The market for power semiconductor modules is spreading not only to general-purpose inverters, servo motor drives, NC machine tools and elevators but also to new applications through the realization of electric vehicles and renewable energy systems. Fuji Electric has developed various power modules in response to market needs, and as the market expands in the future, the required performance fo...

Technology decomposition and technology mapping are two potential stages for minimizing circuit power during logic synthesis. Since power in CMOS circuits is directly dependent on the extent of circuit switching activity, we present a novel procedure to construct a low-activity circuit structure in the technology decomposition stage. This would result in low-power circuits when mapped. The algo...

The fast frequency response (FFR) function in renewable energy source (RES)-based power stations has proved to be able improve the stability of systems with high RES penetration significantly. However, most current FFR functions photovoltaic (PV) typically show deviations and unnecessary loss issues that are caused by inadequate station distribution strategies. This is particularly important ca...

quantum-dot cellular automata (qca) has low power consumption and high density and regularity. qca widely supports the new devices designed for nanotechnology. application of qca technology as an alternative method for cmos technology on nano-scale shows a promising future. this paper presents successful designing, layout and analysis of multiplexer with a new structure in qca technique. in thi...

Power supply technology is a basic technology that supports all types of electronic equipment. Switching power supplies, in particular, are characterized by small size, light weight and high efficiency and are the mainstream technology used in power supplies at present. In recent years, with the advent of an advanced information and communications-oriented society, trends toward personalization...

a high accurate and low-voltage analog cmos current divider which operates with a single power supply voltage is designed in 0.18µm cmos standard technology. the proposed divider uses a differential amplifier and transistor in triode region in order to perform the division. the proposed divider is modeled with neural network while tlbo algorithm is used to optimize it. the proposed optimization...

This paper proposes novel Fuel Cell Auxiliary Power Unit (FCAPU) for J150+ aircraft application. The primary version of APU in J150+ aircraft is a gas turbine Auxiliary Power Unit (APU) which is based on gas turbine jet engine but in the suggested FCAPU, the generated electrical power is achieved from chemical energy with higher efficiency. The Solid Oxide Fuel Cell (SOFC) technology is used to...

In this paper we outline the ways in which thermal and spectral remote sensing can be used to diagnose and monitor effects of environmental stresses on plants. Following an introduction to the theory and practice of using thermal sensing to study plant water relations and stresses involving stomatal closure, the discussion is widened to cover a range of imaging technologies. Particular emphasis...
