- the invention relates in particular, although not exclusively, to the field of motorized vehicles where certain equipment must be designed to operate with two supply voltages of different values, typically a low voltage of the order of 12 volts, and a mean voltage of the order of 48 volts.
- FIG. 1 schematically illustrates the assembly made for the validation test relating to the leakage currents of an electrical or electronic device 1 comprising a first connector interface 10 for the 12 Volts, and a second connector interface 11 for the 48 Volts.
- This test consists of connecting all the inputs / outputs of the first connector interface 10 to a first terminal of a DC voltage generator, to connect the inputs of the second connector interface 11 to the second terminal of the DC voltage generator, to apply a voltage of 70 volts by means of the DC voltage generator, and to measure the current by a conventional ammeter.
- the electrical or electronic device 1 is validated if, during this test, the measured current remains less than or equal to 1 microamp (in absolute value).
- the second mass loss test consists in connecting the electrical or electronic device between two 12-volt and 48-volt power supplies, simulating the loss of the 48-volt side earth cable and detecting any damage to the ground cable on the other side. 12 Volts.
- the electrical or electronic device 1 is validated if, during this test, no damage is found after a period of about 30 minutes.

- additional heater is used to start a motor vehicle to warm up the cabin more quickly.
- the low power supply 3 is used for the management and the interface of the module 2 while the higher power supply 4 is used to supply the heating resistors (not shown) contained in the module.
- the higher power supply 4 is used to supply the heating resistors (not shown) contained in the module.
- only the ground of the voltage generator 4 is connected to the module.
- the LIN data input of the module is supplied by the voltage generator 3 and the generator 4 ground.
- Such an architecture could therefore not be used for a 12 Volts / 48 Volts device conforming to the specification mentioned above. above which imposes two separate masses for each supply network.
- the loss of the ground cable of the generator 4 implies that the module 2 can no longer communicate on its LIN data input.
- FIG. 3 schematically represents another known architecture of electrical or electronic device 5 used in vehicles electric cars.
- the device 5 is powered, through two interfaces of connectors 50 and 51, with two very different voltages, a first low voltage of the order of 12 volts, represented by the voltage generator 3, and a second voltage very high, of the order of 400 volts, represented by the voltage generator 6.
- this type of device 5 must necessarily include an isolation transformer 52 to create a galvanic isolation between the power supply 12 Volts and power at 400 Volts.
- the object of the invention is to overcome the above disadvantages by proposing a simple architecture of an electrical or electronic device with two supply voltages, for example 12 volts / 48 volts, which meets the requirements of the specification relating to the presence of two terminals. mass, and which makes it possible to satisfy at least one of the two tests mentioned above.
- the present invention satisfies this objective by proposing an electric or electronic device able to be powered in operation by a first voltage value generated by a first electrical network and by a second voltage value greater than the first voltage value and generated by a first voltage value.
- second electrical network the device comprising:
- a first connector interface capable of being connected, under normal connection conditions to a ground conductor and a voltage conductor of the first electrical network
- each connector interface comprising a ground connection and the ground connections of the two connector interfaces being connected together to form a common ground; and - At least one switch module interposed in series on the common ground, the switch module being adapted to switch to an open position following a change in the connection conditions of the first or the second interface.
- connection conditions are meant the links necessary for the normal operation of the device, that is to say the usual connections of the connectors interfaces to the two electrical networks.
- the switch module can be adapted to switch to an open position in case of loss of the ground conductor of the second power grid
- the switch module can in this case include a positive coefficient of resistance in series on the common ground;
- the switch module comprises a transistor controlled by a current measuring circuit capable of measuring the current flowing on the common ground;
- the switch module can be adapted to switch to an open position as soon as all the inputs / outputs of the first connector interface are connected together;
- the switch module may comprise in this case a MOSFET transistor supplied with voltage by the first electrical network;
- the switch module is associated with a non-return diode capable of preventing any current flow to the first connector interface when the switch module is in the open position.
