Inspecting Impact of Cabling Infrastructure on Reflected wave and EMI for More Electric Aircraft (MEA) motor drives

Aircraft industry is seeing a paradigm shift towards more electric-based operation, increasing requirements for electrical wiring systems exponentially in terms of frequency and voltage stress. Traditionally, aircraft power transmission cables are unshielded and placed close to ground plane and communication infrastructures. These demand rethinking of aircraft standards viz DO-160G and different cable interconnection systems. This paper investigates various cable options to handle the increased load demand and its impact on electromagnetic interactions and reflected wave phenomenon. It was noted that separately shielded cable generates 59% less common-mode noise generation but aids in 23% higher reflected wave overvoltage as opposed to unshielded cable configuration.
