Abstract (en)
[origin: WO2014187439A1] The invention relates to a high-frequency oscillator (1) comprising an electric resonant circuit (2), a high-frequency welding system and to a method for controlling the frequency using a high-frequency oscillator, in particular in a high-frequency welding system. Said electric resonant circuit (2) comprises at least one electronic component (3) having an inductance and at least one capacitor (4) having a capacitance. In order to control the frequency of the electric resonant circuit in a fast and wear-resistance manner, at least one additional magnetic coil (6) is associated with the electronic component (3) and can electronically influence the inductance of the electronic component (3).