- FIG. 1 already described above, schematically represents the equivalent electric circuit for a leakage current measurement test of a 12 Volts / 48 Volts device prescribed by the aforementioned specification 148;
- FIG. 2 already described above, schematically illustrates a known architecture for a device using two 12 volt supply voltages;
- FIG. 3 already described above, schematically illustrates a known architecture for a device using a supply voltage of
- FIG. 4 schematically illustrates an exemplary architecture of an electrical or electronic device with two supply voltages, for example 12 volts / 48 volts, in accordance with the present invention.
- FIG. 4 represents an electrical or electronic device 7 according to a possible embodiment of the invention, in the non-limiting context of a dual 12 volts / 48 volts supply.
- This device 7 is represented in its conditions of use, that is to say receiving a first supply voltage of 12 volts of a first network at 12 volts (represented by a voltage generator 3), and a second higher supply voltage, typically of the order of 48 volts, a second network at 48 volts (represented by a voltage generator 8).
- the device 7 comprises:
- a first connector interface 70 capable of being connected to the two terminals of the voltage generator 3, that is to say in practice to the ground conductor GND_12 and to the 12 Volt voltage conductor of the first 12 Volt network;
- a second interface connector 71 adapted to be connected to the two terminals of the voltage generator 8, that is to say in practice to the ground conductor GND_48 and the voltage conductor 48 Volts of the second network to 48 Volts.
- the ground connections of the two connector interfaces 70 and 71 are connected together to form a common ground.
- the device 7 preferably comprises an EMC filtering module 72 (Anglo-Saxon initials set for Electro Magnetic Compatibility) to suppress possible voltage variations, and a module 73 of 12 Volt / 48 Volt interface which integrates the features specific to the device.
- EMC filtering module 72 Anglo-Saxon initials set for Electro Magnetic Compatibility
- module 73 12 Volt / 48 Volt interface which integrates the features specific to the device.
- the module 73 will include the management components and the interface as well as the heating resistors.
- the device 7 further comprises a first switch module 74 interposed in series on the common ground connecting the two ground connections of the connection interfaces 70 and 71, this first switch module 74 being able to be controlled in a closed position as long as the current the through is less than a threshold value of the order of 200 mA approximately, and to switch to the open position if the current passing through it passes above the threshold value.
- This first switch module 74 can be made by the combination of a current measuring circuit, typically composed of an amplifier and a comparator, and a MOSFET transistor controlled to open the ground circuit as soon as the current measurement circuit detects a current greater than the threshold value.
- this switch module 74 will be composed of a resettable fuse, for example a positive temperature coefficient resistor or PTC resistor, of infinite value if the current flowing through the resistor is much greater than the threshold value.
- the device 7 further comprises a second switch module 75 also in series on the common ground, associated with a non-return diode 76.
- the second switch module is for example a MOSFET transistor powered by the 12-volt network, it is that is to say, the source S and the drain D are respectively connected to the ground connection of the connection module 70 and to the ground connection of the connection module 71, and whose gate G receives the voltage 12 volts. In normal operation, this MOSFET transistor is typically in the closed position and its voltage VGS between the gate and the source is then equal to 12 volts.
- the diode 76 will do as for it pass the current in the direction 12 Volts to the module 73 interface 12V / 48 V.
- this second switch module 75 allows the device 7 to meet the leakage current measurement test. Indeed, by carrying out this test (in accordance with the electrical diagram of FIG. 1), all the inputs / outputs of the first connector interface 70 are connected together, so that the voltage VGS becomes zero, even by applying the voltage of 70 volts imposed by the test, and switches the transistor in its open position.
- the non-return diode 76 guarantees that no current can flow in the other direction, that is to say from the second connector interface 71 to the first connector interface 70.
- each of the two switch modules 74 and 75 described above is able to switch to an open position following a modification of the connection conditions of the first interface or the second interface: in particular, for the measurement test leakage currents, the connections of the connector interface 70 are modified compared to normal operation, hence the closure of the switch module 75.
- the loss (disconnection or damaged cable) of the ground cable GN D_48 constitutes a modification of the normal connection conditions of the second interface 71 of connectors, resulting in the closure of the switch module 74.
- the device 7 may of course comprise only one of these switch modules, without departing from the scope of the invention.
- the device obtained meets various points required by the specification 148, while having a simple structure, inexpensive and compact.
