    Hello every one
    I was looking for converting 600v dc > 28 v dc & 60 Amp
    till i found a circuit making this

    [​IMG]

    but the problem is that the switches have 3 pins each one but the connected is only 2 of them
    So it made a problem in simulation

    so what is the problem

    i am waiting for your answers
    thanks

    hi,
    Your circuit diagram shows only the power out stage, it requires a driver stage for the FET's gates.

    hi,
    If you Google for half bridge dc dc converter driver you will see ideas for the driver stage thats required for your posted circuit,

    Not a beginner project. You should start with something much lower than 600V.

    For a beginner who only connects two FET pins!

    Your understatement almost made me snort my milk. :D
