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)

V-I characteristics in the vicinity of order-disorder transition in vortex matter

, 2002
The shape of the V-I characteristics leading to a peak in the differential resistance r_d=dV/dI in the vicinity of the order-disorder transition in NbSe2 is investigated. r_d is large when measured by dc current. However, for a small Iac on a dc bias r_d

Design of single-phase phase-locked loop based on cascaded second-order generalized integrator

Dianzi Jishu Yingyong
Due to the inevitable existence of various DC bias and higher harmonics in the current power grid, the traditional phase-locked loop (PLL) based on Second-order Generalized Integrator (SOGI) is sensitive to DC bias and has insufficient filtering ability ...

Shubnikov-de Haas oscillations of a single layer graphene under dc current bias

, 2011
Shubnikov-de Haas (SdH) oscillations under a dc current bias are experimentally studied on a Hall bar sample of single layer graphene. In dc resistance, the bias current shows the common damping effect on the SdH oscillations and the effect can be well ...
