The objectives of this study are to improve the aerodynamics performance on the down-wind blade system with folding type blade which consists of the folding type rotor blade, wind vane yawing stabilizer and a bevel gearbox. The aerodynamics performance for the new wind turbine system are compared with those of the conventional up-wind blade system. In addition to, a novel multi voltage inverter system is applied for reductions of harmonic.
