Abstract
An inductor, in particular for magnetically coupled energy transfer, includes a coil carrier on which a first coil and a second coil are arranged. The second coil has an outer diameter D2 that is greater than an outer diameter D1 of the first coil. A magnetic core surrounds a longitudinal center axis of the first coil. The first coil is operated with a first operating frequency in a first power range, whereas the second coil is operated independently of the first coil with a second operating frequency in a second power range. As a result applications can be run in a simple and flexible manner in a low-power range and in a high-power range.
Claims15
An inductor, comprising:
- a coil carrier;
- a first coil arranged on the coil carrier for energy transfer in a first power range, the first coil having a first outer diameter;
- a second coil arranged on the coil carrier for energy transfer in a second power range, the second coil having a second outer diameter, wherein the second outer diameter is larger than the first outer diameter;
- a magnetic core surrounding a longitudinal center axis of the first coil;
- and
- a control unit that is designed such that the first coil and the second coil are operated independently of one another.
A method for the operation of an inductor, the method comprising the steps of:
- providing an inductor with a first coil and a second coil, a magnetic core that surrounds a longitudinal center axis of the first coil and a control unit that is designed such that the first coil and the second coil are operated independently of one another;
- operating the first coil with a first operating frequency in a first power range;
- and
- operating the second coil independently of the first coil with a second operating frequency in a second power range.
