In this paper we present a low cost fault-tolerant attitude determination system to a scientific satellite using COTS devices. We related our experience in developing the attitude determination system, where we combine proven fault tolerance techniques to protect the whole system composed only by COTS from the effects produced by transient faults. We detailed the failure cases and the detection, reconfiguration...
This paper presents a methodology for integrating reliability considerations into the performance analysis carried out during the design of fault-tolerant power converters. The methodology relies on using a state-space representation of the power converter, based on averaging, similar to the ones used when analyzing linear time-invariant systems, and assumes an unknown-but-bounded uncertainty model...
This paper analyzes the maximal power loss in the output diode of flyback switching converter operating in both continuous conducting mode (CCM) and discontinuous conducting mode (DCM). Comparing with the previous work, this paper extends the condition, under which the maximal power loss of the output diode occurs, from the CCM to the DCM. Three correlative tasks are included. Firstly, through an...
