SMALL-SCALE WIND POWER GENERATION DEVICE AND METHOD USING A SWITCHED-MODE RECTIFIER(SMR) WITH SENSORLESS MAXIMUM POWER POINT TRACKING(MPPT)

摘要

A small scale wind power generating apparatus and a method thereof which is combined with a switch mode rectifier and control of a sensorless maximum power point tracking are disclosed. The present invention comprises a diode rectifier which receives alternating currents from three phases; a switch connected to both ends of the diode rectifier; a converter unit having a diode of which anode is connected to one end of the switch and a capacitor of which one end is connected to a cathode of the diode whereas another end is connected to another end of the switch; and a control unit adjusting a duty ratio of the switch based on the difference between the current power of a permanent magnetic synchronous generator and the previous power of the permanent magnetic synchronous generator.
