Switched power supply converter for broad range of input voltages

Universal switched power converter having a transformer that comprises a first winding ( - ) divided into two parts and having an intermediate tap ( - - ), and a second winding ( - ) connected in cascade with rectifier means ( ) and filter means ( ), so that a first current flows through the part of said first winding ( - ) comprised between the end of the primary winding ( - ) connected to a first input terminal ( - ) and the intermediate tap ( - - ) and through a second switching element ( - ) connected to the intermediate tap ( - - ) and to a second input terminal ( - ), when the input voltage applied across the input terminals ( - - ) is close to a first predetermined voltage value and the second switching element ( - ) is in a conducting state.
