A Transient Protection Device is proposed in order to decrease the sensitivity of avionics to power bus transients. The device utilizes an array of ultra-capacitors for energy storage in order to provide a local power buffer to isolate vehicle loads from interruptions of the main power bus. In addition to energy storage, a set of electronics is included in the design to facilitate the integration of the energy storage devices with the existing power bus and vehicle load interfaces. These electronics limit the maximum current drawn by both the Transient Protection Device and downstream loads, control the rise time of the power supply provided to downstream loads, and provide input and output filtering to ensure compatibility with vehicle Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) requirements. In addition to the development of a design for the energy storage and interface electronics, a set of prototype hardware will be manufactured to support a test with a simulated power bus configuration to demonstrate the efficacy of the concept at mitigating an upstream disruption to a downstream load.
