N2 - Pulse width modulation (PWM) methods significantly affect the performance of parallel NPC inverters such as efficiency, power quality, and reliability. However, in the previous research, the comparison of the PWM methods has been performed by only considering the efficiency, output current THD, and circulating current, whereas their effects on the reliability of the power devices and DC-link capacitors have not been taken into account in the analysis. In this paper, the impact of PWM methods not only on the circulating current and output current THD but also on the reliability of the power devices and DC-link capacitors of parallel NPC inverters is investigated by considering their power losses and thermal loadings.
