Disclosed is a power management apparatus and a multi-source energy harvesting system using the apparatus, which manage power supplied by individual harvesting sources without wasting the power, thus efficiently distributing the power to a battery. The power management apparatus includes a plurality of comparison units configured to compare voltages of storage devices respectively connected to output terminals of a plurality of harvesting power sources with a preset threshold voltage. A control unit is configured to control an operation of the power management apparatus. A plurality of switching units are installed between the storage devices and a battery and are configured to be turned on/off in response to switching control signals output from the control unit and to form power transmission paths between corresponding storage devices and the battery. The control unit generates and provides the switching control signals based on output signals of the comparison units.
