To supplement or as an adjunct to any overall testing program, various analyses should be performed. These analyses verify that all piece parts are properly applied and that the customer’s overall expectations for reliability will be achieved.

Analysis proves that the space power supply meets its requirements. Although many aspects of the space power supply’s design are best characterized by testing, some areas also demand substantiation by analysis, which establishes the design margins. In the development of a space power supply, the most frequently required analyses are circuit (SPICE), electrical stress, thermal, derating, worse case, MTBF, FMECA, EMI, environmental and radiation effects. There is a hierarchy to these analyses, and just like in college courses, many have prerequisites.
