This paper presents 500 KW three phase standalone photovoltaic systems supplying pumping station consist of four pumps 80 KW rating. The system utilizes a two stage energy conversion power conditioning unit topology composed of a DC-DC boost converter and three level-three phase voltage source inverter (VSI). The Boost converter in this paper is designed to operate in continuous mode and contro...

Effects of magnetic saturation on various equivalent circuit models of an induction motor are studied. The parameters of 2.2-kW and 37-kW motors with closed rotor slots are analyzed using finite element computations. Both skewed and unskewed rotor slots are studied. The magnetizing inductance not only depends on the main flux, but is also dependent on the rotor current, especially if the rotor ...

large-scaled blade has posed many problems related to design and production. After introducing the features of blade with thick airfoils and flatback, based on relevant parameters of Huaren 100 kW wind turbine, the paper designed blade with thick airfoils and flatback, introduced blade parameter design, and analyzed the aerodynamic performance of blades using GH bladed software, obtaining the r...

KW-3902 (a newly synthesized adenosine A(1)-receptor antagonist) has potent diuretic and renal protective activities and was formulated in lipid dispersion systems, i.e., lipid emulsions and liposomes. The objective of the present study was to evaluate the carrier potential of these lipid dispersion systems, which is explained here as the ability of the formulation to retain the drug in its dis...

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

In [KW] it was proved that for every boolean function $f$ there exist a communication complexity game $R_f$ such that the minimal circuit-depth of $f$ exactly equals to the communication complexity of $R_f$. If $f$ is monotone then there also exists a game $R_f^m$ with communication complexity exactly equals to the monotone depth of $f$. It was also proved in [KW] that the communication complex...

Development of a 20 kW Solid State Power Amplifier (SSPA), at 352 MHz, is in progress at RRCAT. This design uses radial dividing and combining architecture. As a part of this system, two high power (4 kW) combiners have been designed and developed. First one is 8 way with output ports in opposite but parallel direction to input port. Second one is 16 way with radial output ports. This paper des...
