电力转换装置的控制方法

Method of controlling power conversion apparatus
Abstract:
A voltage of a reactor is detected. a correction is made on the basis of the voltage of the reactor so that a first voltage control rate command which is a ratio of an amplitude of an AC voltage to an average value of a DC voltage increases as a harmonic component of the DC voltage becomes higher and the first voltage control rate command decreases as an amplitude of an alternating current outputted from the power converter becomes larger, to generate a second voltage control rate command. A switching signal which is generated on the basis of the second voltage control rate command is given to the power converter.
