Abstract
An inverter arrangement which comprises two inverter units which comprise an intermediate voltage circuit and phase-specific switch components. The inverter arrangement also comprises phase-specific one-phase autotransformers, the first poles of which are connected to the phase-specific outputs of the first inverter unit and the second poles to the phase-specific outputs of the second inverter unit, and thus the output voltage of the inverter is obtained from the third poles of the autotransformers.
