    Hi.

    Im using FUJI IGBT (1MBI300N-120 ) in my test project.
    To make the project simpler i was planning to implement the commercial IGBT driver.

    I found some of the drivers on farnell website but i dont know how to connect the driver.
    There are bunch of inputs for which i have no clue how to use it.

    Can someone help ?

    You have no clue as to use the "bunches of inputs" and we have no clue as to which of the "bunches" of drivers your using. Sounds like a fair trade. :)

    :rolleyes:
    Voltage should be from 10-20V and current can be up to 10A (in some middle value). This is the link http://uk.farnell.com/igbt-gate-drivers.

    There are few models but i dont know which one should i use.
    Tell me what kind of data do you need so i can write it down.

    Transformer values ?
    Input / output voltages of circuit ?

    All of that plus a schematic of your circuit. Are you using the IGBT as a high side or low side switch? Also how fast is the circuit switching?

    We are using low side switch and the circuit is not fast at all. Frequency of gate impulses are 200Hz. It is important to know some characteristics of this specific IGBT like gate capacity or gate charge for choosing the appropriate driver.

    Basic schematics ( without IGBT and transformer ):

    Transformer:
    Input: 72V
    Output: 450V
    Power ( at 200hz ): 8KW

    Circuit:
    Input: 72V
