Surveyor Television Power Conditioning

Electronic equipment in the Surveyor spacecraft is required to operate in three widely differing environments: the launch and boost phase, the transit between earth and moon and the lunar surface. Because of the wide range of lunar temperatures, the equipment must survive both cryogenic temperatures and severe heat exposure. The weight of the electronic assemblies is tightly limited by the weight budget of the spacecraft. The television power-conditioner unit contains examples of solutions to the design problems. Solid-state power conditioning circuits perform the general function of transforming spacecraft bus voltage to the various voltage forms required for camera operation. The circuit design, packaging and production techniques, and the performance characteristics are described to illustrate a typical example of Surveyor spacecraft hardware.
