A power conversion device includes a power conversion circuit and a control device. The control device includes a virtual power generation device model unit and a control signal generation unit. The virtual power generation device model unit includes: a motor model unit; an AVR model unit; an angular velocity difference acquisition unit; and a power generator model unit. The control signal generation unit is configured to generate the pulse width modulation signal based on the current command value and an output current value from the power conversion circuit.

Power conversion device with virtual power generation model

A power conversion apparatus includes a plurality of power conversion units, a common bus bar, and a plurality of unit bus bars provided so as to correspond to the plurality of the power conversion units respectively and connecting each DC side of the plurality of the power conversion units to the common bus bar. Each of the power conversion units includes a casing having a first surface on which a first outer plate of a magnetic material is arranged, and the first outer plate is arranged in a vicinity of a corresponding unit bus bar and faces the corresponding unit bus bar with a gap so that an inductance value of the corresponding unit bus bar is increased to an inductance value capable of suppressing an inflow of a ripple current from another power conversion unit in the power conversion apparatus.
