This paper presents a novel common‐source active clamped complex type converter. This converter is the intermediate isolated bus converter for the distributed power supply system in telecommunications equipment. Using active clamped circuits, the switching loss and switching noise can be reduced by means of the soft switching techniques. By adding an auxiliary winding to the transformer, the proposed converter is a common‐source type having direct connection of sources of the two MOSFET switches. As a result, the pulse transformer becomes unnecessary, and the drive circuit is simplified. In the experiment, at 48 V ratings input voltage, 36 to 72 V worldwide input voltage, and 12 V output voltage, the ZVS operation is performed on the main switch and auxiliary switch, and highest efficiency 92.7% is obtained. © 2009 Wiley Periodicals, Inc.
