Electrical ratings are interdependent. The current through a component depends on the applied voltage (waveform and duty cycle) and the component impedance. The impedance of a component depends on the ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

[Kalle] tipped us about a quick project he made over a couple of evenings: an inductor saturation current tester. All the components used for it were salvaged from a beefy telecom power supply, which ...

This video/article is part of Dostal's Designs series in Ideas for Design and the TechXchange: Power Supply Design. You can also post a question. Members can download ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Specify current ripple ratio to optimize a power supply , relying on extrapolation rather than intuition to choose the right off-the-shelf inductor for your application. An inductor is designed for ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...
