In this paper, a proposed 1-bit hybrid full adder design employing both transmission gate logic and complementary metal– oxide–semiconductor (CMOS) logic is reported. The design is implemented for 1-bit Ripple Carry Adder and then is extended for 64-bit Ripple Carry Adder. The circuit is implemented using Mentor Graphics tools 130nm technology. The performance parameters such as delay, area, to...

A new topology of a hybrid distributed generator based on photovoltaic and wind-driven permanent magnet synchronous generator is proposed. In this generator, the sources are together connected to the grid with the help of only a single boost converter followed by an inverter. Thus, compared to earlier schemes, the proposed scheme has fewer power converters. Model of the proposed scheme in d-q a...

Due to development of the demand increasing of energy around the world and the decline of traditional energy sources in electricity generation the development orientation of power generation has been toward renewable energies. The use of these unfailing and renewable resources requires study substrates and new infrastructure in the transmission and distribution networks. Due to the power instab...

Mobile robots are often needed for long duration missions. These include search rescue, sentry, repair, surveillance and entertainment. Current power supply technology limit walking and climbing robots from many such missions. Internal combustion engines have high noise and emit toxic exhaust while rechargeable batteries have low energy densities and high rates of self-discharge. In theory, fue...

Renewable energy is derived from natural processes that are replenished constantly. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and bio-fuels and hydrogen derived from renewable resources. Each of these sources has unique characteristics which influence how and where they are used. This paper presents the model...

The power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. This paper presents modeling and optimization of a photovoltaic (PV)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in Rafsanjan, Iran. For this location, different hybrid systems are studied and ...
