In the literature, it is well known that transformers and cables have excessive losses or overheating under non-sinusoidal current conditions. Accordingly, they have reduced current carrying capabilities (or loading capabilities) for that kind of conditions. This paper aims to employ passive filters for the effective utilization of the cables and transformers in the non-sinusoidal systems. Cons...

Title of Document: A NON-LINEAR DAMAGE MODEL WITH LOAD DEPENDENT EXPONENTS FOR SOLDERS UNDER SEQUENTIAL CYCLIC SHEAR LOADS Elviz George, Ph.D., 2015 Directed By: Professor Michael G. Pecht, Department of Mechanical Engineering The damage state of a material subject to cyclic loads is often characterized by the cycle ratio of applied cycles to the number of survivable cycles. The damage in a mat...

Land-based activities, including deforestation, agriculture, and urbanisation, cause increased erosion, reduced inland and coastal water quality, and subsequent loss or degradation of downstream coastal marine ecosystems. Quantitative approaches to link sediment loads from catchments to metrics of downstream marine ecosystem state are required to calculate the cost effectiveness of taking conse...

Computation of active and reactive powers is a crucial step in droop-controlled single-phase voltage source inverters (VSIs) standalone microgrid since the performance stability power-sharing strategy are strongly influenced by its speed accuracy, especially case non-linear loads. Here, an improved among VSIs islanded microgrid, considering DC component nonlinear loads presented. To achieve thi...

Prominent harmonics in IT offices are essentially due to the presence of SMPS in computers large numbers. In a three-phase, fourwire system, current harmonics leads to flow zero sequence current in neutral conductor, increased losses in motors, false tripping of circuit breakers. In this paper, VSI is designed as a compensator based instantaneous reactive power theory. And is used to mitigate t...
