Abstract
A power supply system includes a power converter configured to generate a high-frequency power signal and connected to a load to supply a plasma process or a gas laser process with power. The power converter has at least one amplifier path including at least one amplifier, an analog signal generated from a digital signal by a digital-analog converter (DAC) being supplied to the amplifier path, and a logic circuit unit configured to generate the digital signal and connected upstream of the DAC. The logic circuit unit has a signal data memory for storing signal data values for generating an analog signal form, an amplitude data memory for storing amplitude data values for influencing amplitudes of the analog signals, and a multiplier for multiplying the signal data values by the amplitude data values. The power converter includes an adjustable voltage supply for supplying the amplifier with a voltage.
