A novel asymmetrical 13-Level inverter topology is proposed for high-power AC motor drives requiring a medium voltage inverter. The proposed topology, which is composed of two T-Type inverters connected through additional power switches, can generate a high fundamental frequency output voltage using a low switching frequency, thus achieving high efficiency and high-power quality, but with complexity and costs comparable or better than those of equivalent basic multilevel inverter topologies.

Abstract
A novel asymmetrical 13-Level inverter topology is proposed for high-power AC motor drives requiring a medium voltage inverter. The proposed topology, which is composed of two T-Type inverters connected through additional power switches, can generate a high fundamental frequency output voltage using a low switching frequency, thus achieving high efficiency and high-power quality, but with complexity and costs comparable or better than those of equivalent basic multilevel inverter topologies.File in questo prodotto:
