Calculation of Leakage Inductance for High-Frequency Transformers
IEEE Transactions on Power Electronics, 2015Frequency-dependent leakage inductance is often observed. The high-frequency eddy current effects cause a reduction in leakage inductance. The proximity effect between adjacent layers is responsible for the reduction of leakage inductance. This paper gives a detailed analysis of high-frequency leakage inductance and proposes an accurate prediction ...

A novel transformer with adjustable leakage inductance
International Journal of Applied Electromagnetics and Mechanics, 2017Considering the challenge that the parameter of inductor is fixed and its adjustment is difficult in traditional power electronic circuit, herein we present a newly structural transformer with adjustable leakage inductance which integrates transformer and inductor. Its leakage inductance can be adjusted online. Secondary winding of the newly structure

Saturated leakage reactances of cage induction motors
Proceedings of the Institution of Electrical Engineers, 1969The paper presents a method of predicting the saturation of the leakage reactances of cage induction motors. It commences with a discussion of leakage fluxes and reactances and the manner in which they are affected by magnetic saturation. The calculation of the components of leakage reactance under unsaturated conditions is described.

Calculation of leakage inductance in transformer windings
IEEE Transactions on Power Electronics, 1994A formula is presented to calculate mutual impedance between transformer windings on ferromagnetic cores. The formula is based on the solution of Maxwell's equations for coils on ferromagnetic cores and as such offers the ultimate in accuracy. The formula is frequency dependent, taking into account the effect of eddy currents in the core on the flux ...

Modeling of magnetizing inductance and leakage inductance in a matrix transformer
IEEE Transactions on Power Electronics, 1993Winding and core geometries are described for a matrix transformer constructed from integrated core and z-folded flex circuits. The magnetizing inductance is derived using the reluctance method and exploiting structural periodicity and symmetry. The internal leakage inductance is computed from the magnetic field distribution, and the interconnect ...

Use of the External Magnetic Field for Induction Machine Leakage Inductance Distinction
IEEE Transactions on Magnetics, 2010This paper is about the exploration and the analysis of the AC rotating machine external magnetic field. An experimental procedure is presented: it makes it possible to distinguish the stator and rotor leakage inductances which occur in the induction machine single phase equivalent circuit.

Double star induction machine modelling: Impact of the stator mutual leakage inductance
International Journal of Applied Electromagnetics and Mechanics, 2017This article discusses the modeling of double star induction machines (DSIM). Its main objective is to study the impact of the stator mutual leakage inductance on the modeling of such machines, in steady-state and dynamic operations. For that purpose, experimental and simulation results are conducted on two squirrel cage induction machines with equal ...

An induction motor model with deep-bar effect and leakage inductance saturation
Archiv für Elektrotechnik, 1978A two-phase dynamic induction motor model is derived which includes the effects of rotor bar eddy currents and leakage inductance saturation. The model is based on approximate analysis of the air-gap and slot electromagnetic fields which leads directly to lumped circuit equations.

2007 European Conference on Power Electronics and Applications, 2007
In this paper, the influences of the magnetic inductance, leakage inductance and saturable inductor on the behaviour of the active clamp forward are analyzed, and their mathematic solutions are given. Based on the analysis, the other topology variant is proposed, which can be used to reduce the oscillation across the freewheeling switch and improve the
