<P>PROBLEM TO BE SOLVED: To provide a power converter contributive to the enhancement of performance, the simplification of adjustment and the like, in a motor drive employing an inverter power converter 3. <P>SOLUTION: The power converter comprises a power converter 1 having a switching element, and an output voltage control means 20 generating a gate command to the switching element so that an output voltage from the power converter coincides with an output voltage command. The power converter is further provided with a voltage detector 4 for detecting the output voltage from the power converter 1, an error voltage estimating means 18 for operating an error voltage based on an output voltage detection value and an output voltage command, and a voltage correction means 7 for correcting the output voltage command value based on the error voltage estimation value. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
