摘要： The invention relates to a voltage regulator (43) for a motor vehicle alternator (44). The device comprises a control module (I) for controlling an excitation current (lexc) in an excitation winding (3) of the alternator (44) according to a difference (5) between a setpoint voltage (DO) and a control voltage (Dbat) of an on-board network (9). The on-board network (9) of the vehicle is powered by a battery (10) to which the alternator (44) is connected. According to the invention, the voltage regulator (43) further comprises a safety module (30) that monitors the control voltage (Ubat) and which is separate from the control module (I). In a particular embodiment, the control module (I) and the safety module (30) are connected electrically by external bonding interconnections.

摘要： The invention relates to a starter for a motor vehicle heat engine. The starter includes a rotary electric machine provided with a stator (3). The stator (3) includes a magnetic pole assembly wherein a permanent magnet (5) forms at least two poles of the magnetic pole assembly. The permanent magnet may have a cylindrical shape and be molded from a combination of magnetic particles embedded within a non-magnetic binder. Using this structure, the number of magnets used to create the stator may be limited in number, thereby limiting the necessary assembly steps to create the stator.

摘要： The method of control according to the invention slaves a DC voltage generated by the alternator to a predetermined setpoint value by controlling an excitation current flowing in an excitation circuit comprising an excitation winding of a rotor of the alternator. The excitation current is controlled by means of a semiconductor switch, in turn controlled by a control signal having a predetermined period. The method comprises a detection of a failure of the excitation circuit. At least one short-circuit of the excitation winding is detected. According to another characteristic of the method, the control signal is generated on the basis of a combination of a setpoint signal formed by pulses of the predetermined period exhibiting a duty ratio representative of the setpoint value and of a detection signal indicative of the short-circuit.

摘要： An electronic system includes a casing including a first bearing surface, a first busbar attached to the casing and including a first connection end having a first connection surface, and an electronic unit having a second bearing surface and including a second busbar having a second connection end having a second connection surface. The second bearing surface is intended to slide on the first bearing surface when the electronic unit is inserted into the casing. One from among the first bearing surface and the second bearing surface includes a ramp that is inclined relative to the insertion direction for deforming the second busbar so as to bring the second connection surface closer to the first connection surface when the electronic unit is inserted into the casing. An electrical assembly may include such an electronic system and a rotary electric machine.

摘要： A method for discharging an electrical energy storage unit of an electrical circuit includes a first switching system defining a DC/AC voltage converter and interposed between a first electrical sub-circuit, which includes the electrical energy storage unit and the electrical winding of the stator of a rotary electric machine. A second switching system defines a DC/DC voltage converter interposed between the first electrical sub-circuit and a second electrical sub-circuit. At least one electrical consumer forms part of the first electrical sub-circuit. The method includes detecting that the voltage across the terminals of the electrical energy storage unit exceeds a predefined threshold, and controlling at least one of the first switching system, the second switching system and the electrical consumer so as to reduce the voltage across the terminals of the electrical energy storage unit by circulating an additional current in the stator electrical winding, second switching system, or electrical consumer.
