    IGBT equivalent load

    Hi,
    I am using FF450R12KT4 IGBT module for my project 3phase inverter.
    I want to test power supply for IGBT gate driver IC at -20degC with full load ( i.e. all 6 PWM channels are ON).
    But in order to test it at full load I need to connect 3 IGBT modules ( each contains high side and low side IGBT) which I do not have,
    so can I connect 28nF capacitor as a load to gate driver IC (as IGBT input capacitance is 28nF) ? ( I am not connecting any motor to IGBT, I just want to test power supply)
    Or I need to consider gate charge for output load capacitance(dummy load in place of IGBT) measurement ?

    Regards,
    Jitendra

    Hi Jitendra,
    welcome to the Infineon gate driver IC forum.
    can i first ask you which gate driver have you selected for your application?
    Best regards,
    Emanuel

    Hi Jitendra,
    That specific product is not an Infineon gate driver.
    I would suggest to get in touch with the manufacturer of the gate driver you are using as they should be the best at supporting their product .
    Unfortunately, as this is the Infineon gate driver forum, we are experts in the Infineon gate driver protofolio.
    Best regards,
    Emanuel
