CONTROL DEVICE AND POWER CONVERSION DEVICE

According to an embodiment of the invention, a control device is provided and controls a power converter that can be connected to a terminal of a direct current power transmission system transmitting power according to a current command value that is set. The control device includes a first characteristic setter having a first characteristic preset. When the power converter is set at a power transmission end of the direct current power transmission system, the first characteristic outputs an output terminal voltage for the power converter. The output terminal voltage corresponds to a current of a current control based on a current command value set at a power receiving end of the direct current power transmission system. The output terminal voltage of the first characteristic monotonously decreasing with respect to the current of the current control.
