The inherent nature of normal boost converter has more voltage stress across the power electronics switch and ripple. The presented formation of the front end rectifier stage for a photovoltaic (PV) organization is mainly used to give the supply. Further increasing of the solar efficiency is achieved by connecting the zero voltage soft switching boost converter. The zero voltage boost converter...

The paper presents a comparative study of three topologies of recently developed voltage-fed z-source inverter (ZSI) such as simple ZSI, quasi-ZSI and trans-ZSI. Different control techniques, proposed earlier for simple ZSI such as simple boost control, maximum boost control and constant boost control, have been applied here for all type of ZSI topologies. The detailed comparative evaluation of...

Tangent bifurcation is a special bifurcation in nonlinear dynamic systems. The investigation of the mechanism of the tangent bifurcation in current mode controlled boost converters operating in continuous conduction mode (CCM) is performed. The one-dimensional discrete iterative map of the boost converter is derived. Based on the tangent bifurcation theorem, the conditions of producing the tang...

The increase in levels of blood nicotine that occurs from smoking a single cigarette, sometimes referred to as a “nicotine boost,” is an individualized measure of how much nicotine has been extracted from smoking a cigarette. This study investigated the demographic, smoking status, and psychological predictors of nicotine boost in a sample of 190 treatment-seeking smokers. Boost was assessed by...

Two essential technologies for a 3D Solid State Drive (3DSSD) with a boost converter are presented in this paper. The first topic is the spiral inductor design which determines the performance of the boost converter, and the second is the effect of TSV’s on the boost converter. These techniques are very important in achieving a 3D-SSD with a boost converter. In the design of the inductor, the o...

The LM5032 dual current mode PWM controller contains all the features needed to control an interleaved boost converter. The two outputs operate 180 degrees out of phase and have separate current limit inputs for each channel. In addition to a high input voltage range, the controller contains all the auxiliary features needed to control a complete converter. Introduction A basic boost converter ...

From the outset of his bid for the presidency, Barack Obama has promised to make sweeping changes in the areas of energy, science, and climate change; but few could have predicted a year ago how quickly these commitments would be realized and at what scale. By signing the economic stimulus package into law earlier this month, however, the new president has authorized enormous cash infusions int...

Japanese primate researchers have always had an advantage: the world’s most northerly species lives in their backyard. For 60 years researchers based at Kyoto University have studied their native Japanese macaques on the island of Koshima. The work was begun by Kinji Imanishi and distinguished students have kept Kyoto at the forefront of primate research. The university’s primate research centr...

It was in a greenhouse in Oakland, California in 1989 that I began to question what I thought I knew about the use of transgenes in agriculture. I had been urged to look at some transgenic petunia plants by a company to which I was a scientific advisor. The plants in front of me had deep purple petals with many white segments. Some of the plants had all-white flowers. The white segments and the...

One of the basic requirements of service providers is to deliver fast processing, highly available, scalable, redundant and unobtrusive AAA services. In this paper we present incorporation of Diameter service into a legacy switching system. Our approach is based on a component architecture and the use of open source software to speed-up the development cycle. The main idea is to multiply critic...
