摘要：
A control device (50) for a power converter is to be applied to a system comprising a chargeable/dischargeable power storage device unit (30), coils (11U-11W, 72, 83, 84), and a power converter (20, 70, 80) that electrically connects the coils and the power storage device unit. The control device is provided with: a determination unit for determining whether or not the temperature of the power storage device unit is required to be increased; and a temperature increase control unit for, upon determination by the determination unit that the temperature of the power storage device unit is required to be increased, performing switching control for the power converter so as to repeat, in a prescribed period, one cycle composed of a coil charging mode in which the electric current amount in the coils is gradually increased and a coil discharging mode which is a mode after the coil charging mode and in which the electric current amount in the coils is gradually reduced, and so as to set the electric current amount in the coils to more than zero.
