As an example, assume Rt is 300 ohms. Calculate the total inductance of the circuit, or Lt. Lt depends on the number of inductors and how they are connected. If only one inductor exist, Lt is the value of that inductor. If several inductors exist, determine if they are connected in se...
In addition to these electrically neutral molecules floating about are molecules that carry a net positive or negative electrostatic charge. These are calledions, and it can be handy to have an ion tester on hand to measure negative ions in particular; one everyday example is a household smoke ...

of the inductor. The permeability of the core is directly proportional to the saturation level, hence the inductance also changes. This change in inductor value is analyzed by the flux gate sensor to sense the current. If the current is high, the inductance become lower, if the current ...
To understand the process, let's first look at what inductance is. The illustration on this page is helpful. Here you see a battery, a light bulb, a coil of wire around a piece of iron (yellow), and a switch. The coil of w...
I'm designing an input filter for a power converter and the output impedance of the filter needs to stay comfortably under the input impedance of the converter, which looks like a 15 uH inductance at its operating point. Staying under 15 uH is a squeeze, but this one seems to be a good...

Stackup Design: Optimize layer stackup to ensure ground and power planes are strategically placed to minimize impedance. Via Impedance Just like a PCB substrate will have some parasitics between neighboring conductive elements, so willvias in a multilayer board. The inductance of a via is ...
(ISAT) is a measure of electrical current when the inductance drops to 70% of its value. ISATis determined by the inductor’s core size for a given core material and construction. As opposed to using separate DC-DC converters, the approach of using a single inductor in...
The large dI/dt’s passing through the inductor in the LC filter result in large magnetic fields that are generated in the vicinity of the SMPS. Any loop with a low-inductance path will have magnetically induced currents that generate voltages which we measure with the scope. ...
