Power conversion device and control method for power conversion device

Abstract

A power conversion device and a control method for a power conversion device are provided that are capable of suppressing tracking control errors caused by the transfer characteristics of an output target. [Solution] This power conversion device 100 includes a power conversion unit 10 that converts input power and outputs it, and a control unit 11 that controls the power conversion by the power conversion unit 10. The control unit 11 includes a command value generation unit 20, a phase correction unit 40, and a tracking signal output unit 50. The phase correction unit 40 generates a command value I based on a phase correction amount δ calculated based on at least one of an output current Ia and a transfer function generated based on a model of an AC grid 250. * Correct the phase of
