N2 - Multilevel inverters with various pulse width modulation strategies have established their importance in high power high performance industrial applications, as they can synthesize output waveform with improved harmonic spectrum. This paper presents the performance analysis and comparison of different PWM strategies for cascaded H-bridge three-level inverter in terms of line voltage and motor current THD with their fundamental components. It is shown that harmonic loss minimized optimal-SHEPWM strategy gives better results in terms of voltage THD compared to SPWM, SVPWM and SHEPWM strategies.
