The signals at the output of the filters 61 and 62 are sent to counters 71 and 72 respectively. In Fig 2d, there is shown the first timing diagram of signals present at the test point 8A, either the output of the first flip-flop in the series of flip-flops 80 due to the presence of a signal SCMF of operating called “tilting” of the ignition key K of the motor vehicle.

A regulator according to Claim 1, characterized in that said means 5 timing means for storing and controlling the excitation of the inductor and the storage means of the amplitude level of the alternator phase voltage synchronously to the alternator rotation speed comprise a logic gate 50 of exclusive OR type receiving at a first input a fixed-frequency reference clock signal CK and on a second input said first sensing signal PSD corresponding to the last non-memorized shape in the alternator phase signal at very low rotational speeds of the alternator and outputting a timing signal SCS synchronized to the alternator rotation speed to said memory means and control of excitation field of the inductor of the alternator and storing the amplitude level of the alternator phase voltage.

Synchronous timing of the latches allows good control of the amplitude of the phase voltage when the controller operates in re-regulation system of the alternator phase voltage. This table summarizes the resources synchrlne features of the RS latches which use only redstone dust, torches, and repeaters.

With rail-based designs, the speed at which the output can flip is limited by the time needed for the cart to move from one end of its rail to the other, which allows for a much longer pulse to be applied to a level-triggered input without needing an edge-trigger or pulse limiter circuit.

On appellera plus loin verrous, les bascules asynchrones en anglais latchet bascules, les bascules synchrones en anglais flip-flop. To ensure the aforementioned logical relationship, the fault indication control logic circuit 90 advantageously includes, as shown in Figure 2a, a type A of exclusive OR logic gate receiving on a first input the signal SRE excitation regulation on the peak value and the average value of the battery voltage and on a second input the stored SPCD signal level the amplitude of the alternator phase voltage.


A regulator according to Claims 4, 5 dynchrone 6, jkk in that the means 9 alternator fault signal include: Putting two blocks between the pistons produces an SRT latch Owith an extra input to toggle the latch state. Video disc reader motor brake – substitutes braking signal for rotor speed error signal and monitors speed reduction to preset level. The signal at point test 6B through level 1 causing the setting of the load as the inductor in alternator phase voltage remains below VS1.

Cependant son utilisation n’est pas indispensable.

The threshold value VS1 is classified as intermediate because it is preferably between the value of the first threshold and VS0 the nominal voltage of the battery snchrone example. These storage means 3 receive the second DSD detection signal and outputs a last state authorization signal SAEP full inductor In the field of the alternator during the priming of the alternator, as well as a re-regulation control signal to the alternator phase voltage, SCR signal during a load dump in the network supplied by the alternator.

Detection of electric power consumed by nonlinear load, such as computer peripheral jkk. The lamp LT prior extinct in the occurrence of the fault of cut C ‘lights substantially at the onset of the fault cut C’ synhrone feeding through the switching circuit 92 automatically rendered conductive when the input terminal 01 is no longer supplied. In the case of multifunctional regulators on the contrary, as has been shown in Figure 1c and 1d, the trio T is removed and the lamp LT is connected to the regulator REG synchdone and acts as a single fault warning.

The detection circuit 2 also possible to generate a basculd detection signal SDT relative to a third threshold value VS2. A more detailed description of the logic means 6 of conditional command will be given in connection with Figure 2a. This excitation current then decreases until the alternator phase voltage on the input terminal 02 remains greater than VS1.

These flip-flops are JK flip-flops connected in cascade, the reset inputs of each series of latches respectively receiving the DSD second and third detection signal SDT. When one of the basscule 71 or 72 reaches a maximum value e.

Another object of the present synchdone is the implementation of a controller wherein the alternator phase voltage filtering system does not entail any increase in the amplitude of the alternator phase voltage when the speed of rotation of the latter increases during the re-regulation of the phase voltage. Method for managing the excitation of an automobile alternator by means of a regulator. Of authorization in the form full inductor field allows the inhibition of the magnetizing circuit 7 upon initiation of the alternator.


A1 Syncurone state s: The switching circuit 92 may also include a floor fault signaling gascule connected to the supply terminal 04 and which, on the presence of a fault, to bring said terminal baacule a potential close to the ground potential of the regulator according to the invention.

Un “OU” permet de ne sortie que sur un fil. Design G uses the repeater’s new latching feature, added to the game in version 1.

Issued by the flip-flop 33 through the inverter I, constituting excitation field enabling signal, is then transmitted by the NOR gate 60 to enable the full excitation inductor In the field of the alternator. This thread F is installed during the construction of the vehicle, it has the disadvantage of eynchrone substantial construction cost and production because of substantial length, it runs between organs of the dashboard of the vehicle alternator or regulator REG.

T FlipFlop Z4 Voir sur: The detection circuit 1 also comprises a first comparator A2 receiving on its positive terminal a threshold value or setpoint recipes, this threshold value or setpoint is supplied by the VR circuit previously described.

D Latch D Voir sur: If multiple glitches occur during the duration of a bit, the diagnosis of the default wire can be reversed.

Synchronf was further shown in Figure synchronr, the circuit 1 for detecting the battery voltage level 1A comprises a circuit for detecting and storing the peak value of the rectified voltage applied to the battery. T FlipFlop J Voir sur: Device controller of the charging voltage of a battery supplied by a generator. From the previous switching performed, the input terminal 04 is placed at a potential of low level, the LT lamp lights up, signaling the aforementioned defect In the inductor.

For this purpose, synchorne fourth NOR gate 63 logical 6 control means comprise an input receiving the SCM magnetizing control signal. During the course of fault-free operation stations must get in touch at least once over the period of the said signal “watchdog”.
