This paper introduces two enhanced pulse width modulation (PWM) techniques, Enhanced Level Shifted PWM (ELS-PWM) and Enhanced Phase Shifted PWM (EPS-PWM), for cascaded five-level neutral point clamped (NPC) H-Bridge configurations in multilevel inverters (MLIs). These methods aim to address issues such as unequal power losses, junction temperature disparities, and reduced efficiency in traditional PWM techniques. The proposed techniques utilize modified modulating waves and restructured triangular waves to improve power quality, balance power distribution, and ensure uniform power allocation across inverter legs. The results show identical switch utilization rates, reduced switching times, lower junction temperatures, and enhanced overall efficiency of the FLNPCHC-MLI. The methods were validated through MATLAB simulations and tested using a 1 kVA laboratory prototype. The outcomes demonstrate significant improvements in total harmonic distortion (reduced to approximately 2.3%) and efficiency (increased to approximately 97.8%), offering a promising solution for high-voltage applications. The paper also discusses the applications and future scope of these techniques in various power electronic systems.This paper introduces two enhanced pulse width modulation (PWM) techniques, Enhanced Level Shifted PWM (ELS-PWM) and Enhanced Phase Shifted PWM (EPS-PWM), for cascaded five-level neutral point clamped (NPC) H-Bridge configurations in multilevel inverters (MLIs).
