| 摘要 |
The invention relates to an impedance means (5) having a first conductor (10, L1) and a second conductor (40, L2), the first and second conductors being positioned in relation to each other so as to provide magnetic coupling (L12) between them. The invention also relates to a method for controlling the impedance of the impedance means. The method comprises the steps of receiving, in the first conductor (10, L1), a first electric signal having a first amplitude (I1) and a first phase angle ( theta 1) and generating a second electric signal having a second amplitude (I2) and a second phase angle ( theta 2). The method includes delivering the second electric signal to the second conductor (40, L2) and controlling said second phase angle ( theta 2). |
