Title
(EN) SYSTEM FOR TRANSFERRING ELECTRICAL POWER TO AN ELECTRICAL LOAD
(FR) SYSTÈME DE TRANSFERT D'ÉNERGIE ÉLECTRIQUE À UNE CHARGE ÉLECTRIQUE
Abstract
(EN)
The invention describes a system (100) for transferring electrical power to an electrical load (110), comprising: a direct electrical voltage source (105), and at least one wave generator (145) adapted for converting the direct electric voltage into voltage waves to be transmitted to the electrical load (110); wherein said wave generator (145) comprises at least: an active switch (180) provided with two connection terminals (185, 190) and adapted for being controlled by an electric control signal between a saturation condition, in which it allows the passage of electrical current between said connection terminals (185, 190), and a prevention condition, in which it prevents said passage of electrical current, and a resonant circuit (200) sized to reduce the electrical power applied to said active switch (180) in the moments in which said active switch switches from the saturation condition to the prevention condition and vice-versa; and wherein said resonant circuit (200) comprises at least: a central electrical node (215) to which a first connection terminal (185) of the active switch (180) is connected, a first electrical branch (205) extending between said central electrical node (215) and a first terminal (210), a second electrical branch (220) ex-tending between said central electrical node (215) and the first terminal (210) or between said central electrical node (215) and a further terminal (235) connected to a reference voltage, a resonance inductance (225) arranged on the first electrical branch (205), and a resonance capacity (230) arranged on the second electrical branch (220).
