Design, implementation, and analysis of an asymmetrically configured DK-type multilevel inverter
ABSTRACT This work proposes a new configuration of asymmetrical MLI which is called a dual kite type (DK-type) multilevel inverter. Its special features include the low total standing voltage (TSV) along with less number of total components. The basic module of the proposed structure is able to generate 15 levels without the use of h-bridge. This results in decreasing the voltage stress considerably. The extension of the proposed circuit can be done in order to increase the levels. The operation of proposed MLI has been discussed in detail, and its comparison with some recently proposed topologies has been done in the paper. Moreover, the simulation results for different constant and dynamic loading conditions have been presented and experimental verification of the same has been done and results have been shown. Fundamental frequency-based switching strategy, also called nearest level control (NLC) modulation technique, is used for providing the switching signals. Further, loss evaluation in the proposed structure has been completed with the help of PLECS software. 5.5% THD is present in the output voltage. The proposed MLI has the maximum efficiency of 98.68% at the output power level of 0.5 kW. The results and analysis presented in the paper describe the improved performance of the proposed MLI.
