PURPOSE: A photovoltaic module is provided to facilitate the use of a power source by including a control unit controlling the operation of a converter within a junction box. CONSTITUTION: A DC/DC converter(530) level-shifts a DC power supply and outputs the DC power supply. The DC power supply is supplied to a photovoltaic module(50). A DC load is connected to an output node of the DC/DC converter. A control unit(550) controls the operation of the DC/DC converter based on an output voltage. A junction box(115) comprises the control unit, an output current detection unit, and an output voltage detection unit.
