  • Circuit for controlling the current in an electrical control member or the voltage across the terminals of said electrical control member
    Patent number: 8576581
    Abstract: The present invention relates to a circuit (300) for controlling the current in an electrical control member (110) comprising a bridge provided with four terminals (105, 106, 107, 108) and comprising four control switches (AH, AL, BH, BL), a power source (109), PWM control means for at least two of the four switches. The control circuit exhibits a first state in which said first (AH) and fourth (BL) switches are closed and said second (BH) and third (AL) switches are open, a second state in which said second (BH) and third (AL) switches are closed and said first (AH) and fourth (BL) switches are open and at least one of the following two states: a third state in which said third (AL) and fourth (BL) switches are closed and said first (AH) and second (BH) switches are open and/or a fourth state in which said first (AH) and second (BH) switches are closed and said third (AL) and fourth (BL) switches are open.
