Abstract
A power conversion device includes a power converter to convert power generated by a power generator into power to be supplied to a load, a target torque calculator to calculate a target torque of the power generator in accordance with an operation state of the load, and a power conversion controller to control the power converter based on a torque current command value and an exciting current command value for causing an output torque of the power generator to approach the target torque. Absolute values of the torque current command value and the exciting current command value calculated by the power conversion controller during the power generation by the power generator have a positive correlation.
