Abstract

As multilevel inverters are gaining importance, new topologies are being proposed especially for increased number of levels while reducing the number of power switches. In this paper, a level-doubling network (LDN) is proposed for the recently proposed `cross-connected sources based multilevel inverter (CCS-MLI)´ topology. While doubling the number of levels in the output voltage, the proposed LDN results in reduced number of power switch count in the CCS-MLI. An explanation of 11-level inverter is presented along with MATLAB/Simulink based simulation results. Experimental results are also presented so as to validate the concept.
