The main objective of this activity was to study the B3R converter  and to confirm its flexibility and performance (mainly efficiency and mass reduction) versus solutions that is implemented in a satellite PCU. For details see  ESTEC SOW.
An architecture with centralised regulated bus, single battery and centralised solar array was selected for this study.
- Study, design and development of an evaluation prototype, based on the B3R topology (including protections and control loops).
- Study, design and development of an Electrical Elegant Breadboard including three power stages, based on the B3R topology (including protections and control loops).
- Laboratory tests of these converters (power stages, control loops and protections).
- Conclude the study by comparing the achieved performances (including efficiency and mass) versus current solutions implemented on a satellite PCU. Summary of the pros and cons of the use of the B3R concept.
