  • Introduction to Power Inductors
    A power inductor, also called an inductor coil and choke inductor, is a passive electronic component consisting of wire round around a core of ferrite that includes an air gap that is used to clean up the output from high frequency switch power supplies. Selecting an inductor is more complicated
  • Power Supplies
    e-Vap® CVS Series Power Supplies are constructed using state-ofthe- art solid state high frequency switching technology. They are offered in three standard models rated for 6kW, 10kW and 15kW. CVS series power supplies are for use with the horizontal and vertical flange mounted systems detailed
  • Designing Power Supplies for Global Applications (.pdf)
    Switched-mode power supplies (SMPS) provide an ideal solution for meeting global power requirements. SMPS designs can automatically adjust for variations in input voltage by changing the pulse width to maintain a constant output voltage. A straightforward design approach using two power
  • How to Achieve a Stable Power Supply through Digital Control
    , faster transient response and high switching frequencies, have been around for decades. But throughout the entire history of power system design there has been one requirement that has been constant: the need for a stable power supply. Check out this article from Intersil to learn how to design
  • Rescue Microvolts from Volts of Noise
    High-frequency common-mode noise may be introduced into a data-acquisition system from a variety of sources, including fluorescent lights and switching power supplies. The excellent high-frequency common-mode rejection of Ectron's Model 778 amplifier enables it to separate much of this noise from
  • Keep Hybrid Powertrain Drives Noise-Free by Rejecting dV/dt Noise with Isolated-Gate Drivers
    High common-mode noise is a significant problem that automotive system designers must overcome when designing a practical and reliable powertrain drive system. Common-mode noise (also known as dV/dt noise) is generated naturally within a system when there is high-frequency switching
  • A Simple Circuit for Driving Microcontroller Friendly PWM Generators
    for designing a switching power supply as a peripheral to a microcontroller: a set/reset flip-flop, a high-speed voltage comparator and an op amp to implement the error amplifier. The microcontroller controls the MCP1630 through its clock input. The frequency of the clock determines the pulse
  • Application Note: AAT3190 Positive/Negative Bias Supply for CCD Camera Sensors
    and output power supply ripple for the best circuit performance. CCD camera sensor applications demand several different power supply requirements: • Need to create high voltage positive and negative bias supplies from a single cell lithium-ion/polymer battery source. A single cell lithium-ion/polymer
