Abstract This article presents an innovative asymmetric multilevel inverter (MLI) topology that outperforms conventional counterparts. The introduced a breakthrough in implementing power electronics control by maximizing specific levels while minimizing switching components. A cutting-edge scheme for optimal operation of the cascaded half-bridge MLI is presented. ant lion optimization (ALO) algorithm was implemented to optimize reduce total harmonic distortion (THD) and improve quality. For verification, performance effectiveness ALO technique are assessed comparing its results those obtained using simplified sinusoidal pulse width modulation (SSPWM) technique, genetic (GA), particle swarm (PSO) existing literature. Simulation verified efficacy finding parameters. suggested method showcases remarkable reduction THD compared SSPWM. quality resulting waveform enhanced, both filter size cost were significantly reduced. To meet stringent IEEE standards, LC has been designed with minimal proper requirements. Experimental validation scheme, dSPACE R&D controller board unequivocally, confirmed robustness effectiveness. groundbreaking study not only introduces superior but also validates exceptional through comprehensive analysis experimentation. experimental waveforms showed good matching simulation outcomes. findings hold immense promise advancing field system revolutionizing designing implementation efficient cost-effective systems.
