Induction heating has become a meandering side interest here at oschemes, due to our desire to build a sweet induction forge for a metalsmithing buddy. Inductors, being just coils of copper wire, will allow DC to pass easily, but when AC is applied, inductors create an opposition to current flow that increases, as the frequency of the alternating current increases. Coils placed close as seen on picture: 1. Inductance, L (measured in Henries, H), is the measure of a magnetic field created by a current flowing through a coil of wire. How to identify inductor markings. with IGBT The principle of induction heating is simple. Just finished mine and followed your blog thoroughly and i am very happy with result. Fixing the inductor • There are ways to build inductors with less parasitic capacitance, so a higher SRF • This typically involves special winding geometries, sectioned windings, insulating layers, or magic! • They can cause the inductor to be physically larger, and more expensive, and certainly harder to build.
