Modern day electrification of the transport sector gives new challengens to the electric infrastructure. At the same time, electric energy storage on board vehicles and ships allow for new convenient and efficient solutions for charging and interaction with grids. Inductive power transfer (IPT) is a...

Purpose The goal of this paper is to quantify the impact of the constraints of the power take-off system (PTO) on the power extraction of a point absorber wave energy converter (WEC). Such constraints include power, torque and maximum stroke limitations. Two different concepts, unidirectional and...
