    Inductor as Energy Storage/Transfer Element

    For some people the purpose of inductor is ... to generate sparks. I was not giving direct instructions "how to". I just sketch the principle of using the inductor for storage and transfer of energy. I was thinking that somebody else will continue to form the complete picture, but... There such...

    Which CAD tool is better: Protel 2004 or OrCAD 9.2?

    Re: protel or orcad I am an O*CAD fan. I have also many friends working with P*otel and have a lot off problems with it. It has too many bugs it is resources hungry and crashes as a rule. O*CAD is much simplier, I have learned the basics for a couple of days. You don't have 3D but you can do...

    Inductor as Energy Storage/Transfer Element

    Hi, if you apply a voltage on the leads of an inductor. The current starts to flow through it. The current will ramp linearly. It depends from the period of time in wich the voltage is applied to the inductor leads, to how much the current peak value will reach. The equation is: U = - L×(dI/dt)...

    Formula for calculating POT core parameters

    effective core parameters Hello, I need the formulae for computing the parameters of a POT core, such as "effective magnetic path legth, le" and "effective cross sectional area, Ae". I know I have to find C1 = Σ(l/A) and C2 = Σ(l/A²). And then to calculate le = C1²/C2, Ae = C1/C2. But I need...
