In the wave energy conversion, the use of linear generator has earlier been regarded as difficult and uneconomical. Many attempts have been spent to overcome difficulties [15-17] however, for real field application, there are still many problems. In this study, an attempt to improve the magnetic flux density in linear generator has been investigated. A dual Halbach array structure is investigated on parameters of line generator in wave energy converter to enhance flux density in air gap, thus to improve output performance of linear machine. Numerical result from finite element method is employed to simulate and observe the flux distribution in the machine. The result also shows that the double Halbach array has increased magnetic flux density compared to the schema used in linear generator of Direct driven wave energy conversion. date: 2018-10-27 date_type: published full_text_status: public pres_type: paper pagerange: 430-436 event_title: International Conference on Fluid Machinery and Automation Systems (ICFMAS) event_dates: 2018 event_type: conference refereed: TRUE citation: Do, Huy Diep and Dang, The Ba and Nguyen, Van Duc (2018) Investigate magnetic field of dual Halbach array in linear generator using for wave energy conversion.
