  2. Boost converter - Wikipedia

    en.wikipedia.org/wiki/Boost_converter

    Low-cost converter modules: two buck and one boost. Boost converter from a TI calculator, generating 9 V from 2.4 V provided by two AA rechargeable cells.. A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output ().

  3. Buck converter - Wikipedia

    en.wikipedia.org/wiki/Buck_converter

    A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...

  4. Decade (log scale) - Wikipedia

    en.wikipedia.org/wiki/Decade_(log_scale)

    To find out the size of a step for a certain number of frequencies per decade, raise 10 to the power of the inverse of the number of steps: What is the step size for 30 steps per decade? 10 1 / 30 = 1.079775 {\displaystyle 10^{1/30}=1.079775} – or each step is 7.9775% larger than the last.

    en.wikipedia.org/wiki/Stepped_reckoner

    The stepped reckoner or Leibniz calculator was a mechanical calculator invented by the German mathematician Gottfried Wilhelm Leibniz (started in 1673, when he presented a wooden model to the Royal Society of London [2] and completed in 1694). [1]

  6. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC).

  7. Source transformation - Wikipedia

    en.wikipedia.org/wiki/Source_transformation

    Source transformations are easy to compute using Ohm's law.If there is a voltage source in series with an impedance, it is possible to find the value of the equivalent current source in parallel with the impedance by dividing the value of the voltage source by the value of the impedance.

    where is a reconstruction offset value in the range of 0 to 1 as a fraction of the step size. Ordinarily, 0 ≤ r k ≤ 1 2 {\displaystyle 0\leq r_{k}\leq {\tfrac {1}{2}}} when quantizing input data with a typical probability density function (PDF) that is symmetric around zero and reaches its peak value at zero (such as a Gaussian , Laplacian ...
