Design of 17-Level Inverter with Reduced Switch Count

Abstract

Multilevel inverters (MLIs) are unique in that they produce a voltage waveform that is a better staircase copy of a sinusoidal waveform, which makes in this paper, we discuss a 17-level asymmetric single-phase MLI with asymmetrical DC sources and no H-bridge, the proposed architecture is useful for grid-connected MLI for solar PV applications which provides up to 17 levels of output voltage. In order to explain the proposed topological modes of operation, diagrams and a switching table are used Because of this, this architecture reduces the number of components, the price of the system and its size. The 17-level MLIs' cost function (CF), total standing voltage (TSV), power loss, and efficiency are all studied. The suggested MLI architecture is compared to numerous previously reported cost-effective topologies using a cost function derived from total standing voltage. On the right side of the page, you'll find visual representations of several parameters, along the proposed MLI is incompatible with the TSV and component specifications. According to IEEE standards, Total Harmonic Distortion (THD) is done in MATLAB/Simulink is required to verify the proposed design, which also displays simulated output voltage and current waveforms.
