    Before feed to transformer can tell me the value of ac voltage which is further stepdown to 5v aprox.
    (? v / 5v ) transformer rating.
    Is it 220v or any other.
    Please tell me.

    Sir I built 5 V 3 amp mobile phone charger but all phones are taking maximum 700ml amp only what is the reason?

    brother the white part of the diode emmites positive charge current not the negative charge current optocoupler is not a microcontrooler it is connecting device through led light inside of it

    Bhai rectifier n capacitor ke baad to ac dc ho gayi fir transformer ka kya use. Pehle transformer hona chayie tha n then rectifier!

    you r telling wrong , you telling as cathode as anode and anode as cathode….

    At Last stage I.e., before going to input there is only one diode that means half wave rectifier!!!
    Why????? There should be full wave rectifier isn't that???

    Bro you have used an integrator circuit in the secondary part of transformer coil. Can you explain, how you have converted AC into DC using an integrator ?

    sir can you tell me how mosfet is converting dc into ac with transformer series connection pls clear the concept for me
    thank you waiting for your reply asap

    Has the potential to be interesting but you're very hard to understand

    sir how optocoupler is used in here and how mosfet gets triggered??

    in ckt digram we can't connect the transformer at input side .due to high voltage diode will be burn out

    are you gargling marble or something? i can't hardly catch up your explanation and some key function were not explained…

    Bhai mosfet doesn't convert dc to high frequency AC , it converts that dc to high frequency pulsating dc.. which acts like ac, as voltage is changing from 0 to particular value … After rectification voltage never goes in negative side so there is no ac going in transformer , its pulsating dc.

    what if remove the rectifiers diodes and replace them with a short circuit?
    will I get 5V ac ?
