A new single-phase 15-level inverter with a reduced number of components for the Solar PV application is proposed in this paper. It incorporate boost converter to extract energy from solar modules, aids generate fifteen stepped output voltage levels lower THD. The can improve efficiency and reduce losses, cost, complexity overall system. conventional will maximum MPPT(P&O). tested experimentall...

Distributed generation (DG) will play an important role in future power generation systems, especially in stand-alone applications. Three phase four-leg inverter is a well-known topology which can be used as an interface power converter for DGs. Thanks to the fourth leg to provide the neutral path, the four-leg inverter is able to supply balanced loads as well as unbalanced loads. In this paper...

The electrical power industry has grown rapidly and loads are changing from simple, non-electronic loads to electronic ones. These electronic loads draw a non-sinusoidal current even when the supply voltage is perfectly sinusoidal. In this paper PWM controller with dual feedback loop with simple single-stage single-switch input-current shaping circuit was designed, simulated and tested for AC/D...

let $g$ be a non-abelian group and let $z(g)$ be the center of $g$. associate with $g$ there is agraph $gamma_g$ as follows: take $gsetminus z(g)$ as vertices of$gamma_g$ and joint two distinct vertices $x$ and $y$ whenever$yxneq yx$. $gamma_g$ is called the non-commuting graph of $g$. in recent years many interesting works have been done in non-commutative graph of groups. computing the clique...

we study the exponential decay of global solution for an n-dimensional thermo-elasticity systemin a bounded domain of ℜn . by using the multiplier technique and constructing an energy functional welladapted to the system, the exponential decay is proved.
