A general methodology is applied to calculate the reliability of NPC inverter with most commonly used control strategies The mean time to failure (MTTF) of NPC inverter is derived for different control strategies The failure rate of components that is relevant to this study and junction temperature calculation is developed Experimental results obtained have promptly justified the theoretical analysis and outlined procedure.
