N2  - This paper presents the design optimization of linear permanent magnet (PM) generator for wave energy conversion using finite element method (FEM). A linear PM generator with triangular-shaped magnet is proposed, which has higher electromagnetic characteristics, superior performance and low weight as compared to conventional linear PM generator with rectangularshaped magnet. The Individual Parameter (IP) optimization technique is employed in order to optimize and achieve optimum performance of linear PM generator. The objective function, optimization variables; magnet angle, Mθ(Î?)(θ), the pole-width ratio, Pw ratio (Ï?p/Ï?mz), and split ratio between translator and stator, Sa ratio (Rm/Re), and constraints are defined. The efficiency and its main parts; copper and iron loss are computed using time-stepping FEM. The optimal values after optimization are presented which yields highest efficiency. © JES 2016 on-line : journal/esrgroups.org/jes.
