Abstract
A power management device may include a first power conversion device configured to output a first driving voltage, a second power conversion device configured to output a second driving voltage, and a third power conversion device configured to output a third driving voltage. The first driving voltage may be changed in a range of positive voltage and the second driving voltage may be changed in a range of negative voltage. The third driving voltage may be smaller than the first driving voltage and greater than the second driving voltage, and may be changed as a driving voltage at a point where a sum of a first power consumption due to the changed first driving voltage and a second power consumption due to the changed second driving voltage is the smallest.
