Power converter apparatus

摘要

A power converter apparatus includes a control mechanism for sampling input signals at a sampling frequency and generating an alternating current control voltage in response and for generating a two-axis voltage command. A phase correcting mechanism operating at a second frequency higher than the sampling frequency is provided for correcting the phase of the control voltage at the second frequency. A coordinate converting mechanism converts the voltage command into a multi-phase voltage command in response to the phase of the voltage after the phase correction by the phase correcting mechanism.
