Abstract
There are a power module and a distributed power supply apparatus having the same. The power module includes: a power factor correction stage switching input power to correct a power factor thereof; a DC/DC conversion stage switching the power of which the power factor has been corrected by the power factor correction stage to convert the power into preset DC power; a control unit controlling the power factor correction stage and the DC/DC conversion stage to perform a power conversion operation in a preset powered mode and stopping the power conversion operation of the DC/DC conversion stage in a preset idle mode; and a reference voltage supply unit supplying a preset reference voltage to the DC/DC conversion stage in the idle mode.
