Introduction to adaptation networks In every plasma treatment system, the adaptation network constitutes a critical component. The adaptation network’s purpose is to transform the complex (*) and variable impedance in keeping with the process conditions, in a purely resistive impedance, with a 50 ohm fixed value necessary for the correct operation of the coaxial transmission line and the RF generator.
GK’s two-decade experience in low-pressure plasma systems has made possible the implementation of a family of flexible and reliable automatic matching networks. Tuners AM1 and AM2 present the same L-circuit configuration, the same general dimensions and the same interfaces, but they are diversified for the different voltage and current ratings. The AM1 model powers loads of up to 15Amp and 2500V AC+DC and deploys variable air-capacitors.
*(in other words, made up by a resistive component, and therefore dissipative, and by a reactive component that must be "cancelled").
The interface board GGK-CS14 has the task to put in communication the Gambetti's automatic matching network AM1 with the Advanced Energy’s CESAR ® platforms.
The board provides to the AM1 the necessary tools to interpret the command signals of the CESAR ® platforms, in a transparently way to the end user.
Thanks to this it is possible to control the AM1 directly from the generator, enabling the operator to manually adjust, directly from the generator panel, the capacitor’s positions of the AM1.
In addition, it becomes possible to use the presets provided by the generators, thereby taking advantage of the automatisms already present in the CESAR ® platforms.
The card is designed to be mounted directly on the body of the AM1, it does not require any kind of maintenance and training costs.
We can realize this kind of interface cards, including other brands of 13.56 MHz RF power supply with power up to 600 W.
