  • Converter for transferring electric power to an electrical load
    Patent number: 11967902
    Abstract: A converter (145) is described comprising: a first input terminal (150) and a second input terminal (155), a first output terminal (165) and a second output terminal (170) connectable to opposite ends of the electrical load (110), a first electric branch (201) adapted to connect the first input terminal (150) with a first intermediate electrical node (202), a second electric branch (203) adapted to connect the first intermediate electrical node (202) with the second input terminal (155), a third electric branch (205) adapted to connect the first output terminal (165) with a second intermediate electrical node (206), a fourth electric branch (207) adapted to connect the second intermediate electrical node (206) with the second output terminal (170), a first active switch (180) placed on the second electric branch (203) and having a first conduction terminal (185) and a resonant circuit (200) sized to reduce the electric voltage and/or electric current applied to said first active switch at least in the moments
    Type: Grant
    Filed: May 25, 2020
    Date of Patent: April 23, 2024
