| Abstract: | The multi-level inverter (MLI) plays an emergent role in high and medium-power applications. Due to the numerous advantages like lower power loss, switching loss and harmonics, the MLI is used in various applications. The major drawbacks of MLI are a higher number of switches and complex modulation strategies, thus increasing the voltage stress. Therefore, this paper proposed a novel single-phase cascaded 51-level inverter topology with fewer switches and DC sources to improve system performance. In this proposed topology, 8 IGBT switches along with 2 DC voltage sources are considered for producing 51 levels of voltage. This 51-level inverter is tuned with the help of an EPDB controller, which is a combination of Emperor Penguin Optimization (EPO) and Deep Belief Network (DBN). The EPO is used to optimize the DBN procedure to handle the MLI switches easily. Thus, it generates low harmonics voltage and error-free output voltage. The proposed inverter topology is compared with existing inverter topologies regarding the number of voltage sources, switches, and total harmonics distortion (THD). The comparative analysis demonstrates that the suggested inverter topology provides higher voltages, thereby reducing the THD of voltage to 1.17% and current to 0.10%, which are relatively lower than the existing inverter topologies; moreover, the efficiency of the proposed converter is 99.18%.
