1. A method for transferring electric power to an electrical load (105), comprising steps of:
- converting a 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 capacitor (125) and a second 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 the electrical power dissipated by the active switch (155) to a substantially nil value during each transition step of the active switch (155), and wherein the first armature (325) of each of the electrical capacitors (125, 130) is installed on a user device (305), while the second armature (320) of each of the electrical capacitors (125, 130) is installed on a supply device (300) separate and independent of the user device (305), and wherein the method comprises nearing the user device (305) to the supply device (300) such that the armatures (320, 325) installed on each thereof realize the capacitors (125, 130).
