H2020 Space Information Days Status Quo of the development Generic HVPS Multi Thrust Multi Mode Modular and scalable design Power: 5 kw (TRL 5), available also as 2.5 kw Output voltage: < 500V / 1000V / 1850V / 2000V Industrialised Design Common building blocks / functional blocks Design for Manufacturing Easy & cost efficient integration Digital control Lean test appproach Studies on-going supported DLR & ESTEC & thruster suppliers QQ-T6 HEMP 3050 RIT-family (2X, 22, 10, 15) 5 kw HVPS DM 28 September 2015 13
Further future ideas Incremental developments H2020 Space Information Days Qualification and IoV of 5 kw Generic HVPS (starting by TRL 5) Two working modes: on ground and in orbit configurability Generic and modular PPU which can drive different thruster sets (for SK + OR) PPU without export regulated parts High Voltage test facilities for high power PPUs Generic test equipment Generic HV connectors and cable for easy AIT 28 September 2015 14
Further future ideas Advanced concepts H2020 Space Information Days Direct drive System level studies including solar generator, PCDU and PPU Merge PPU functions and PCDU Modular concept Instead of single PPU self standing modules assembled on satellite Space Tug and multimission concepts PPU for specific needs (e.g. demanding radiation environment, high power ) Remark: FCU, Neutralizer should be generic. This would simplify generic PPU approach 28 September 2015 15
