Abstract
A microwave tube system for use with a spacecraft telecommunication system is provided. The system includes a traveling wave tube subsystem, a high voltage converter subsystem, and a low voltage converter subsystem. The traveling wave tube subsystem includes a plurality of traveling wave tubes. The high voltage converter subsystem powers the traveling wave tube subsystem. The high voltage converter subsystem includes a plurality of high voltage converter members that are paired with the traveling wave tubes on a one-to-one basis. The low voltage converter subsystem is a central power conditioner subsystem including a plurality of low voltage power conditioners that are connected in parallel to one another. A common power output of the central power conditioner subsystem is received by the high voltage converter members which in turn power the traveling wave tubes that are paired with the high voltage converters. Such configured central power conditioner subsystem requires less circuitry and fewer low voltage power conditioners thereby resulting in lower spacecraft weight and volume.
