    It's also important to be able to control the current.

    Hi. If possible, in the same circuit, in addition to the variable voltage, it also controlled the current was excellent.

    • @ELECTROBUFF

      Yes. Variable current can be easily achieved with the help of an Operational Amplifier feedback to either one of the error amplifiers or the dead time control pin input

      If i change R6 to a 10k pot, Will that change the current?

    I like the design, straight forward. Neat little IC, I need to check it out. I set reminder!

    Hello there
    nice project well explained
    one question
    how about input voltage is 30 volts
    what the transformer primary windings will be?
    Thanks in advance

    Any chance you could point me to a resource that will help with incorporating constant current control into this circuit??
    Thanks for the upload!

    I've assembled this, exactly as you mentioned, but not working...E. Output pin 9, 10 is zero volt, then how a N channel mosfet will work, after disconnecting 557 base connection the results are same, 0 output voltage, it seems the diagram is wrongly designed, even I've tried the same with replacing 4nos of ICs, but no variation....
    Plz suggests what to do ( for trial I've changed the connection of E1 and E2 with groud and added 2 nos 1k5 resistor to 11 and 8 pin, now it's giving output voltage )

    Hi friend! May I input 20~27V to 24V output ? Ill need 5A output (120W) but My load will charge instantly... I need this circuit doesnt get under voltage... Did you did this kind of test?
    Congratulations for your video! Ill wiil feedback you if it works as expected!

    hi sir...sir i made this circuit but when i took ( 12volt 2amper on output) that( took me 12volt 8amper on input)...i don't know..but i need to know of your opinion my circuit work correctly??? because i expected when i took 12volt 2amper on output we must spen 12volt 2amper on inpout...please lead me

    Hello. Have you built and tested this circuit in practice? Do you have any measurements results?

    • @AmiltonJr
      @AmiltonJr 2 ปีที่แล้ว

      I decided to test in real circuit. It works perfect. I've tested it so far with 1.5A loads.
      I intend to increase the power by modifying the drivers and mosfets.

    Can you provide a diagram for 12 v dc to +35/-35 v dc dual supply for amplifier?

    • @ELECTROBUFF
      @ELECTROBUFF  4 ปีที่แล้ว +1

      You can use this, just modify the secondary turns for a lower voltage

    Why in output side we used transformer

    • @ELECTROBUFF

      The Transformer allows for more stable buck and boost with better efficiency and power capacity.

      Yeah, with much better feedback and power capacity than a classical dc dc buck boost Converter
