Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/017304
Kind Code:
A1
Abstract:
A power conversion device is equipped with: a high-pass filter (12) for extracting an AC component of the voltage (Vdc) of a DC link unit (5); a multiplier (13) for multiplying the output (VdcAC) from the high-pass filter (12) by a first gain (K1) and outputting the result; another multiplier (15) for multiplying the output of the multiplier (13) by a second gain (K2) and outputting the result as a d-axis voltage correction signal (vdcmp*); and still another multiplier (16) for multiplying the output of the multiplier (13) by a third gain (K3) and outputting the result as a q-axis voltage correction signal (vqcmp*). A gate signal generation unit (17) generates a gate signal on the basis of a signal (vd1) obtained by adding the d-axis voltage correction signal (vdcmp*) to a d-axis voltage command value (vd*) and a signal (vq1) obtained by adding the q-axis voltage correction signal (vqcmp*) to a q-axis voltage command value (vq*).
