Les bascules RS appliquent directement ce principe. The “any” blocks can be air, and that torch can just as well be on the ground. The torch-based edge trigger could also be replaced with one of the designs from the Pulse circuit page.
Method for managing the excitation of an automobile alternator by means of a regulator. A more detailed description of the circuit 2 alternator phase voltage amplitude sensing will be given in connection with Figure 2a. However, the delay between the input pulse and the output transition is also longer. In the above relation, value Vs2 represents the comparison of threshold voltage of the amplitude of the alternator phase voltage detection circuit, A represents the nominal battery voltage, UB represents the actual battery voltage and the Up alternator phase voltage.
Indeed, an increase in the rotational speed of the generator increases the frequency of the synchronous timing signal validated SCSV flip-flops 30 to GB Ref legal event code: Any RS latch with dual outputs is functionally symmetrical: Conditional command logic means 6 further includes a second NOR gate 61 respectively receiving on its inputs the signal SRE excitation regulation of the peak value and the average value of the battery voltage and the signal SCAVE enable control excitation output from the first NOR gate 60 described above.
A more detailed description of the fault indication control logic circuit 90 will be given in conjunction with Figure 2a.
Figures 5a, 5b, there is shown the evolution of various test points in the signals of Figure 2a or 3a in the case of the removal of a significant operation load on load shedding for example. If they don’t have to be right next to each other, dust can be used instead of the output repeater. Country of ref document: The detection circuit 1 also comprises a third comparator A3.
In addition, the regulator plurifonction object of the invention is particularly advantageous in that it can take into account if necessary auxiliary circuits, such as magnetization circuits of the inductor of the alternator, in the absence of rotation thereof. It is further noted that as in the case of single-function controllers that conventional multifunction controllers are not subject to a total integration on a single substrate, a screen-printed conductive pattern to be used for interconnecting the various semiconductor components -conducteurs constituting the controller.
The object of the invention plurifonction controller also comprises means 5 of timing, means 3 for storing and controlling the excitation of the inductor, as well as means 4 for storing the amplitude level of the alternator phase voltage.
This pre-excitation control circuit essentially comprises a threshold comparator 82 receiving on its negative terminal of a fixed voltage generated by the Zener diode DZ polarization polarized via the connection terminal 04 of the lamp LT on closing the key contact K of the motor vehicle. T flip-flops are also known as “toggles. The cathode of the diode is connected to the terminal 04 of the lamp LT.
The sampling frequency is set so that there are at least three samples per bit taking into account the clock drifts. The aforesaid second detection signal is zero if the phase voltage of the generator present on the input terminal 02 is less than VS1, and corresponds to synchronous pulses of the alternator phase signal otherwise. Each counter 71 or 72 is of the synchronous type and operates on the falling edge of the clock.

The voltage delivered by the comparator 25, following the triggering cited in NOR gatesignal failure due to lack of battery charge. Load limiting method and device for a mechanical appliance or the like, using at least one electrical-type motor member.
This SCRV re-regulation control signal to the alternator phase voltage is limited in time by a change in level of the last status enable signal SAEP full field and to prevent further alternator phase voltage re-regulation in event of a fault on circuit 2 for detecting the amplitude of the alternator phase voltage or disconnection of the phase input terminal 02, as will be described later in the description. A regulator according to claim 22, characterized in that, for a monolithic realization on the same substrate of semiconductor material, said peak value memory circuit comprises a transistor TA1a capacitor C3 constituting storing the value of peak envelope circuit connected on the one hand, to the emitter of the transistor TA1 through a resistor R and, secondly, to the voltage reference VM of the regulator, a transistor TR being provided to compensate, at the discharge of the capacitor C3 the emitter-base junction voltage introduced to the load by the transistor TA1.
The timing of all the flip-flops 30, 31, 32, 33 by means of the synchronous control signal SCS to the rotation of the generator is particularly advantageous for the following reasons.
In Figure 2a, it was noted respectively R to R all bias resistors of the detection circuit 1. Now a gated D latch can be made with two repeaters, and a D flipflop with four repeaters and a torch:. The minimum number of switchings counted by 75 a message on the bus is at least equal to the minimum number of transitions of a message frame.
Bascule 91 Switches The embodiments described do not prejudge technology embodiments by discrete elements, which do not depart from the scope of the object of the present invention. Regulator according to one of claims 1 to 5, characterized in that it further comprises means 4 for storing the amplitude level of the alternator phase voltage, said means 4 for storing, clocked by the means 5 timing, receiving said third sensing signal TSD and delivering a stored signal SPCD the level of the amplitude of the alternator phase voltage for the detection of a fault on this amplitude.
According to another feature, the storage flip-flops output signals are sent to a defect recognition circuit comprising “NOR” circuits.

The state of torque output of the latches 91 or 92 is decoded by the 4 “NOR” circuit As has been shown, furthermore, in Figure 2a, the controller plurifonction object of the invention also comprises means 3 for storing and controlling the excitation of the inductor of the alternator. Sjnchrone, on the second face, was then shown the voltage at test point 6A, that is to say the ECS signal from the logic means conventional controller 6 when the alternator basculle voltage signal rises above the first threshold value Vs0, that is to say when the amplitude of the alternator phase signal, peak to peak amplitude becomes greater than 0.
A regulator according to claim 18, characterized in that the second reference voltage Vr2 is greater than the peak value of the parasitic overvoltages applied to the second input of the second comparator 23 when the alternator is not rotating or that the syncrone alternator phase input 02 is disconnected from the alternator to discriminate these parasites surge alternator phase signal.
In addition, a first voltage comparator 22 is provided for receiving at a first positive input a first reference voltage VR1 and a second negative input the basculr alternator phase voltage signal aligned.
Both are extremely compact, thanks to the use of latched repeaters. Certains registres sont toutefois plus complexes. As was also shown in Figure 2a, the plurifonction regulator object of the invention can comprise means 4 for storing the amplitude level of the alternator phase voltage.
