Abstract:
A power converter control apparatus for sending an alternating-current voltage command, subject to a voltage command and a frequency command, to a power converter for converting a direct-current voltage into a variable alternating-current voltage of a variable frequency, said power converter control apparatus comprising:a detector for detecting an amount of electricity generated at the direct-current side of the power converter, a high-pass filter for removing direct-current components from the detected amount of electricity, a voltage corrector for correcting said voltage command in accordance with an output signal from said high-pass filter, and a frequency corrector for correcting said frequency command in accordance with said output signal from said high-pass filter, wherein an alternating-current voltage command is issued in accordance with output signals from said frequency corrector and said voltage corrector.
