In order to improve the level of integration and at the same time optimize efficiency and thermal management, the adopted architecture implements 3 key points: high switching frequency, Gallium Nitride (GaN) switches [1] and planar transformer [2] which allow to reduce the mass/volume and to reach high efficiency and a very high integration capability. The size of the converter is further reduced by means of the use of digital control [4] which offers many advantages including simplification of the power management, easy adjustment of sequencing and soft start function, rejection of input/output transients and reduction of the parts count. The delivery rate and the reduction of the recurring cost play a key role in the new space market, for this reason only SMT parts have been selected which allow strongly reducing manufacturing, assembly, integration and test (MAIT) time/costs. Thanks to the new concept a mass reduction of 50% (compared to the classical Silicon MOSFET based architecture) is achieved. The proposed solution reaches a power density in the range of 2kW/kg. Electric Propulsion (EP) is the typical application for such HVPS [5]. In this frame a prototype 1.2kV/1.2kW has been developed.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"15 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79049656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spacecraft will orbit the sun in a moderately elliptical orbit. It will, amongst other things, investigate the near sun heliosphere environment and its magnetized atmosphere by using in-situ measurements very close to the sun to improve our understanding of solar and heliospheric processes. The Solar Orbiter spacecraft will approach the sun close to 0.28 AU. While the Solar Orbiter solar array design is, to a large extent, based on the design of the BepiColombo Mercury Planetary Orbiter solar array, the thermal shields and rear side foil is very specific for this mission. Solar Orbiter is equipped with unique and highly sensitive remote-sensing and in-situ sensors which require limiting the radiated electromagnetic emission. Additionally, the mission requires that optical and thermal reflections to the spacecraft are minimized. Some solar array heat shields have to withstand temperatures of more than 450°C, whereas others are designed such that the temperature is below 270°C to keep the structures within their qualified temperature range and simultaneously fulfil sunlight reflection requirements. This paper describes the Solar Orbiter solar array design in general and the thermal shield design in detail with its challenges to cope both the thermal and stray light requirements.","PeriodicalId":6734,"journal":{"name":"2019 European Space Power Conference (ESPC)","volume":"24 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79190744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
