A wind power generator is one of the clean energy sources. Since the output power increases proportionally to the third power of the wind velocity, a diffuser-type wind turbine has been known to increase the output power. Then, a study for increasing the output power of a micro-wind generator was performed. It is shown that novel diffuser structure (a cylindrical shroud) that can provide wind energy to blades effectively. The shroud was designed on the basis of an electronic computer analysis as well as experiment. The generation test with a truck running at a speed of 40-60km/h proves that the generator with shroud can provide higher output power than that without shroud. Based on the analysis, another diffuser structure (a compound shroud) was designed to reduce cost to manufacture the cylindrical shroud. The generation test was done with a test machine and preliminary result was reported.
