Each subarray having a high klystron density (30-42) would be serviced by one distribution point (see Figure IV-C-6-5a). Table IV-C-6-1 shows the klystron density in each area of the antenna. IV-C-6-5 POWER SYSTEM REGULATION The klystrons require sane magnitude of power supply regulation in order to function properly. On which side of the Solar Array/Microwave antenna interface the power supply regulation takes place should be the result of a tradeoff. Another tradeoff roust be made on the merits of an extremely precise power supply regulator versus a klystron which will function properly over a large power range. The usual parameters of design complexity, cost, weight, and power consumption must be considered. Assuming the power supply regulation takes place in the microwave antenna, then in order to avoid single point failures several power supply regulators must be used in the distribution circuit. It seems reasonable that the regulator should be included in the switch gear assemblies, so a failure of a power supply regulator would only affect 1/16th of the antenna electrical power.
