Power losses are the most critical metrics in power converters analysis and has a significant impact on economic and technological assessments due to its sufficient approximation. This article aims to prove that the power losses (Switching & Conduction losses) are very low in low frequency switching modulation in contrast with high switching frequency modulation. Two switching modulation techniques Phase Disposition (PD-multi carrier-based pulse width modulation at high switching frequency) and Selective Harmonic Elimination Pulse Width Modulation (SHEPWM-fundamental switching frequency) are considered for the power loss assessment in 15-level reduced switch asymmetric multi-level inverter. This work proposed a simplified model for calculation of switching losses in multilevel inverters using MATAB SIMULINK. Further, the thermal model of the proposed inverter is implemented on PLECS for analyzing the power losses. The comparative analysis of switching and conduction losses of the proposed inverter with the PLECS thermal model and MATLAB precise models are integral part of this research.
