Avionic Dual Redundant Power Supply System - Fault Demo

Datsen Davies Tharakan

Introduction:
The design portrays general architecture of avionic dual redundant power supply system. The design example illustrates the Fault Analyzer and Experiment Analyzer features in SaberRD that can simulate multiple faults in a single simulation. Whereas conventional way of injecting faults at schematic level requires number of simulations for multiple faults. A comparison between fault injection using fault analyzer and conventional method is explained in the design example.
Faults are injected at primary main bus, generator and relay coil using Fault Analyzer. Design is then tested to verify whether the system satisfies all the design objectives. Using experiment report feature, users can verify the test conditions in a glance.
