Inductive charging is a method of moving power wirelessly. A power generating source system is placed near a power storing or power transferring system. An electromagnetic field is generated between the two objects and power is moved from one system to the other. Inductive charging is a way of moving power from a main system to a subsystem such as moving the power from the power grid to a local...

For magnetic-coupled resonator wireless power transmission (WPT) systems, higher power transfer efficiency can be achieved over a greater range in comparison to inductive-coupled WPT systems. However, as the distance between the two near-field resonators varies, the coupling between them changes. The change in coupling would in turn vary the power transfer efficiency. Generally, to maintain hig...

Wireless Power Transfer(WPT) is a popular research field in recent years and can be categorized into three approaches: inductive coupling, laser beaming and microwave power transmission(MPT). MPT system operates at the microwave frequency and transfer the energy over more than a few wavelengths. It has its unique advantages of supplying power to nonaccessible and mobile receivers. The overall e...

Recently, dry power transformer (Dryformer) that performs one step transformation from transmission to distribution voltage levels, has been introduced [1]. The Dryformer (dry power transformer) combines the features of power transformer with that of station distribution transformer, by utilising XLPE insulated round conductor cable for winding construction. The parameters of the cable winding ...

in this paper, first, a new criterion, titled “surplus percent of the customers” is defined for static transmission expansion planning in restructured power systems. then by a simple example, the new criterion is compared with some already presented market-based criteria and it is shown that the new criterion can realistically evaluate the transmission network expansion from the market view. in...
