Performing a detailed design review of a power supply involves an understanding of Reliability Physics which leverages the knowledge and understanding of the processes and mechanisms that induce failure to predict reliability and improve product performance. Ensuring this reliability is becoming increasingly difficult due to the increasing complexity of electronic circuits, increasing power requirements, new component and material technologies including the introduction of less robust components.

Power supplies struggle with reliability because they are often cost, space and schedule constrained. Typically, power supplies are looked at as a necessary evil, get the space leftover after the processor and memory are configured, and because the power supply requirements are often not known until the last minute when the analog/digital circuitry is designed.

Power supplies are manufactured with both SMT and Through-Hole components, utilize heatsinks for high power, and often have to perform at high voltage/high current levels. Custom magnetics, e.g. transformers, must handle transients, electrical noise, temperature variation as well as meet the requirements of IEC-61000-4-X and FCC/CISPR EMC requirements.

This webinar will address these design issues, offer solutions or methods for mitigation in addition to a testing approach to reduce reliability issues.
