Description
Robust Power Management Circuits for Harsh Space Environments
CONAN IC has been designed in the framework of ARTES ESA program by a consortium composed of Airbus Defence and Space, which has specified the requirement for this electronic circuit breaker, and Weeroc which has designed the CONAN IC. Telecom Satellite Power Control and Distribution Units (PCDUs) in particular and most satellite PCDUs in general still use fuses as circuit breaker. Having a...
Abstract
In this paper we present the design and applications of a new rad-hard quad power switch that emulates fuse load shedding characteristics (i.e. shorter load shedding time for higher currents with a slow shedding time close to the load rating current). The fuse type load shedding time, also called $i^2t$ type characteristic, corresponds to a fixed amount of dissipated...
This talk aims at presenting the results from several programs
SloGaN VLAIO project (Flemish regional funding)
GAN-IC4S ESA GTSP program
EleGaNt European Commission H2020 Space work program
GaN Half-bridges were developed and tested. The aim was to achieve integration of high voltage & high current transistors with low voltage control & gate drive devices.
The PROMISE Design Standard and Library is currently being used (and expanded) to develop a very high efficiency, low voltage, high current DC-DC power converter, based on a novel architecture of control, which allows it to be flexible and reconfigurable as a function of application and fault tolerance requirements. This Scalable power source controller IC ( SCOPS) is targeted for use in space...
Thales Alenia Space has partnered with MinDCet (IC design house) in an ESA program for the development of a single chip dc-dc controller. The IC design was done on SOI and high voltage process.
Controller run2, was developed & tapped-out in development under an ESA GSTP program. Formal qualification for Space is reaching its end. The component Plastic BGA has now been successfully included...
This paper describes work on the characterisation of a Low voltage \high current DC DC converter for space applications
