Disclosed are a converter control device and a control method. The device comprises: a first switching element connected to each end of at least one first battery; a second switching element connected to the other end of the first battery and connected in series with the first switching element; a third switching element connected to one end of a second battery; a fourth switching element connected to the other end of the second battery and connected in series with the third switching element; an inductor connected to a first node between the first switching element and the second switching element and a second node between the third switching element and the fourth switching element; and a duty controller for receiving each first voltage which is a voltage value of each end of the first battery and a second voltage which is a voltage value of one end of the second battery, and for outputting duty of the respective first switching element based on the first voltage and the second voltage. The present invention can improve efficiency by simplifying a package by additionally connecting the switching element to an input terminal of a converter.
