DC-Bias Characteristics of Magnetic Materials for a Linear DC Motor

Journal of the Magnetics Society of Japan, 1997
This paper describes the dc-bias characteristics of five magnetic materials used in a linear dc motor (LDM): three block materials−carbon steel (S45C), pure iron (SUYB1) and cast iron (FCD450), and two laminated materials− non-oriented silicon steel sheets (35H440) and oriented sili-con steel sheets (23ZH100). The following conclusions are reached: (1)

Analysis of switching effects in DC-DC converters via bias point computation [PDF]

2007 18th European Conference on Circuit Theory and Design, 2007
The paper describes a method for finding steady states in switched DC-DC converters, which is based on the SPICE bias point computation rather than a time-consuming transient analysis. The switched converter is modeled by unified substitutive circuits whose DC analysis determines directly the limit values of steady-state circuit variables at time ...

Radiation Pattern Reconfigurable MIMO Antenna With Practical DC Bias Network [PDF]

, 2022
This paper presents a radiation pattern reconfigurable (RPR) based multiple-input multiple-output (MIMO) antenna. The proposed antenna operates at 3.5 GHz for all switching conditions with S21 results of less than -20 dB.

Artificial Grain Boundaries Created by Freestanding Membrane Transfer Reveal Angle‐Dependent Ferroelectric Switching and Leakage in BaTiO3 [PDF]

Advanced science
Artificial grain boundaries are created in BaTiO3$\text{BaTiO}_3$ thin films by freestanding membrane transfer, enabling direct isolation of a single boundary. Local ferroelectric switching and leakage are found to concentrate at the grain boundary, while increasing misorientation systematically enhances conduction.

Time-frequency analysis of DC bias vibration of transformer core on the basis of Hilbert–Huang transform [PDF]

, 2016
This paper presents a time–frequency analysis of the vibration of transformer under direct current (DC) bias through Hilbert–Huang transform (HHT). First, the theory of DC bias for the transformer was analyzed. Next, the empirical mode decomposition (EMD)
