Benefits of technology

The technical effect of this patent text is to provide a way to control frequency without wearing down equipment and in response to rapid changes in usage. This results in higher control accuracy.

Problems solved by technology

However, these high frequency oscillators have relatively low frequency stability, i.e. a low quality factor.
However, in case of rapid load changes, the frequency correction cannot happen at sufficiently short notice.
In particular, load changes that are shorter than 300 milliseconds cannot be corrected, the control being additionally complicated by a relatively strong tendency to overshoot.
Furthermore, the necessary mechanical system is subject to wear.

Embodiment Construction

[0025]FIG. 1 shows a schematic diagram of a high frequency oscillator 1 comprising an electric resonant circuit 2. In the electric resonant circuit 2, the electronic component 3 that provides an inductance L is a coil. In addition, the resonant circuit comprises a capacitor 4 having a capacitance C. In its structural principle, the resonant circuit is a conventional LC resonant circuit. In this example, the electronic component 3 is designed as a coil with at least one copper tube. However, it is also possible to provide several coils as well as several capacitors.

[0026]The electronic component 3 is passed through a ring 5 made of a ferromagnetic material, around which a magnetic coil 6 is wound. The magnetic coil 6 is integrated in a control circuit 8 that comprises a controllable direct current source 7.

[0027]Through appropriate actuation of the direct current source 7, the magnetic coil 6 generates a magnetic field, which is superimposed on the field of the electronic component 3...

Abstract

A high-frequency oscillator includes an electric resonant circuit, and a high-frequency welding system and a method for controlling the frequency uses a high-frequency oscillator, in particular in a high-frequency welding system. The electric resonant circuit includes at least one electronic component having an inductance and at least one capacitor having a capacitance. At least one additional magnetic coil is associated with the electronic component and can electronically influence the inductance of the electronic component.
