Design of DPU and PSU for ESA JUICE SWI instrument

Abstract - The objective of this paper is to present a design of Data Processing Unit (DPU) and Power Supply Subsystem (PSU) that are designed in the frame of SWI instrument developed for ESA JUICE L-class mission. The DPU is a main controller of the instrument, providing a communication link with the spacecraft and several interfaces towards subsystems. The PSU consists of three units: Switch and House Keeping, BIAS and DCDC. The presented concept based on the design presented for the subsystems and instrument CDRs.
