Definitions

  • the present invention relates to a load control device inductive, in particular an electromagnet coil, with which a diode is associated recovery, this device comprising an electronic chopper switch arranged in series with the coil and controlled by a width modulator of pulses as a function of a signal delivered by a device for measuring the current of the coil.
  • Coil control devices of this type are well known.
  • the switch controlled by the pulse width modulator provides power the coil first with a high current called in order to close the circuit magnetic of the electromagnet, then with a reduced current called just holding necessary to keep the magnetic circuit closed.
  • He is also known to supply the pulse width modulator by means of a voltage circuit continuous from a continuous source or the alternative network.
  • the object of the invention is to enable the transistor to be controlled quick opening over wide supply voltage ranges and under voltage floating with respect to the voltage across the coil.
  • the power supply circuit of the width modulator pulse converter is a transformer with two secondary windings one of which is connected to the pulse width modulator and the other of which is connected to the gate of the opening transistor via a requested opening switch by the opening signal.
  • the opening switch is preferably an optotransistor whose opening causes the discharge of the gate capacitance of the opening transistor fast.
  • a circuit comprising a comparator of the DC supply voltage with at least one threshold, the output of the comparator being connected to a call / hold delay element and to a opening delay device via a logic element provided with an input for a low level on-off signal.
  • Figure 1 schematically shows a control device according to the invention for a contactor coil.
  • Figure 2 shows an example of the control of the opening transistor in the device of figure 1.
  • the device shown is intended to control a coil B of electromagnetic contactor or, optionally, the coils of two contactors interdependent associated in reversing assembly. It includes a chopping transistor T1 arranged in series with the coil, between the latter and a low potential point, by example 0 volts, and a fast opening transistor T2 also arranged in series with the coil, between it and a high potential line V +.
  • a recovery diode D is arranged in parallel with the series arrangement of the coil B and the transistor T2.
  • the transistors T1 and T2 are preferably insulated gate transistors; it is here MOS transistors, but they can also be bipolar gate transistors isolated so-called IGBT.
  • the coil B is connected directly to the line V + and the transistor T2 is arranged in series with the coil between it and its point of connection to diode D.
  • transistor T2 and diode D are connected in series and the coil B is arranged in parallel with the assembly T2, D.
  • the chopping transistor T1 is connected to the output of a modulator circuit of pulses 11 included in a controller circuit 10.
  • a sensor 12 of the current circulating in the coil B is connected to the circuit 11 via a peak intensity detector 13.
  • the elements composing circuit 11 or associated with circuit 11 are usual and do not will not be described further.
  • Transistors T1, T2 are IGBT components or N channel MOS.
  • the device has on the one hand terminals 14 supply and command to supply the various electronic circuits and determine the contactor on and off by means of a switch not indicated and on the other hand a control terminal 15 making it possible to determine the running and contactor shutdown by a low-level signal S, for example from a bus industrial or an appropriate control unit such as a programmable controller.
  • the supply and control terminals 14 are connected via a filter 16 to a rectifier 17 whose output at potential V + considered below as potential continuous, is connected to transistor T2, to controller circuit 10 and to a converter with transformer 20.
  • the converter 20 comprises two windings secondary 21,22 (see figure 2).
  • the windings 21,22 are connected respectively by conductors 23,24 to the controller circuit 10 to supply the latter and to a opening switch with isolated control 25; switch 25, for example a optotransistor, is controlled by the controller 10 via a conductor 26 to make passing or blocking transistor T2 in order to power the coil or not.
  • the driver 26 is connected to an opening control circuit 27 which includes a analog or digital comparator 28 of the voltage applied to the controller circuit 10 by the conductor 23.
  • a logic element 29 receives on the one hand the signal leaving the comparator 28 and on the other hand the signal S applicable to circuit 10 via terminal 15; the output of logic element 29 is connected on the one hand to a timer call / hold 30a connected to modulator 1, and secondly to a delay device opening 30b to which the conductor 26 is connected.
  • the opening delay member 30b for example of the RC type, makes it possible to adjust the blocking delay of the transistor T2 and therefore the fallout time of the electromagnet.
  • the transistor T3 of the optical component 25 is located so as to allow the discharge of the gate capacitance of transistor T2 when T3 freezes.
  • a Zener Z diode is arranged in parallel to T2 to protect this one.
  • the controller circuit 10 can be a microcontroller with inputs 31 to select the size of the coil of the associated contactor.
  • the microcontroller can also be fitted with double 26.26 'inputs and outputs to control the coils of two contactors mutually associated as reversers.
  • the device shown operates as follows.
  • Coil B is assumed to be initially unpowered, so that the magnetic circuit of the contactor electromagnet is open. To close this circuit magnetic, we close the switch not shown which is associated with terminals 14, this which applies the DC voltage V + to the drain of T2, to the controller circuit 10 and to the converter 20.
  • the transistor of the opening switch 25 is passed through the circuit 10 and the gate of the opening transistor T2 is therefore polarized; it results that T2 is conducting and that, as T1 is also conducting, coil B is supplied with an inrush current, then a holding current lower than the current when the pulse modulator circuit 11 comes into operation.
  • the delay member 30 applies with the predetermined delay a signal to the optotransistor 25 which is blocked.
  • the T2 grid is discharge and T2 hangs. A rapid fallout of the electromagnet is thus obtained.
  • the same quick opening operation can be achieved by switching the signal to low level S presented at terminal 15.
