Abstract
There are provided a power module in which a bias voltage is varied and supplied to a control circuit controlling power conversion when an idle mode is switched to a normal mode, and a distributed power supply apparatus having the same. The power module includes: a power factor correction stage; a DC/DC conversion stage switching power to convert the power into pre-set DC power in a powering mode in which normal power is output; a standby stage converting the power into pre-set standby power in a cold standby mode in which the DC/DC conversion stage outputs power having a level lower than that of normal power; and a variable bias supply unit varying a voltage level of bias power for controlling DC/DC power conversion and supplying the same to the DC/DC conversion stage in the cold standby mode and the powering mode.
