Abstract: The paper provides an overview of linear generator development and testing experience of three different prototype solutions applicable for small-scale wave energy converters. The research was focused on wave power utilization in the Baltic Sea – basin of relatively low wave energy conditions. Developed technical solutions have been tested for their applicability and efficiency in small scale pilot cases. The presented concepts are based on developed linear generator. The unique arrangement of the pairs of permanent magnets and ferromagnetic cores between them was used in order to achieve better inductive properties of a magnetic field and as result, fewer materials were used and more electric power was generated. The developed engine was assessed against three concepts: (1) engine embedded in the stand-alone device in an almost water isolated floating carrier; (2) attached to a Single Point Mooring Buoy providing an additional source of energy for marine navigation signs; and (3) attached to the sea-wards looking pier in order to provide an illumination. Newly developed technical concept, such as a small-scale, versatile, low-cost and high capacity linear generator, and proposed installation solutions may open opportunities for wave energy utilization also in the regions of low wave energy such as the Baltic Sea.
