BPS Configuration of Supermembrane With Winding in M-direction [PDF]
We study de Wit-Hoppe-Nicolai supermembrane with emphasis on the winding in M-direction. We propose a SUSY algebra of the supermembrane in the Lorentz invariant form.

An Inductive Active Filtering Method for Low-Voltage Distribution Networks
Three-phase unbalanced and nonlinear loads aggravate harmonic problems in low-voltage distribution networks. In this paper, a hybrid inductive and active filter (HIAF) system with a Ddy converter transformer is proposed.

Eddy-current loss in the rotor magnets of permanent-magnet brushless machines having a fractional number of slots per pole [PDF]
We develop an analytical model for predicting the eddy-current loss in the rotor magnets of permanent-magnet brushless machines that have a fractional number of slots per pole, when either all the teeth or only alternate teeth are wound, and in which the

Analysis of AC winding loss of permanent magnet synchronous traction motor with high power
In a multiple-pole and high-power PMSTM with high fundamental frequency, the harmonic frequency of the internal magnetic field increases accordingly. The harmonic magnetic field will induce eddy current in the winding, resulting in high-frequency eddy ...
