Abstract

An integrated converter is provided. The integrated converter includes an AC/DC converter electrically connected to a three-phase power supply for converting an alternating current into a first direct current and achieving the object of the power factor correction; and a DC/DC converter electrically connected to the AC/DC converter for converting the first direct current into a second direct current, wherein while the AC power supply is electricity-drop, the controlling switch is turned on by the integrated converter and the integrated converter is switched from an AC/DC working mode to a DC/DC working mode, and while the AC power supply is restored to normal, the controlling switch is turned off by the integrated converter and the integrated converter is switched from said DC/DC working mode to the AC/DC working mode.
