Power is then transferred from the nonrotating member to the rotating member of the rotary joint through slip rings and brushes. On the rotating member, power is conducted through switch gears to dc/dc converters which output the six primary voltages required by the klystrons. Each voltage is conducted to a summing bus through a switch gear. Subsequently, each voltage is conducted from the summing buses to the 142,902 klystrons. Attitude control and stationkeeping Trade studies indicated the desirability of a simple ACSS employing high-
