Abstract
A control device for a power conversion apparatus that can prevent a rush current from flowing into a power converter. In a power conversion apparatus with a power converter connected with a DC power supply, a filter, and a switch connected with an AC power supply are connected in series in that order, a control device for the power conversion apparatus includes: a calculation unit configured to calculate, from a value of an AC current flowing between the power converter and the filter and impedance of the filter, an estimated value for AC power to be outputted by the power converter; and a control unit configured to control an action of the power converter in a state that the switch is open such that a difference between a target value for AC power and the estimated value falls within an allowable range set in advance.
