The objective of the activity is to analyse and apply innovative power bus control schemes for geostationary missions. The aim of the new control scheme is to improve the power bus quality and reduce the size of the bus capacitor without a negative impact on the reliability of the system.
The developed control scheme is expected to lead to a significant reduction in mass for a geostationary telecom satellite power system.
A GEO power system using the control scheme developed should weigh less than a corresponding traditional S3R regulated system, while maintaining (or improving) bus quality in terms of bus ripple, load transient response and bus impedance.
It is preferred that the new control scheme does not involve major changes compared to the S3R, but uses the already installed electronics (BDRs, etc) within the PCDU.
All tasks are completed.
