Modeling and dynamic performance analysis of a high power density tubular linear switch reluctance generator for direct drive marine wave energy conversion

Marine wave energy is characterized by high power density and worldwide distribution thus an important renewable source energy. A high power density tubular linear switch reluctance generator (TLSRG) is presented in this paper to be used as the direct drive wave energy generator. The mover of the machine includes series of ring segments which are insulated magnetically. The topology and detailed structure of the presented machine are demonstrated. The transient FEM model with the power converter circuit for generator mode is developed and the dynamic performance of the presented TLSRG are given, validating that the presented TLSRG has been an good candidate for wave energy generator.
