Worse Case Analysis

Worse case analysis assesses the ability of the space power supply to meet its requirements after the effects of tolerance, temperature, aging and radiation.This analysis starts with the establishment of a parts data base which takes all these factors into account.

Each pertinent circuit area is then examined, with the assistance if the SPICE model, for performance. Either a root-sum-squares (RSS) or extreme value analysis (EVA) may be performed, depending on the requirements and the correlation between the component input variables.
