Testing High Frequency Inverter Board with Short Circuit Protection

High frequency inverter board came in yesterday. The major adjustment on this is the short circuit protection using shunt current sensing resistor and optocoupler, also proper filtering of the high voltage was done also, I am going to carry out some test on the device this weekend

    Very neat. What is the purpose of some of the really large traces and/or fill zones? Also, did you consider filling the whole unused area with a ground plane? It may work fine, but that is supposed to be good practice.

  2. melta101#0000

    most probably it’s passing high current

  3. afuevu_#0000

    This one currently has high current passing through it

  4. afuevu_#0000

    Yeah you are right

  5. afuevu_#0000

    I did fill the unused area with ground plane, there are actually two gnds on the bord

  6. afuevu_#0000

    For now I’m just testing the circuitry connected to the first gnd, I’ll drop more updates

  7. jeremycook#0000

    Sounds good on both counts. How is it working out?
