Abstract
A power electronic circuit arrangement which comprises a first power converter is specified. A second power converter is connected between the load terminals of the first power converter and a load. The negative or positive values of the DC voltage intermediate circuits of the first and second power converters can be added by means of corresponding driving of the power converters. This achieves finer voltage gradation and, consequently, an improved approximation of the resulting output voltage to the sinusoidal waveform.
