Mechanism of phase formation in Pb(ZrxTi1-x)O3 synthesized by a partial oxalate method
(1996-06-01)
The phase formation mechanism, as well as the morphotropic phase boundary, of lead zirconate titanate (PZT) processed by a partial oxalate method was investigated by simultaneous thermal analysis (TG-DTA) and by qualitative ...

A new three-phase transformer modeling for three-phase harmonic analysis in distribution systems
(Institute of Electrical and Electronics Engineers (IEEE), 2005-01-01)
This work presents a new three-phase transformer modeling suitable for simulations in Pspice environment, which until now represents the electrical characteristics of a real transformer. It is proposed the model comparison ...
Proposal of a simplified process to correct the phase decoupling using modal analysis
(2012-12-11)
Modal analysis is widely approached in the classic theory of transmission line modeling. This technique is applied to model the three-phase representation of conventional electric systems taking into account their self and ...
Error analysis of phase detector based on Clarke transform and arctangent function in polluted grids
(Elsevier Science Sa, 2015-06)
Abstract Extracting phase information from a three-phase disturbed signal is a recurrent topic in power systems. The phase detector based on the Clarke transform and the arctangent function is a widely used technique to ...
Analysis of the Transformer Influence on a Three-Phase Dual Active Bridge DC-DC Converter
(Institute of Electrical and Electronics Engineers, 2016-07)
In this work, the impact of the high-frequency transformer on the three-phase dual active bridge DC-to-DC converter operation is investigated, using four transformers with different connections: star-star, delta-delta, ...
Completeness of beta-phase decomposition reaction in Cu-Al-Ag alloys
(Springer, 2012-08-01)
The completeness of beta-phase decomposition reaction in the Cu-11wt%Al-xwt%Ag alloys (x = 0, 1, 2, and 3) was studied using differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and optical microscopy (OM). ...
