Alternative Lightning Protection Solutions for an Airborne Embedded Controller
Our sponsor, Collins Aerospace has assigned us to come up with alternative solutions for lightning protection for an airborne controller. Our team reviewed possible alternative solutions including galvanic isolation methods to break lightning current loops, reducing TVS size and quantity, and considering the failure modes to ensure that loss of lightning suppression capability cannot fail undetectably. From the potential solutions, we determined that constructing a galvanic isolated circuit using SPI (serial Peripheral Interface) bus system to break the lightning current loop would be the most effective solution. Our main goal for this project was build a working prototype of TVS circuit on PCB (printed circuit board). To test the PCB, we will introduce the lightning simulation and test check the whole process with Raspberry Pi 3.
