Summary: | This paper presents a compact and configurable DC/DC converter able to generate several isolated output voltages starting from 28V or 50V input bus voltage and conceived to be used mainly as power supply of spacecraft payloads/instruments of ESA missions. The DC-DC converter has been designed to be both compact and configurable, in order to comply with different needs. The idea is to make the design of such converter available together with a complete list of the well-known qualified parts, a board layout and all the necessary analysis like WCA, FMECA, PSA, reliability and radiation analysis. In this way the end-user is fully aware of the implementation and limitations of the power supply. Since one of the main requirement of a Power supply is the compactness, the effort of the project has been mainly devoted to reduce the size and the mass of the converter. For this purpose, a dedicated ASIC has been developed in order to integrate inside a single chip multiple functions, including protections, and avoiding any failure propagation outside the module. |
