Change in Capacitance (C)
The effect of capacitance variation on the reliability and the
MTTF of the converter is discussed in this section. The output
capacitance of the converter was varied from 10 to 5 μF in steps
of 1 μF. RDS(ON) and ESR were set to 34 mΩ and 0.1 Ω,
respectively. The failure of an aluminum electrolytic capacitor
is shown in (13) as follows:
