Abstract
A power amplifier has an amplifier assembly and a resonant assembly with a resonant capacitor and a control element. A parallel resonant circuit can be formed by the resonant capacitor and a load that can be connected to the amplifier. An output voltage or an intermediate circuit voltage of the amplifier can be applied at the resonance capacitor via the control element. An NMR tomography apparatus has at least one such power amplifier. The power amplifier can be universally used with low components outlay and is able to generate a number of signal forms.
