Abstract:
1. A combination comprising: a wave energy converter (WEC) having two elements intended to be placed in a body of water, the two elements being able to move relative to each other in response to forces applied to the WEC by the body of water; at least one of the two elements being a wave energy absorber; and means connected between the two elements for extracting energy from the WEC and for producing output electric energy as a function of the relative movement between the two elements; and means connected between a source of energy and one of the two elements for sensing and determining selected ones of the displacement, velocity and acceleration of one of two elements relative to the other for selectively and actively supplying energy to one of the two elements for causing an increase in the displacement and velocity of one of the two elements relative to the other, whereby the net amount of output electrical energy produced is increased.
