Abstract
In this paper, a new submultilevel converter (SMC) is introduced first. Then, the cascaded structure based on the series connection of proposed SMCs is presented. The proposed cascade topology can generate all possible levels at output voltage waveform. In order to show the advantages of the presented topology, the comparison results with recently proposed multilevel converters are provided. According to the comparison results, it is indicated that the proposed structure requires the least number of power switches and dc sources. Also, the total blocked voltage by the switches and power losses of the proposed cascade topology is less than other topologies. The presented topology can be used in high-voltage applications. In order to verify the performance of the presented topology, the experimental and simulation works are provided.
