| Popis: | The concept of wireless power transfer technology is explained based on the principle of magnetic induction and magnetic resonance. Two technologies, magnetic induction and resonance, for wireless power transfer are compared in terms of expense, equivalent circuit, physics, loss, and performance. In magnetic induction, the magnetic field of one coil passes through the other coil. Two coils may be physically contained in a single unit, such as the primary and secondary sides of a transformer, or may be separated. In magnetic resonance, high-quality factor resonators enable efficient energy transfer at lower coupling rates, i.e., at greater distances and/or with more positional freedom than is otherwise possible. |
