  • Intelligent Thermal Management Using Brushless DC Fans
    The brushless DC fan (BDC Fan) has become the air mover of choice in computing equipment, office automation products, home entertainment systems, and the like. Unlike conventional DC fans, the BDC fan is mechanically robust because it contains no rotating commutator/brush assembly to shed dust
  • Inverters- Powering Switched Mode Power Supplies
    Power supplies are used to convert AC voltages like 120 VAC to various DC voltages like 3.3 V, 5 V, 12 V, 24 V, 48 V etc. Majority of modern day electronic devices use embedded general purpose Switch Mode type of Power Supplies (SMPS) to drive the electronic circuitry. General purpose Switch Mode
  • Medical Device Link .
    , and 16-A testing capability. Multiple functionality is also one of the features of the Guardian 6100, developed by , which performs five electrical safety tests. It carries out ac hipot tests from 50 to 5000 V and dc hipot tests from 50 to 6000 V. Current-trip levels for the ac and dc hipot testing
  • Phase Control Using Thyristors (.pdf)
    . The thyristor is held in the off condition - that is, all current flow in the circuit is blocked by the thyristor except a minute leakage current. Then the thyristor is triggered into an "on" condition by the control circuitry. For full-wave AC control, a single triac or two SCRs connected in inverse
  • The lowdown on lowdropout regulators
    . This low dc voltage is the primary power, or system rail, for the embedded circuitry. The most common system rail values are 3.3 and 5 Vdc. Embedded microcontrollers, though, are powered by voltages ranging from 1.8 to 5 Vdc. The LDO regulator synthesizes the lower voltages from the system rail
  • Single electron toggles transistor on and off
    A new type of transistor takes only one electron to switch between on and off, a breakthrough that could lead to lowpower chips with higher computing densities. A micrograph of the single-electron transistor (SET) superimposed on experimental circuitry shows the source, , along with the applied ac
  • High-five to high-side current sensing
    through the meter. The technique was called high-side current sensing. However, high-side shunts require isolation in modern electronic control systems because of their direct connection to the high-side voltage rail. Current transformers perform this service in ac power systems. But the size and cost
  • Computer Power User Article - The Big Overload
    you an electrical engineer, but it'll help you make better decisions regarding your computer's vital components. Your PSU starts its job by pulling in electrical power from a wall outlet. This power comes in AC form, so it must be converted into the DC voltages that are used by computer electronics
