    Abstract: PROBLEM TO BE SOLVED: To provide a switched power converter, which has a small number of switching devices and a high overall efficiency. SOLUTION: This universal switched power converter has a transformer, comprising a 1st winging 11-3 divided into two parts and having an intermediate tap 11-3-1, and a 2nd winding 11-9, connected in cascade with a rectifier means 12 and a filter means 13. A 1st current flows through the part of the 1st winding 11-3 located between the end of the 1st winding 11-3, connected to a 1st input terminal 11-1 and the intermediate tap 11-3-1 and through a 2nd switching device 11-6, connected to the intermediate tap 11-3-1 and to a 2nd input terminal 11-2, when the input voltage applied across the input terminals 11-1 and 11-2 is close to a 1st prescribed voltage value and the 2nd switching device 11-6 is in a conducting state.
