Pulse transformer leakage inductances computation

2008 18th International Conference on Electrical Machines, 2008
This paper describes a semi-analytical modeling of an industrial electrical system operating in a pulse mode. It focuses principally on the transformer leakage inductances computation. First, the implemented analytical model is presented. It takes into account nonlinear elements behaviors, such as transformers, as well as other elements that behavior ...

An improved estimation of the induction machine leakage inductances

IEEE Transactions on Industrial Electronics, 1999
An alternative method for the determination of the induction machine leakage inductances is proposed. The stator transient inductance is the only parameter needed, besides the nameplate data. Results show the accuracy of the technique.

Inductance characterization of high-leakage transformers

Eighteenth Annual IEEE Applied Power Electronics Conference and Exposition, 2003. APEC '03., 2004
In this paper the inductances of high-leakage transformers are investigated by analysis, measurement, and finite-element simulation. Series-coupling tests, featuring differential coupling (series opposing) and cumulative coupling (series aiding), are conducted in addition to the standard open-circuit and short-circuit tests.

A Transformer with Adjustable Leakage Inductance

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
The leakage inductance of the transformer employed in a series resonant converter can be used for resonance to make the device more compact. The value of this inductance should be controllable and sufficient large. In this paper the novel structure of a transformer with adjustable leakage inductance is proposed and the design methodology is presented ...

Zigzag leakage of induction motors

Proceedings of the American Institute of Electrical Engineers, 1907
Various formulas have been given heretofore for the predetermination of the leakage coefficient of induction motors, but the results derived from these formulas are so divergent that the formulas themselves are rather discredited. It seems to the writer that the following study about the values of the zigzag leakage may help to clear this somewhat ...

Skew leakage in induction machines

European Transactions on Electrical Power, 1994
AbstractMost induction motors have their rotor slots skewed, i. e. twisted away from the axial direction, with the intention to reduce harmful slot harmonic effects. As skewing affects the magnetic coupling between primary and secondary windings, also the fundamental harmonic performance is involved.
