This is a good energy permanent magnet generator. Using a linear resource to meet the energy demand of the development. permanent generator has the advantages of simple structure, minimizing the mechanical loose On the 1.2 Wave energy conversion technologies basic mechanics model, a system of equations Up to day, different types of wave energy describing the operation of the device under linear conversion principles are illustrated, which have carefully been documented and presented as in Fig. 1 potential wave was obtained. The magnetic field in [4]. So far most researchers have concentrated on the generator was calculated by FlexPDE software. The hydrodynamic aspects of different converters. The system of movement equations was numerically two best known concepts are the IPS buoy [5] and solved with Matlab. Various calculations were the AquaBouy [6, 7]. These devices all require an performed with the different parameters of wave intermediate mechanical structure to transform the conditions and device’s structures to determine the kinetic energy of the buoy to that compatible with the device’s configuration for a 300W output power conventional turning generator, such as pump and under wave condition in the South-Central offshore turbine systems. However, the complexity in structure increases mechanical energy loss, and it is of Vietnam. The results also show potential of very hard to get the generators and related developing the wave energy
