  • Publication number: 20220077763
    Abstract: The invention relates to a switch system (1) comprising a power line (2) for supplying a charge from a voltage source (+Vbat), said power line having a main switch (Q1) comprising a first main terminal (D) and a second main terminal (S), between which a main current (Ip) is intended to pass, and a control terminal (G) for selectively placing the main switch (Q1) in a closed, open or semi-closed state, the main switch (Q1) in its semi-closed state being equivalent to a variable resistor controlled by the control terminal and connected between the first and the second main terminal, characterized in that the switch system (1) further comprises a current-limiting device (3) designed to, when the main current (Ip) exceeds a maximum current threshold, decrease a control current (Ig) entering the control terminal (G), so as to cause the main switch (Q1) to transition from the closed state to the semi-closed state, so as to limit the main current.

  • Patent number: 9647600
    Abstract: The device according to the invention controls a polyphase inverter (10, 14, 17) intended for powering from a DC current source (CC) a polyphase rotating electric machine (1). The device is of the type of those generating commutation functions driving commutation elements (9, 13) of the inverter in such a way as to obtain a reduction of the losses in the commutation elements and a decrease of an effective current in a decoupling capacitor (16) of the source (CC). According to the invention, this reduction and this decrease are obtained by means of a set of control strategies (21, 24) determining the commutation functions by using additional degrees of freedom of the polyphase machine (1) with respect to a three-phase reference machine. The polyphase machine comprises first and second phase windings forming a first three-phase system (2, 3, 4) and a second three-phase system (5, 6, 7) with distinct neutral points (11, 15) offset angularly by a predetermined angle of offset (?).
