Provided are a device and a method for controlling a converter of a hybrid vehicle. According to an embodiment of the present invention, the device for controlling a converter of a hybrid vehicle comprises a monitoring unit, a comparing unit, a determining unit, and a control value adjusting unit. The monitoring unit monitors a state of charge (SoC) of a low voltage battery, an SoC of a high voltage battery, and a load value (LD) of an electric field load. The comparing unit compares the SoC of the low voltage battery with a first charging threshold value (Th1), compares the SoC of the high voltage battery with a second charging threshold value (Th3) and compares the LD of the electric field load with a load threshold value (Th2). The determining unit determines whether or not an output control value of the converter is adjusted according to a comparing result. The control value adjusting unit decreases the output control value of the converter more than normal control to increase a power supply amount to the electric field load of the low voltage battery; and increases the output control value of the converter more than the normal control to increase the power supply amount through the converter. The present invention can improve energy efficiency.
