Abstract
This paper presents the optimized conditions for stepped wave inverters in order to minimize the total harmonic distortion present in the output waveform. It is shown that one- and two-level waveforms do not have sufficient degrees of freedom to meet harmonic standards like the IEEE 519. However three-level waveforms can be constructed, which meet such power quality standards and as a result, do not require output filtering.
