Abstract

In this paper, a novel two-switch three-phase LLC resonant circuit is proposed. The proposed circuit can reduce the input harmonic current of the AC/DC interface of microscale wind turbine generator. Thus, the vibration and noise of the three-phase wind turbine can be decreased and the life span of the wind turbine can be increased. Based on the proposed converter, the primary two switches have zero-voltage switching and the secondary two diodes have zero-current switching. In addition, the three-phase power factor correction can be achieved in both transient and steady states via two-switch LLC resonant circuit without using phase-locked loop and synchronous frame d-q axis control. The maximum power point tracking of wind power system also can be achieved through the voltage control oscillator and hill climbing searching control. Finally, some experimental results are offered to verify the validity of the proposed AC/DC interface of the microscale wind turbine generation system.
