Abstract:
The purpose of the present invention is to suppress current distortion due to load-side AC voltage, magnetic saturation (nonlinear) characteristics of a motor, etc., in a power conversion device and a motor drive device. A power conversion device for performing power conversion between an AC power supply and a DC loader between DC power supplies is provided with: an inverter circuit; a current detection means for detecting the AC current of the AC power supply; a voltage controller for generating a command voltage for the inverter circuit on the basis of an AC current signal detected by the current detection means; and a correction unit having a gain with respect to a specific frequency and correcting the command voltage on the basis of the AC current signal. The correction unit is configured to correct the command voltage that has been output from the voltage controller.

Claim (Index 5):
A motor drive device having an inverter circuit to convert a direct voltage into an alternating voltage and current detection means for detecting an alternating current as output from the inverter circuit, the motor drive device comprising:\n a voltage controller that generates a command voltage for the inverter circuit based on an alternating-current signal detected by the current detection means; and a corrector that includes a gain corresponding to a specific frequency and corrects the command voltage based on the alternating-current signal, wherein the corrector is configured to correct the command voltage after being output from the voltage controller, and uses a transfer function shown in the following equation. G \ue8a0 ( s ) = K 1 \u00b7 s 2 + K 2 \u00b7 s s 2 + K 3 \u00b7 s + \u03c9 0 2 [ Math . \ue89e 1 ] where s denotes a Laplace operator; \u03c9 0  denotes a center frequency; and K 1 , K 2 , and K 3  denote control gains.
