The rationale behind, and a proposed approach for, application of government assistance to accelerate the process of moving a new electric vehicle propulsion system product from technological readiness to profitable marketplace acceptance and utilization are described. Emphasis is on strategy, applicable incentives, and an implementation process.
A power processing system (PPS) for a communication satellite, high power (200W RF) multi-stage depressed collector, 12 GHz, traveling wave tube, is described. The PPS converts spacecraft bus power at a nominal voltage of 76 Vdc to the levels necessary for operating a ten-collector coupled cavity TWT requiring approximately 500 watts of input power. Regulated voltages of up to -11.3K Vdc are provided along with command, protection and telemetry signal conditioning circuits. Power processor interface requirements are set forth and a block diagram illustrating the basic approach utilized is presented. Overall performance, design characteristics and unique features are discussed. Thermal and mechanical interface requirements impacting on PPS design are described as well as the thermal control technique utilized for the overall PPS/TWT assembly.
