Abstract
A power conversion device includes a high-pass filter for extracting an AC component of voltage Vdc of a DC link section, a multiplier for multiplying output VdcAC of the high-pass filter by a first gain K1 and outputting the result, a multiplier for multiplying output of the multiplier by a second gain K2 and outputting the result as a d-axis voltage correction signal vdcmp*, and a multiplier for multiplying output of the multiplier by a third gain K3 and outputting the result as a q-axis voltage correction signal vqcmp*. The gate signal generation section generates gate signals on the basis of a signal vdobtained by adding the d-axis voltage correction signal vdcmp* to a d-axis voltage command value vd* and a signal vqobtained by adding the q-axis voltage correction signal vqcmp* to a q-axis voltage command value vq*.
