Basically a bank of capacitors is charged to a high voltage and/or high amperage. But judging from THIS website it is probably a ferrous alloy powder E core.Ī coilgun is the not so correct name for an electromagnetic projectile accelerator. And I have absolutely no idea what it’s made of. It’s 1.5 inches long, 2 inches tall, and half an inch thick. I’m not sure what the original frequency of the power supply is because I don’t own an oscilloscope.The core is shaped kind of like El, kinda hard to illustrate. I haven’t decided on a final frequency yet, but it would probably be something around 1.5KHz. If not then I guess I have to make an air core coil.įirst off this inductor is for a dc/dc boost converter.

Can anyone tell me how to find the permeability of any given material, or if I could but a core with a known permeability. I can’t just calculate the inductance as if it was an air core coil because the final data would be incorrect. I checked the markings on the outside but came up empty. I’m using the core of a gutted transformer from an ATX power supply. īut the only problem I’m really having is determining the permeability of the medium. I’ve been trying to find a formula to calculate the inductance of a coil wrapped around a solid core. I’ve built them before but they weren’t very efficient. For my senior project I’m doing high voltage electro magnetics, and I’m going to build a coil gun. Working alongside a capacitor, an inductor prevents sudden changes in the power supply’s output voltage and current.Hello everyone, first off I want to say that I’ve searched all over the place, and I even asked my mentor/physics teacher about this.
In power supplies, an inductor’s role is to prevent sudden changes in current used. This relegates the majority of their use cases to applications in areas where such an expense can be justified, such as telecoms equipment, radios, and power supplies. Inductors, due to the copper and iron materials needed to make them, tend to be expensive. Ferrite inductors are the most widely used type as it’s possible to finely control their permeability by tuning the ratio of ferrite to epoxy. When used in inductors, ferrite powder is mixed with an epoxy resin and molded to form a core around which a magnetic wire can be wound. (Source: RS Components)Ī ferrite is a ceramic material made by mixing and firing iron(III) oxide blended with small amounts of one or more additional metallic elements, such as nickel and zinc.
In almost all cases, you’ll find that an inductor in a system is formed around a core material-generally iron or iron compounds-to support the creation of a strong magnetic field.Ī ferrite core inductor manufactured by Wurth Elektronik. The different types of inductorĭifferent applications require different types of inductor. A magnetic wire is chosen to confine and guide the magnetic fields, and this is insulated to prevent problems like short circuits and breakdowns. The winding can form many shapes, including circular, rectangular foil, and square cross-section. The core material is an enamel-coated magnetic wire typically made of copper which is then coated in layers of insulating polymer material. Introduction to electronic compontents: Active vs. The design of an inductor is governed by electrical, mechanical, and thermal requirements of a given application. Inductance quantifies how much energy an inductor is capable of storing. The induced magnetic field also induces an electrical property known as inductance-the ratio of voltage to the rate of change of current. As such, inductors oppose any changes in current that pass through them. When the current flowing through the coil changes, the time-varying magnetic field induces voltage in the conductor with a polarity which opposes the change in current that created it.

This design was settled on following extensive trial and error methods that considered methods like Hanna curves and area-product.
Typically, an inductor will consist of an insulated wire that’s wound into a coil, much like a resistor. It’s a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. #expertĪccelerate power electronics development - Choose your tools wisely What is an inductor?Īn inductor is arguably the simplest of all electronic components. The inductor, which stores energy, supplies energy to the circuit to maintain current flow during “off” switching periods, thus enabling topographies where output voltage exceeds input voltage.ĭue to the way they work-by not only altering electric field but the magnetic field around it-many people struggle to understand them. Inductors are typically used as energy storage devices in switched-mode power devices to produce DC current.
