Abstract—Today reliability is one of the serious requirements
of electronic systems. The numbers of system failures, repair
cost, guarantee, etc are estimated by reliability estimation. In
this paper, the reliability of a switching power supply, which is
used for personal computers, evaluates. It will show that the
most of failure rates depends on power circuit because of more
stresses and dissipations. Derating effect of devices on the
failure rate will discuss. Part stress count utilizes for failure rate
calculations and a prototype’s waveforms uses for stress
detection and calculation of dissipations.
Index Terms—Failure rate, reliability, SMPS, PC.
