A 13 LEVEL ENVELOPE TYPE ASYMMETRIC MULTILEVEL INVERTER WITH REDUCED NUMBER OF SWITCHES.

In this paper an envelope type topology for asymmetrical MLI with less number ofswitches is proposed. This topology produces 13 levels with 10 switchesand 4 DC sources. Thefeatures of the proposed topologyarebetter quality than similar topologieswith reducedcount of semiconductors switches and DC sources. The main advantage of proposed topologyis to create a negative level without any additional circuit which reduces the voltage stress on the switches. To achieve higher levels cascade connection is also possible of this topology.The performance of the proposed topology is validated by using MATLAB Simulink simulation.
