摘要： A dual-point absorber includes a first buoy, a second buoy, and a power take-off. The first buoy of the dual-point absorber is connected to a linkage. The second buoy of the dual-point absorber is capable of a movement relative to the first buoy. The power take-off is coupled to the first buoy and the second buoy. The linkage can be used to reduce a heave movement of the first buoy that is caused by waves.

摘要： An electric generator driven by a source of variable energy produces at its output an alternating current (AC) output voltage and current which is converted via controllable active switching circuitry into a direct current (DC) voltage which is stored in an energy storage element. Power losses are associated with the active switching circuit and the AC to DC conversion. The power available at the output of the generator can be determined. If the available power is less than the power losses the controllable switching circuitry is disabled.

摘要： The generally up and down movement of a reaction mass is converted into rotary motion which is used to drive a rotary hydraulic spring comprised of a rotary hydraulic pump motor and an accumulator to produce a “spring” function. The invention is particularly applicable to wave energy converters (WECs) having a reaction mass which needs to be coupled to a spring to ensure its oscillation and to cause it to be centered about its center of travel. The linear up-down motion of a reaction mass may be converted via a linear-to-rotary translator to rotary motion to drive a rotary hydraulic pump/motor so as to provide spring action to the reaction mass and ensure its oscillation and proper positioning.

摘要： A wave energy converter (WEC) includes a float tending to move in phase with the waves, a spar tending to move out of phase with the float and power take off device (PTO) coupled between the float and spar for converting their relative motion into useful energy. The PTO includes a rack and pinion mechanism which drives a high-torque, multi-pole, permanent magnet generator (PMG) to produce electrical signals of relatively high frequency relative to the frequency of the waves and the basic motion of the rack and pinion mechanism. In accordance with one aspect of the invention, the rack and pinion mechanism may be located within the spar which may be hermetically sealed by a sealing mechanism which allows a thrust rod coupled between the float and spar to move up and down with little friction to ensure efficient operation. In addition, a braking arrangement is provided for inhibiting relative motion between the float and spar during extreme severe wave conditions. In this way, the pinion gears and generators need only be sized for the operational wave conditions.

摘要： A float structure for a WEC is designed to have a tapered underside to reduce the impact due to wave slam and bending moments while providing little reduction in the surface area responding to the wave surface in order to maintain the beneficial power generating capability of a “flat” float. The underside of the float presents an inverted wedge section to decrease loads associated with wave slamming. The float may have a generally toroidal or elliptical configuration at and about the “still” water line with the generally submerged underside of the float having a cross section shaped to have one or more inverted triangular sections extending between the outer perimeter of the float and its center to reduce impact loading due to wave slamming while maintaining power producing capability.

摘要： For reducing the number of anchors required for mooring a plurality of WECs in a body of water, the WECs are arrayed in two patterns enabling the sharing of anchors among the WECs. One pattern comprises pluralities of WECs disposed in polygonal shaped cells with an anchor disposed beneath each cell connected to all the WECs in the cell. A second pattern comprises a tessellated pattern of contiguous cells with WECs at the interface between contiguous pairs of cells being common to both cells of the pairs.

摘要： A damping (or heave) plate comprises a generally flat plate attached, beneath the surface of a sea, and in horizontal orientation, to a structural member subject to being vertically moved in response to passing surface waves. The plate tends to resist vertical movements and has the effect of adding mass to the structure. A vertically extending structure is added to both major surfaces of the heave plate for increasing the volume of water moved by the plate. For minimizing drag forces generally created by use of the damping plate, the vertically extending structure is shaped to include curved hydrodynamic surfaces for minimizing turbulence in the surrounding water.

摘要： The invention relates to active impedance matching systems (AIMS) and methods for increasing the efficiency of a wave energy converter (WEC) having a shaft and a shell intended to be placed in a body of water and to move relative to each other in response to forces applied to the WEC by the body of water. The system includes apparatus for: (a) extracting energy from the WEC and producing output electric energy as a function of the movement of the shell (shaft) relative to the shaft (shell): and (b) for selectively imparting energy to one of the shell and shaft for causing an increase in the displacement and velocity (or acceleration) of one of the shell and shaft relative to the other, whereby the net amount of output electrical energy produced is increased. The apparatus for extracting energy and for selectively supplying energy may be implemented using a single device capable of being operated bi-directionally, in terms of both direction and force, or may be implemented by different devices.

摘要： A power generating system comprises a bluff (non-streamlined) body placed in a fluid stream at ninety degrees to the flow direction for creating a von Karman vortex street behind the body. In the process, feedback forces are generated that excite the bluff body into oscillation. The bluff body oscillatory movements are coupled to and energize a power generator. An impedance matching system is employed for electrically varying the natural frequency characteristics of the bluff body such that, over a relatively wide range of fluid flow velocities, the bluff body oscillates at a resonant frequency of the body for maximum energy transfer from the fluid stream to the bluff body.
