  • Optimize Power Factor Correction Inductors
    . Inductors called chokes are used as parts of filters in power supplies, or to block AC signals from passing through a circuit. Almost any style of power inductor can be used for Power Factor Correction, but for this analysis, toroidal inductors are used. Toroidal inductors offer higher performance than
  • How to Reduce Size and Increase Performance in AC-DC Power Supply Design
    Improvements in AC/DC power supply design are evolutionary, rather than revolutionary. It's easy to settle for tried-and-tested approaches because no one new design technique is likely to yield great benefits. The design challenge is to establish what small enhancements can be made in various parts

  • Shrinking to the Challenge - How to design a Smaller, More Efficient AC-DC Power Supply
    . Furthermore, these power supplies must fit the standard formats that are already in use to avoid system re-design costs. In the case of AC/DC power units, it is not dramatic technology breakthroughs that drive the trend, it is good engineering and the inventiveness to combine the best of a whole range
