| Abstract |
This paper proposes a new modulation strategy for multilevel inverters, which selects voltage vectors that generate zero common-mode voltage in the load, working at low switching frequency. Experimental results confirm that the method is highly effective and simple to implement in a modern microprocessor. The voltage distortion (THD), the number of commutations and the linearity are also studied. Finally, it is concluded that the proposed strategy is highly suited for inverters with a high number of levels. |
