    Abstract: When treating items with high-frequency electric power there is a need for making a correct impedance matching can be made between a generator and a tool holding the item to be treated, and there is a need to avoid the formation of standing waves in transmission lines, etc.. In addition there is a need to be able to treat items having a dimension which is comparable with the wave length at the frequency used, and to be able to exactly measure the power transmitted to the treated item. This object is attained by means of a method which comprises tuning of a circuit to resonance and adjustment of an impedance transforming ratio to correct impedance matching, as well as correction of said adjustments during the treatment of the item. For carrying out the method an apparatus is provided which comprises at least two variable impedances as well as means for detecting deviation from resonance and from correct impedance matching. The two variable impedances are preferably a continuously variable capacitor and a continuously variable coil, and the detection is performed by measuring of the standing wave ratio on the transmission line.

    Abstract translation: 当处理具有高频电力的物品时,需要在发电机和保持待处理物品的工具之间进行正确的阻抗匹配,并且需要避免在传输线路中形成驻波 等等。此外,需要能够处理具有与使用的频率下的波长相当的尺寸的物品,并且能够精确地测量传递到被处理物品的功率。 该目的通过一种方法来实现,该方法包括将电路调谐到谐振和调整阻抗变换比以校正阻抗匹配,以及在处理该项目期间校正所述调整。 为了实施该方法,提供了一种包括至少两个可变阻抗的装置以及用于检测偏离谐振和正确阻抗匹配的装置。 两个可变阻抗优选为连续可变电容器和连续可变线圈,并且通过测量传输线上的驻波比进行检测。
