Oscillating water column (OWC) devices and oscillating buoys (OBs) are two of the main types wave energy converters (WECs). In this paper a hybrid column-oscillating buoy converter is proposed, which we have named OWCOB. The hinged at outer wall column. As waves propagate through OWCOB, within OWC chamber moves up down, producing air flow to propel turbine. Meanwhile, oscillation OB drives sepa...

The wave energy control competition established a benchmark problem which was offered as an open challenge to the system community. had two stages: In first stage, competitors used standard simulation platform (WEC-Sim) evaluate their controllers while, in second were invited test real-time implementation on prototype tank. performance function based converted across range of sea states, but al...

A 2D numerical investigation of the power absorption a constrained wave energy hyperbaric converter (WEHC) under full-scale sea conditions is presented. fully non-linear model DualSPHysics, based on coupling smoothed particle hydrodynamics (SPH) fluid solver with multibody dynamics solver, used to interaction between and WEHC sub-systems. The was first validated against experimental data for si...

For radio frequency energy transmission, the conversion efficiency of the receiver is decisive not only for reducing sending power, but also for enabling energy transmission over long and variable distances. In this contribution, we present a passive RF-DC converter for energy harvesting at ultra-low input power at 868 MHz. The novel converter consists of a reactive matching circuit and a combi...
