Abstract
Official abstract text for this publication.
A power conversion device formed of a converter for rectifying a single-phase AC voltage to a DC voltage and an inverter for driving an AC motor by converting the DC voltage to an AC voltage includes: a first compensation unit that uses a frequency component twice the frequency of the single-phase AC voltage with respect to the DC voltage outputted from the converter or a current outputted from the inverter as a compensation value for at least one of a torque command value, a current command value, a voltage command value, a frequency command value, and a phase angle command value; and a second compensation unit that uses the DC voltage outputted from the converter or a current outputted from the inverter after being subjected to low frequency cut-off processing and gain processing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A power conversion device, comprising: a converter for converting a single-phase AC voltage to a DC voltage through rectification; an inverter for feeding a motor by converting the DC voltage as an output of the converter to an AC voltage; a current command value generation unit for outputting a current command value for the motor according to a torque command value; a frequency command value generation unit for outputting a frequency command val…
