Design and implementation of a new unity gain nine‐level active neutral point clamped multilevel inverter topology
View through CrossRef
The major issue with the three‐level active neutral point clamped (ANPC) inverter has been the requirement of a higher DC‐link voltage with a lower peak of the output voltage. In this study, a new unity gain ANPC multilevel inverter topology has been proposed with a lower number of switches. The proposed topology generates a nine‐level output voltage with a single DC voltage source, four capacitors, and ten switches. The two floating capacitors have a voltage rating of 0.25

which reduces the overall cost and improves the efficiency of the topology. The performance of the proposed topology has been demonstrated using various comparisons and experimental results.
