Coupling inductance
Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of the current, and follows any changes in current. From Faraday's law of … See more The history of electromagnetic induction, a facet of electromagnetism, began with observations of the ancients: electric charge or static electricity (rubbing silk on amber), electric current (lightning), and magnetic attraction ( See more If the current through a conductor with inductance is increasing, a voltage $${\displaystyle v(t)}$$ is induced across the conductor with … See more Mutual inductance is defined as the ratio between the EMF induced in one loop or coil by the rate of change of current in another loop or coil. … See more 1. ^ The integral is called "logarithmically divergent" because $${\displaystyle \ \int {\frac {1}{x}}\ \mathrm {d} x=\ln(x)\ }$$ for See more A current $${\displaystyle i}$$ flowing through a conductor generates a magnetic field around the conductor, which is described by See more In the most general case, inductance can be calculated from Maxwell's equations. Many important cases can be solved using simplifications. Where high frequency currents are considered, with skin effect, the surface current densities and magnetic field may be … See more • Electromagnetic induction • Gyrator • Hydraulic analogy • Leakage inductance See more WebAug 8, 2024 · The leakage inductance and primary/secondary capacitance are mutually exclusive and are governed by the distance between the windings and the unwounded core. As a result of this, it is difficult to achieve both low capacitive coupling and a high degree of inductive coupling in a power transformer [ 33, 34 ].

WebSep 18, 2024 · The primary has an inductance of 38 uH and couples to the secondaries with a turns ratio of 2:1 and 2:1.1. The 2:1 coupling means that the secondary inductance is ( 1: 2) 2 x 38 uH = 9.5 uH. The other secondary has a turns ratio slightly less (2:1.1) and therefore has an inductance of 11.5 uH.
