A Novel Single-Phase Multilevel Inverter Topology with Reduced Component Count

Multilevel inverter has developed as a superior elective for different applications (medium and also high power) meeting the standards. When compared with the basic 2-level voltage source inverters, the multilevel inverter has been found superior due to reduced electromagnetic compatibility and lesser harmonic distortion. In this paper, a novel multilevel inverter, which uses fewer numbers of total components as compared with the existing inverters (especially for higher levels), has been suggested. Hence, the total cost is reduced and complexity is also reduced for higher voltage levels. The comparison has been done regarding number of DC sources, switches, and diodes. The topology is simulated for 19-level employing SPWM as the control strategy, being simulated in MATLAB/SIMULINK environment and validated this simulation by using real-time digital simulator (OP-5600).
