    Testing IGBT module BSM15GD60DLC with a multimeter

    I have IGBT module BSM15GD60DLC. It is installed in 3-phase VSD and I suspect that one output phase is faulty.
    Does anyone has data sheet?
    Is it possible to test this module with multimeter?

    test igbt

    The BSM15GD60 data sheet can be downloaded from:
    http://www.datasheetcatalog.com/data...5GD60DN2.shtml

    As far as in-circuit testing of IGBT is concerned, you will be able to test for shorts and free-wheel diodes ..
    For a proper test you will have to remove module from the circuit and test each IGBT using the following procedure:
    Testing IGBT
    Basic testing IGBTs (Insulated Gate Bipolar Transistors) should be similar to an enhancement mode N-channel MOSFET except that the threshold voltage may be larger than a typical MOSFET (e.g., 8 V instead of 4 V).

    Check for shorts with an ohmmeter.
    Put a current limited supply across C-E with an ammeter in series.
    Apply at least 10 V G-E. The transistor should turn on.
    Ground the gate. The transistor should turn off.
