The transfer of power from source to receiver is a technology that has existed for over a century. Wireless power transfer (WPT) has been made feasible in recent years due to advances in technology and better implementations of transfer techniques, such as Microwave Power Transfer (MPT). The MPT system works by converting power to microwaves through a microwave generator and then transmitting t...

course contents of b.sc. and even m.sc. or ph.d. programs in electrical power engineering in our country is mainly based on conventional; technologies employed in different sectors of generation, transmission and distribution of electricity. electricity industry in iran has been successful in localization and transfer of technology from foreign countries and research centers and universities ha...

This letter investigates the relationship between antenna position and data communication performance in a magnetic resonance wireless power transfer (MRWPT) system. In MRWPT information such as the types of equipments, the required amount of electrical power, or the timing of power transfer should be exchanged. It is assumed here that power transfer coils in the MRWPT system are employed as an...

Electric power industries throughout the world have been restructured to introduce competition among the market participants and bring several competitive opportunities. Open access to the transmission system places an emphasis on the intensive use of the interconnected network reliably, which requires knowledge of the network capability. Available Transfer Capability (ATC) is a measure of the ...

This paper discusses a wireless power transfer system equipped with multiple coils for underwater vehicles.The discussed in this includes dual-receiving mounted on vehicles that can receive electric at the same time,making it possible to expect an increase transmission and improved redundancy of system.This examines receiving voltage,transmission efficiency when are misaligned.The results test ...

This quick calculation implies that the only way to achieve the rated maximum power dissipation is to have a “perfect heatsink” or an “infinite heatsink.” The thermal impedance used in the calculation is from the junction to case only and assumes zero impedance into the ambient. This is practically impossible to achieve. Further, the ambient was assumed to be 25C (room temperature) which may no...

This study presents a complete wave-to-wire model in which a novel wave energy converter control approach based on adaptive vector control is introduced. The proposed control for maximum power absorption of the primary resource is included, as well as the grid interconnection topology and required controllers, needed for processing the power over the entire wave energy conversion chain. Thanks ...

Solar panels have great potential as energy harvesting power sources—they just need batteries to store the harvested power and to provide carry-though during dark periods. Solar panels are relatively expensive, so extracting maximum power from the panels is paramount to minimizing the panel size. The tricky part is a balancing of solar panel size with required power. The characteristics of sola...

Light rail vehicles (LRVs) are increasingly in demand to sustainably meet the transport needs of growing populations urban centres. LRVs have commonly been powered from grid by direct-contact overhead catenary systems (OCS); however, catenary-free systems, such as via a “hidden rail”, popular for new installations. Wireless power transfer (WPT) is an emerging (PT) technology e-transport with se...

We construct the transfer matrix for the ghost sector of partially quenched QCD. This transfer matrix is not hermitian, but we show that it is still bounded. We thus expect that all euclidean correlation functions will decay exponentially with distance (up to possible powers), and demonstrate that this is indeed the case for free ghost quarks.
