Power recovery from data line in avionic applications

In this paper, we propose a novel power recovery approach to reduce the mass of the cables installed in aircrafts. The power recovery unit harvests energy from data field bus which is recently presented to modify classical Avionics Full Duplex Ethernet (AFDX) networks, to power up the Smart Sensor Interface (SSI) module entirely. A top-down modeling approach in Verilog-A is used to build complex modules in the Power Conversion Chain (PCC) which makes power transfer and distribution possible. The effects of frequency and the size of capacitor reservoir on settling time and output voltage ripple are studied. Simulation results in system level prove that the proposed power recovery scheme could procure and deliver significant amount of power to SSI which makes the structure self-powered and therefore additional power lines are saved.
