    1ED020I12-B2 driving 3 IGBT FF200R12KT4

    Hello to all!

    I would like to know if the driver 1ED020I12-B2 can handle 3 IGBT Infineon FF200R12KT4 ( 3 IGBT for each channel ).

    It will be used in a full bridge inverter, input 125 Vdc, output 220 Vac with isolated transformer.

    Is just put separated gate resistor?

    Sincerelly;

    Marcelo

    Hi Marcelo,

    The 1ED020I12-B2 has max driving current of 2 A and it cannot drive 3 FF200R12KT4 IGBTs on its own. It will need external booster stage as shown in page 11 here https://www.infineon.com/dgdl/Infine...24b57c56d76a7b

    You can also look at 2ED300C17-S high current driver board.

    Thanks and regards,

    Srivatsa

    Thanks for the anwer Srivatsa!

    In the app note, they use two complementary pairs of transistors. What is the reason?

    If i select a unique pair of transistor with the current capacity it should be used?

    Hi Marcel,

    The complementary pair easily provides fast turn on and turn off characteristics.

    Pls look here https://www.infineon.com/dgdl/Infine...46ffb0461d3894

    This application note gives you the information needed to design the external booster stage.

    Thanks and regards,

    Srivatsa
