1. A method for transferring electric power to an electrical load (105), comprising steps of:
- converting an direct electric current into an electric tension wave,applying the electric tension wave in inlet to at least a couple of electric capacitors (125, 130) including a first electric capacitor (125) and a second electric capacitor (130),supplying the electrical load (105) with the electric tension in outlet from the capacitors (125, 130),wherein the conversion step comprises;
alternatingly switching a single active switch (155) on and off, andlowering electrical power dissipated by the active switch (155) to a substantially nil value during each transition step of the active switch (155).

10. An apparatus (100) for transferring electric power to an electrical load (105), comprising:
-
at least a pair of electric capacitors (125, 130) including a first electric capacitor (125) and a second electric capacitor (130), converter means (135) for converting a direct electric tension into an electric tension wave, means for applying the electric tension wave in inlet to the capacitors (125, 130), means for supplying the electrical load (105) with the electric tension in outlet from the pair of electric capacitors, wherein the converter means (135) comprise a switching circuit comprising; a single active switch (155), means (160) for generating an electrical pilot signal suitable for switching the active switch (155) on and off, and a reactive circuit (145) set up such as to lower electrical power dissipated by the active switch (155) to a substantially nil value, during each transition step of the active switch (155). - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
