1. An appliance for the conversion of wave energy into electrical energy, including a closed float element (1) and a bob element (2), with the bob element (2) being placed inside the float element (1) and mounted to be mobile in relation to the float element (1), with the bob element (2) being designed to be driven into relative movement in relation to the float element (1) under the action of the waves on the float element (1), characterised in that it also includes locking means (13, 50-59) designed to lock the movement of the bob element (2), and control means designed to control the locking means (13, 50-59) so as to selectively lock or release the bob element (2) in order to amplify the movement of the bob element (2) by continuously adapting the dynamic of the appliance to the waves,wherein the bob element (2) is free to rotate about a rotation axis, with the movement of the bob element (2) not being limited by a limiting device,said appliance including a power recovery device that includes a multiplicity of windings (81) positioned in a fixed manner in relation to the float element and a multiplicity of magnets (82) positioned on the bob element (2),wherein when the bob element (2) is driven in rotation in relation to the float element (1), an electric current is generated in the windings (81).
