The present invention provides a method of controlling a power conversion apparatus, which is capable of solving the instability of a VL control system caused by load variation of a power converter. A voltage (VL) 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 (ks**) 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 (ks**) decreases as an amplitude (Im) of an alternating current outputted from the power converter becomes larger, to generate a second voltage control rate command (ks*). A switching signal which is generated on the basis of the second voltage control rate command (ks*) is given to the power converter. |
