  • Power Supply Comparisons
    Linear Power Supply vs. Switching Power Supply vs. Unregulated Power Supply
  • The Ever Shrinking Power Supply
    Changes in power supply design are rarely revolutionary. Rather, they are evolutionary and dependent upon a host of component and manufacturing technologies that, for the most part, develop at a modest pace. Moore's law simply doesn't apply to power supply design; if it did, a 200 W switcher
  • Redundant Power Supply Concepts
    are implementing redundant power supply concepts combined with redundancy modules.
  • Tranformerless Power Supply TechBrief
    In most non-battery applications, the power to the microcontroller is normally supplied using a wall mounted transformer, which is then rectified, filtered and regulated. In most applications, this method of generating the regulated voltage is cost effective and can be justified. However
  • Supplying an AC/DC Power Supply
    A frequently asked question concerns the suitability of using an AC/DC power supply with a DC source. There are two parts to the answer, one concerning the ability of the converter to run without issue and the other concerning the safety aspects. Most universal input AC/DC supplies (designed
  • Designing in the power supply that you need!
    Global applications require a power supply that can deal with not only a universal AC input, typically 90-264 Vac, but also meet the customerâ s lifetime expectations across all operating conditions. It is quite common that the power supply manufacturer will specify a derating factor in the 90-115
  • Power supply de-rating in practice
    With mounting market pressure on power supply size, power density and cost there are an increasing number of AC-DC power supplies released which rely on de-rating specifications to improve their headline power ratings.
  • How to Diagnose Power Supply Problems
    Before leaving the plant, power supplies are always subject to performance testing. These tests include line regulation at full load and operating temperature. The problem with these ideal testing conditions is that there's no guarantee that the operating conditions of a power supply
