wireless power transfer using inductive coil ppt

Resonant inductive coupling or electrodynamic induction is the near field wireless transmission of electrical energy between two magnetically coupled coils that are part of resonant circuits tuned to resonate at the same frequency. This process occurs in a resonant transformer, an electrical component which consists of two high Q coils wound on the same core with capacitors connected across the windings to make two coupled LC circuits. Resonant transformers are widely used in radio circuits as b ....etc

The superconducting fault current limiter (SFCL) is one method to solve the conflict between the rated value of breaker and fault current. With the increase of electricity demand and change of concerning environment, the capabilities of renewable energy generation systems are being expanded.Renewable energy sources considered as clean and prospective energy sources of the future world.A high temperature superconducting fault current limiter (SFCL) can be solution to reduce the level of short-circuit current during fault. ....etc

Increases in the installed capacity and the interconnection of the transmission networks lead to possibility of
fault currents. Fault currents results from various kinds of high voltage stresses caused by lighting and short circuits
or other system disturbances, which send a surge power through the grid.
One of the usages of superconductors is protecting electronic devices and systems from short circuit .
There are three types of superconductors fault current limiters (SFCL): resistive, inductive and hybrid. Protection of
scheme from cu ....etc

wireless mobile phone charger using inductive coupling

Abstract

A wireless power transfer (WPT) using inductive coupling for mobile phone charger is studied. The project is offer to study and fabricate solar WPT using inductive coupling for mobile phone charger that will give more information about distance is effect for WPT performance and WPT is not much influenced by the presence of hands, books and types of plastics. The components used to build wireless power transfer can be divided into 3 parts components, the transceiver for power tran ....etc

This method is also called potier method. In the operation of any alternator, the armature resistance drop and armature leakage reactance drop IXL are actually e.m.f. quantities while the armature reaction is basically m.m.f. quantity. In the synchronous impedance all the quantities are treated as e.m.f. quantities as against this in M.M.F. method all are treated as m.m.f. quantities. Hence in both the methods, we are away from reality.
Note : This method is based on the separation of armature leakage reactance and armature reaction effects. ....etc
