Plastic optical fiber-based wiring solution for automotive power electronics systems

Abstract

Power electronics systems represent a fundamental technology in modern electric vehicles and also in many industrial applications. In this context, the presence of high electromagnetic interferences due to high dv/dt variations make it preferable to use polymer optical fibers (POFs) to connect the controller-to-converter digital signals, thus minimizing unwanted control actions. The authors have introduced successfuly a POF-based solution in an automotive grade back-to-back multiphase electric drive test bench. In addition, a number of points for improvement have been identified and will be presented.
