very capable Self-Oscillating Flyback Switch Mode Power Supply which has a Regulated output of 12Volts and a Current capacity of up to 10Amps.

Nice video am from Nigeria good morning and good work u did I love it

I know many people have been wondering if the circuit works or not. The simple answer is that in its current form "NO" or maybe if you buy a damn powerful mosfet with literal cooling and also way too big transformer for the purpose. But the circuit can work with various modifications and indeed with an EI33 Core if it is balanced at both ends. I have built a working 16V flyback converter inspired by this circuit. If there is anyone who wants to build a 16V AC/DC converter, I can recommend the rebuilt version so you don't have to buy 10 pcs. mosfet which you will otherwise burn.

Thank you brother foe this educative video.

I wish you could dub the audio again, the audio quality is very poor, your viewers cannot understand what you're talking.

[johnconrad]

Good Video explaining everything. Design can be improved. You have R2 = 1K gate drive resistor (make it 10 Ohms) Gate drive is very slow so slow switching wave forms so FET gets HOT so you need to use a HUGE MOSFET IRFP460. The primary current is 0.7/0.22 = 3.2 Amps pk. and the transistor is capable of 20 Amps. Perhaps other improvements but I leave that to you.

What changes need for out put 48v 5Amp.

I know you had the best of intentions but without good audio quality, this is all for nothing. If you could also speak a bit slower it would be very helpful. This was very difficult to comprehend.

Хорошая схема, сохраню ! Боагодарность

[RanaRao_Chandrachur]

can u please tell me how to calculate the switching frequency and the duty cycle from the feedback R2 and C6??

[jairoortiz]

nosotros los hispanoas quedamos gringos amigo, gracias x el video

[fazelesami]

hi . how to calculate frequency of this circuit?thanks

[josepeixoto]

You have 12.7V and a 12V zener; the Vf of the ired led inside the opto is 1.2v to 1.4v (?) does it work like that, i guess not

[prasadghadigaonkar]

How much frequency for operate this device

[kumawatajaykumarsureshbhai]

hallo brother how the MOSFET get the switching frequency can you give me the answer plase

[m.y]

Can you please talk about feasibilty of the circuits you analyzing. Because most of them are not practical and actually not working.

[omera-i]

hi sir
it's a good work
I want the exact components of this circuit and the process explained by text

[amirshehzad]

Can anyone tell me the range of frequency to drive the MOSFET in the supply

[RafaelBeltran-ol]

The music needs to go away...i don't understand why there is music.. And the icon at the bottom flashing. Is another distraction... Can't hear your explanation...

[dattran]

Could you share me the transferfunction of this circuit

[rra]

what changes need to be done if we want an output of 36V, 5A.
Plz reply ElectoBUFF
