Abstract
A power supply system includes a power converter configured to generate a high-frequency power signal and be connected to a load to supply a plasma process or gas laser process with power. The power converter includes at least one amplifier stage having first and second amplifier paths each having an amplifier. The first and second amplifier path are connected to a phase-shifting coupler unit that is configured to couple phase-shifted output signals from the first and second amplifier paths to form the high-frequency power signal. At least one amplifier of the first and second amplifier paths includes a field effect transistor implemented in a semiconductor device with a semiconductor structure having a substantially layered construction, and the semiconductor device includes a channel, a current flowing in the channel substantially in parallel with layers of the semiconductor structure.
