Patent ID: 11355962

Abstract:
The invention describes an apparatus (100) for transferring electrical power to an electrical load (110), comprising: a primary circuit (115), an electrical source (105) adapted for supplying said primary circuit with a direct input voltage, a secondary circuit (120) adapted for feeding the electrical load (110), and a coupling device (125) adapted for transferring electrical power from the primary circuit (115) to the secondary circuit (120), wherein the primary circuit (115) comprises: a converter (300) adapted for receiving the input voltage, for modifying said input voltage and for outputting said modified voltage, and a wave generator (190) comprising at least one switching circuit provided with at least one active switch (250), which is adapted for receiving in input the modified voltage in output from the converter (300), for converting said modified voltage into voltage waves and for applying said voltage waves to said coupling device (125), and wherein said converter comprises at least one active switch (315) adapted for selectively allowing or preventing the passage of electrical current from the electrical source (105) to the wave generator (190).
