This approach works for circuits with a limited number of
components, and this is why the reliability analysis of power
converters could be benefited from this method. An initial reliability
of a converter can be estimated based on the measurable
quantities such as RDS(ON), ESR, C, and so on, and it can
be updated periodically by measuring those parameters with a
regular interval. Variation of the reliability function with the
variation in RDS(ON), C, and ESR of the closed-loop boost
converter is presented in Section IV.
