Abstract
A power amplifier has a supply assembly for offering an intermediate circuit voltage and an output stage connected to the supply assembly for generating an output voltage from the intermediate circuit voltage. The supply assembly contains at least two voltage sources that can be optionally connected in parallel or in series via at least one switch stage. A nuclear magnetic resonance tomography apparatus can be equipped with such a power amplifier. The power amplifier exhibits the required high performance capability in quantitative and qualitative terms, with low losses.
