Abstract
An airflow generator power supply of an embodiment supplies alternating-current voltage to a plurality of airflow generators on a blade of a wind turbine generator. The power supply has a frequency converter, a plurality of transformers, and a switch. The frequency converter generates alternating-current voltage. Each transformer amplifies the alternating-current voltage and applies the amplified voltage to the corresponding airflow generator. The switch outputs the alternating-current voltage from the frequency converter to one selected from the transformers.
