A wind energy harvest system by using piezoelectric polyvinylidene fluoride (PVDF) is proposed and investigated in this research. Nozzle accelerator is designed to collect wind from environment and increase wind velocity. Using the wind induced drag force to directly blow and vibrate the PVDF employed on the subsequent duct is a simple structure of generating electricity by means of piezoelectric direct effect. Battery-support pull-up circuitry is designed to harvest very small amount of electricity from PVDF.

“…Among these, wind power generation has a comparatively simple setup. It is regarded as an effective method due to its adoption in various power systems, and multifaceted research is being conducted in order to improve power generation efficiency [2][3][4][5][6][7][8][9]. The generator in a windmill requires power generation characteristics across a wide power band because of the use of wind power as the generation method.…”

SUMMARYThis paper proposes a pole change generator for a windmill. Since micro windmill systems generate power from natural energy, power generation characteristics across a wide band are necessary. However, the conventional generator, in which the open voltage is simply proportional to the rotational velocity, encounters difficulty in generating power across a wide range of rotational velocities from low to high, because of the power generation characteristics. To develop a generator with a wide power band suitable for a micro windmill, this paper proposes a technique for switching the status of the generator coil connection. To demonstrate the effectiveness of pole changing, we use a pole-changing generator with 16 coils as an example. The coils can be connected using four patterns: 16-pole series, 8-pole 2-parallel, 4-pole 4-parallel, and 2-pole 8-parallel. Theoretical and experimental studies from this point of view demonstrate that this technique is effective.
