저가의 SMR회로를 이용한 소형풍력발전의 센서리스 fuzzy MPPT제어

초록

This paper proposes a cost-efficiency Switched-Mode Rectifier(SMR) with sensorless fuzzy Maximum Power Point Tracking(MPPT) control in Wind Power Generation System(WPGS). The high synchronous impedance of the PMSG with the SMR can act as an inductor of a boost converter, so that the SMR with the impedance of the PMSG can replace the conventional boost converter. The sensorless MPPT control is controlled by changing the duty-ratio of the SMR. The relation of the generating power to the duty-ratio is applied by chain rule. Computer simulations of the total system verifying the proposed concepts are presented.
