Abstract
A control device for a power conversion apparatus and a resistor for a power conversion apparatus that can suppress a cross current between a plurality of power converters. A control device for a power conversion apparatus includes, in a state that AC sides of a plurality of power converters are connected in parallel without DC sides of the plurality of power converters being connected in parallel: a voltage recognition unit configured to recognize a voltage to ground on a DC side of a power converter, being an object to be controlled; and a controller configured to control, based on the voltage to ground on the DC side recognized by the voltage recognition unit, a DC voltage of the power converter, being the object to be controlled, such that the voltage to ground on the DC side of the power converter, being the object to be controlled, is further reduced.
