Then k is assumed to have a value less than 0.5, and the inductors are said to be ‘loosely coupled’ or if the inductors share a common core with zero spacing between them, they are said to be ‘tightly coupled’ and k is assumed to have a value

Coupled Inductors
www.maplesoft.comFigure 1: Two coils are magnetically coupled, wound around a magnetic core. With coupled inductors, such as those shown in figure 1, two wires are wrapped around a magnetic core. In this diagram, note that the two wires are wrapped around the core in opposite directions and produce the same polarity of voltage. This is due to Lenz's law. A

www.psma.comMar 17, 2020 · Leakage inductance parasitic effect produced by the imperfect magnetic coupling between the transformer windings. The magnetic flux generated in the primary winding is never transferred 100% to the secondary winding. This leakage inductance depends basically on: - The winding geometry - The core geometry - Number of turns
