Design for Reliability: The origin of aging and degradation in advanced power modules and emerging state of health (SOH) estimation techniques

Not all components in a power converter circuit are equally impacted by aging, and there exist module or component level precursor and diagnostics, which are mostly electrical characterization. This presentation will reveal the origin of aging and corresponding degradation in electrical and thermal performance associated with power modules and other circuit components. In addition to offline measurements, several emerging online state of health (SOH) estimation techniques applicable to active devices such as MOSFETs and IGBTS, and passive components will be discussed during this seminar. The origin of degradation in a live circuit as well as how to determine the remaining life of a power converter using the concept of dynamic safe operating area (DSOA) will be presented. These offline and online techniques will finally be linked to build more robust power modules and converters.
