Optimal Design of New Cascaded Switch-Ladder Multilevel Inverter Structure
TLDR
A new cascade switch-ladder multilevel inverter topology is presented which can generate a large number of output voltage levels and requires fewer numbers of components than other structures.Abstract:
In this paper, a new cascade switch-ladder multilevel inverter topology is presented which can generate a large number of output voltage levels. First, a fundamental switch-ladder multilevel inverter structure is described. Then, the structure of recommended cascade topology based on series connection of fundamental switch-ladder topologies is presented. To generate maximum number of levels with minimum number of switching elements, dc sources, and voltage on switches, the proposed cascade topology is optimized. Comparison results prove that the presented cascade topology requires fewer numbers of components. Also, the value of voltage rating on switches is less than other structures. Experimental results for two topologies are analyzed to verify the performance of the proposed topology.read more
