This paper proposes a single stage solar power generation with boost dc-ac inverter by simple control technique. The boost dc-ac inverter converts and boosts a low output dc voltage of the solar pv array into a 220Vrms ac voltage at a fundamental frequency of 50Hz in single stage. A simple Modified Non-Linear State Variable Structure (MNLSVS) closed loop control technique is proposed to keep th...

The objective of this work is to study the contribution that use multi-level inverter can make compared a conventional two-level inverter, in wind power production line (WPG) associated with doubly fed induction generator (DFIG). DFIG driven by variable speed turbine and operates maximum point tracking (MPPT) mode, for optimum efficiency. rotor supplied DC/AC five levels MPC structure, controll...

Thyristor rectifiers are widely used in electric railways in order to control the speed. As a consequence of their usage in addition to substantial input lead current, an enormous amount of harmonics is injected into the grid. To avoid such harmonics as well as reactive power compensation, reactive power hybrid filters consisting of active and passive filters are utilized. Regarding different p...

The smart load phenomenon of electric spring has been proven to be an important aid the distribution network in terms voltage stability. While performance ES is commendable, its operational range presents a significant challenge. effectiveness depends on various factors, including choice control structure, ratio, placement, and non-critical power factor. To address challenges regarding noncriti...

evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

Congenital tyrosine hydroxylase deficiency (THD) is found in autosomal-recessive Dopa-responsive dystonia and related neurological syndromes. The clinical manifestations of THD are variable, ranging from early-onset lethal disease to mild Parkinson disease-like symptoms appearing in adolescence. Until 2014, approximately 70 THD patients with a total of 40 different disease-related missense muta...
