Power Redundancy Architecture Modification for Defense Industry Applications

Not only sensors used to determine parameters such as position, orientation, and temperature in systems like unmanned aerial vehicles, automotive, aircraft, and spacecraft but also engines or reaction wheels that enable vehicles to react are critically important. Failure to power these subcomponents correctly, reading low-accuracy data, or failure to drive the engines might have catastrophic consequences. Redundancy systems are used to prevent these problems and increase reliability. Within the scope of this study, the working principles, advantages, and disadvantages of different redundancy methods are explained, and these methods are both simulated and compared. It is aimed to minimize the disadvantages by making modifications on the OR-ING circuit, which is one of these methods. Most importantly, it is argued that a redundancy circuit can be controlled by a processor, status data of the integrated circuit can be received thanks to current sensing integrated circuit and processor, input interference can be reduced, and hold-up time can be optimized by making capacitor calculations.
