  1. Calculation of snubber components and driver gate resistors

    Dear members I am presenting an Two articles regarding the calculation of snubber components and gate drive resistors.
    It often comes the need to determine the snubber components in a half or full bridge smps. The snubber described here is intended to be put across the primary winding of a switching transformer, however if ringing is present due to factors like leakage inductance present in switching transformers we need to suppress them. In the previous article presented the text moved ...

  2. How to calculate snubber components for half and full bridge smps

    HOW TO CALCULATE THE SNUBBER COMPONENTS FOR SMPS

    1) Put your oscilloscope probe across the LOW SIDE fet (Drain source) or BJT (collector emitter) be sure to put the ground lead
    to the negative side of the bulk caps (source of mosfet) (Emmiter of BJT).
    2) Isolate your power supply if it is an off line one to be tested with an isolating transformer otherwise there is a good chance of
    burning your oscilloscope and your smps.
    3) Depending ...

  4. Transformer winding practices for smps

    Many of us DIYers need to wind their own ferrite core transformers and when the need comes we all try to put our hands in it. Some of these cores will be just carrying low voltages and the insulation between windings will not have to be so important due to the low voltages involved and does not have to be so specific.

    However problems will arise when we deal with off line SMPS and care must be taken into account when dealing with insulation between windings and mandatory ...
