The design of the STC-DBS (Satellite Television Corporation - Direct Broadcast Satellite) Electrical Power Subsystem presently under development at RCA Astro-Electronics is highlighted. To efficiently satisfy the payload power requirements, which are dominated by three 220W TWTAs, while at the same time permitting maximum use of already qualified designs, a dual bus system was selected. The payload bus, which operates during non-eclipse periods, is a shunt-regulated solar array bus at 100 volts. The housekeeping bus is regulated at 35.5 volts when sunlit and varies with the battery voltage during eclipse.
