Traditionally electrical drives and uninterruptable power supplies generate pulse width modulated outputs. Harmonic content of such waveforms are known to cause problems. Therefore, it is worthwhile to investigate 3-phase sinus output topologies, which can compete with traditional inverter topologies, regarding performance and cost. In this paper, first some topologies for producing single-phase sinus output are reviewed. Then, the possibility of using these single-phase units for producing 3-phase output is investigated. Finally, the findings are evaluated and the course for further investigation is identified.
