Power conditioning requirements and trade-off considerations for the space shuttle

Avionics equipment that utilize electrical power typically convert this power by means of a converter internal to the equipment into several voltage levels. These voltages are regulated and used to power the electronic circuits within the equipment. Considering the number of electronics equipments required on the shuttle, the question arises as to whether the power converter normally supplied in each electronics equipment could be combined into a central power converter. A power distribution system would then distribute the various voltages to each load as required.
