    Dear Members,
    I have difficulties in driving IGBTs. How can I manage it.

    Your design is faulty. Redo it.

    Do I detect a hint of bitterness towards engineers from other countries?
    Don't want to help out someone who is possibly replacing you at the moment?

    No bitterness, just no information about what Darab is trying to do.
    If Darab would have giving a small hint at what he is doing, he may get
    a useful answer.

    More like p-o'd by a non-clue question. What kind of difficulties,
    what is he trying to acheive, what does the driver look like?
    Obviously the design is faulty or he wouldn't come asking.

    I wanted to make clear that I wasn't indicating that you shouldn't answer
    questions for people who are possibly replacing you in another country. I
    was thinking about this a while back, and in these newsgroups you pretty
    much always are helping a competitor. But in addition to that, you're
    helping hundreds of other people than the original person who asked the
    question, and you also get to receive help if you need it. It just seemed
    wrong to answer these questions because it was helping outsourced engineers
    get their jobs done, until I examined it this way.

    I did not even notice the name of the OP till it was mentioned.
    YD is correct. We see so many posts here without a clue about how to
    answer the question.

    If anyone has a good FAQ for asking technical questions on a engineering
    /design newsgroups, please re-post it.
     
  8. I don't think the OP is replacing any Americans. It would be quite
    illegal.

    He should have a look at the data from IRF and other IGBT (and driver)
    manufacturers. It's generally similar to driving MOSFETs, but doesn't
    usually have to be as fast, and with a few twists (sometimes you want
    to drive the gate negative, for example). Try Google, too.

    Best regards,

    What kind of difficulties? IGBTs are the easiest
    power elements to drive. Are you doing something
    slightly difficult, like high-side switching into
    inductive loads, etc.? Have you had difficulty
    finding manufacturer's app notes?

    Thanks,

  10. You've got to go easier when letting up on the clutch.

    you forget, american drivers dont know what a clutch is.

    Izzat so? My 280ZX's were five-speed manuals. My personal vehicles
    have *always* been stick-shift until I bought the Frontier PU truck...
    too much clutch-riding in crawling freeway traffic convinced me to go
    automatic.
