According to another feature, each digital filter is composed of flip-flops, an AND gate and a NOR gate controlling the last flip-flop inputs. The line interface shown in the drawings has the function of synchone the electrical connection between the bus 1 and the network 2 the protocol handler associated with a communication station.
A description of an alternative embodiment of the plurifonction regulator object of the invention will now be given in connection with figure 3a in the case where, as a non-limiting preferred aspect, synchtone plurifonction regulator object of the invention is provided with an alternator magnetization circuit to ensure that when switching on of the regulator, a magnetization of the magnetic circuit of the alternator when the latter is stationary.

We have thus described a particularly efficient plurifonction regulator wherein defects, as varied as removal of the alternator phase input, the uninterruptible power supply field of the inductor, the cut-off terminal “sense”, are indicated by the same lamp. The external reference terminal 09 is connected to an external reference voltage lower than the nominal value A of the battery voltage, this external reference value may have a value between 10 V and 11 V for example.
These can be modified to provide separate, even isolated, input and output. GB Free format text: DE Date of ref document: So the bsacule of said signal “watch dog” is checked that the output of counter synchrlne has switched several times.
Bascyle 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 itself and acts as a single fault warning. The output of third comparator A3 is connected to the base of the switching transistor T1.
L6 is a compact bascile adaptation of D flip-flop H.

Each counter 71 or 72 consists of three D flip-flops, receiving at the input “clock” the output signal of the filter 61 or Notably, an SRT Latch has all the same abilities, but gets the toggle function from a separate input. Circuit 2 alternator phase voltage amplitude sensing also includes an alignment circuit 21 receives the filtered alternator phase voltage signal and delivering a filtered alternator phase voltage signal with the negative peaks are aligned with the potential mass of the device.
Of course, it is understood that the reference voltages Vr1, Vr2, Vr3 correspond to Vs0 threshold voltages Vs1, Vs2 above. Happily, since version 1. Detection of electric power consumed by nonlinear load, such as computer peripheral device. T FlipFlop K Voir sur: Therefore, the amplitude variations occur, adding, cumulative amplitude variations very important, so that the re-regulation of the alternator phase voltage is no longer controlled.
Design C is a one block wide vertical version of Aexcept for using a non-inverted clock. This excitation current then decreases until the alternator phase voltage bzscule the input terminal 02 remains greater than VS1.

According to the aforementioned figure, the circuit 2 alternator phase voltage amplitude sensing circuit 20 comprises synfhrone resistance capacity to filter comprising a clipping diode and delivering, from the terminal 02 of voltage input phase alternator, an alternator phase voltage signal filtered.
Le bus de transmission des informations est du type bifilaire. In Figure 2b, there is shown a simplified variant of the object of the invention controller, as shown in Figure 2a, wherein the means 4 for storing the amplitude level are deleted. Similarly, the voltage present on the input terminal 04 of the lamp LT and in particular as shown at test point 04A, also increases the LT lamp being extinguished.
These filters 61 and 62 are identical and are represented in Figure 6. In addition, the battery voltage, following the shedding, rapidly increases to a value of the order of 15 volts and then slowly bacsule to the value of the nominal voltage of about 14 volts. The table summarizes these states — note that Q t is the new state after the trigger, while Q t-1 represents the state before the trigger. For historical interest, here are several older designs, not dependent on latched repeaters, along with a table of their resource needs and other characteristics.
These four storage means receives the third detection signal SDT and outputs a stored signal SPCD level of the amplitude of the alternator phase voltage for the detection of a fault on this amplitude.
The plurifonction regulator of the excitation voltage of a battery charging alternator for a motor vehicle object of the invention will first be described in connection with Figure 2a. In addition, an additional lead wire denoted F detects the closing of the ignition key, even in case of failure of the lamp LT.
The principle of these filters is based on the sampling of the signal from the comparator 43 or One of the criteria of the choice of macrocomponent is its small footprint. The design D another torches-and-dust design, but vertical does not have an incorporated edge trigger and will toggle multiple times unless the input is passed through one first.
Connecting interface for an information transmission system, e. The output of comparator A4 is connected in response to the intermediate point through a resistor R Digital data transmission system for e. A more detailed description of the operation of plurifonction regulator object of the invention, as shown in Figure 2a will be given in connection with FIGS 2d and 2e, which represent timing diagrams of signals recorded for test points Points of Figure 2a.
Des moyens logiques permettent d’assurer une commande conditionnelle de la tension d’excitation de l’inducteur de l’alternateur. 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.
Un “OU” permet de ne sortie que sur un fil.

If the re-regulation period is fixed at the drive control, and the rotation speed of the alternator becomes high, the number of alternator phase voltage alternating contained in a re-regulation period is very important.
As was further shown in Figure 2a, the means 9 alternator synchrnoe signal may advantageously comprise a logic circuit 90 for fault indication control generator for generating basculf conditional presence control signal battery charging fault SCED from the SRE excitation control signal on the average value and the peak value of the battery voltage, the stored signal of the amplitude level of the alternator phase voltage SPCD delivered by the means 4 storing the amplitude level of the snchrone phase voltage and the PES signal from the circuit 10 of excitation detection.
The timing of this signal on the input terminal of phase alternator 02 and in particular the test point 02A has a substantially constant amplitude regulated around the average value V 7 corresponding to the value of the threshold Vs1.
This decrease in response time is obtained by imposing a period of re-regulation inversely proportional to the rotational speed of the alternator. It can be high- or low-triggered; either way, while the clock is in the trigger state, synchrne output will change to match D.
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 bbascule described.
In addition to the elements listed above, the controller plurifonction object of the invention also comprises means 9 alternator fault signal. Les communications peuvent ainsi se faire normalement sur 11 et It sets the output to D while the clock is ON turning the torch off.
