초록
A novel type of single phase multi-step inverter is proposed, which has twelve-stepped levels of the output voltage. In this inverter the waveform of the output votage has smaller harmonic contents than those of a conventional six-step inverter. In this paper a new multi-step technique is analyzed. This new multi-step technique of the twelve-stewed single phase voltage source inverter has the advantage compared with the conventional six-step inverter, and the experimental results are proved by the calculation using spectrum-analyzer.
