VI. CONCLUSION AND FUTURE WORK
Reliability degradation of a boost converter being operated
in closed loop has been presented in this paper. Components
used in this converter exhibit parameter variations due to aging
of the entire converter. Therefore, the effect of any variation in
MOSFET ON-state resistance RDS(ON), capacitance C, and
ESR of the output capacitor on the reliability of the power
converter have been analyzed, and a summary is presented in
Table III. The MTTF of the closed-loop converter decreases
with the gradual increase in both RDS(ON) and ESR. However,
any variation in RDS(ON) significantly impacts the reliability of
the entire converter compared with Cand ESR. In addition, the
reliability of the converter varies in a more complex manner
