N2 - In this paper, a novel single-stage ac/dc converter for micro-scale wind power generation system is proposed. The power factor correction of input line currents for wind power is achieved so as to reduce the harmonic currents and decrease the noise of three-phase wind turbine. The proposed converter has both zero-voltage switching in the primary-side switches and zero-current switching in the secondary-side diodes. Compared with a traditional two-stage converter, high efficiency and high step-up voltage ratio are also accomplished in the proposed single-stage three-phase converter. In addition, the control signals are easily generated by the simple pulse width modulation (PWM) without using sinusoidal PWM. Therefore, the system cost also can be reduced. Finally, a prototype system is constructed by utilizing the controller DSP 28335. The simulation and experimental results verified the validity of the proposed converter.
