Description

Technical Field

[0001] The invention relates to an electronic control system for an electric machine and an electrical assembly comprising such an electronic system and an electric machine. Background Art

[0002] In a known manner, an electronic control system for an electric machine comprises:

[0003] An electronic power module for converting DC current into AC current, the electronic power module comprising:

[0004] The first busbar and the second busbar are used to provide DC current to the electronic power module,

[0005] The third busbar is used to supply power to the phase windings of the rotating motor.

[0006] A control pin that receives a control signal for controlling the electronic power module, and

[0007] The electronic control module is separate from the electronic power module and is configured to generate a control signal.

[0008] In order to provide satisfactory control of an electronic power module, it is important to evaluate the temperature of an electronic power element of the electronic power module, such as a controllable switch of a switching arm. French patent application No. 1855045 proposes to measure this temperature using a temperature sensor, such as a thermistor carried on an electronic circuit card of an electronic control module, the heat of the electronic power element being conducted to the temperature sensor via an electrical conductor connected to one of the busbars or to a control pin. In this type of temperature measurement device, the temperature sensor is at a certain distance from the electronic power element whose temperature needs to be known. Therefore, the accuracy of the temperature measurement is reduced due to the heat losses between the electronic power element and the temperature sensor.

[0009] It has been proposed that temperature sensors can be positioned in electronic power modules, close to the electronic power components. However, the method of manufacturing electronic power modules may make it difficult or even impossible to incorporate temperature sensors into electronic power modules. This is particularly true when the electronic power modules are produced using TML (transfer molded leadframe) technology, in which an electrical insulator is overmolded over the busbars, control pins and electronic power components. The electrical insulator is, for example, a thermosetting resin of the epoxy type.

[0010] It is known to use an interconnector, independent of the electronic power module, for connecting the third busbar of the electronic power module to the phase winding of the rotating electrical machine. French patent application FR3068564 A1 describes such an interconnector. The interconnector comprises a conductive part that electrically connects the third busbar to the phase winding of the rotating electrical machine, and a magnetic core. The magnetic core surrounds the conductive part. The core has a groove in which a Hall effect sensor can be placed. A voltage dependent on the magnetic field is generated by the current flowing in the conductive part. The interconnector may also comprise a housing overmolded on the conductive part and the magnetic core. By using such an interconnector, the electronic power module and its manufacturing process can be simplified. This is because, in particular in the case of electronic power modules produced by the TML method, it is difficult to overmold the housing on the third busbar, which has been bent to receive the magnetic core to be integrated into the overmolding. However, the use of such an interconnector has the disadvantage of being bulky, thus reducing the flow space for cooling air in the electronic control system. In patent application FR3068564 A1, the axis of the magnetic core is parallel to the approximate orientation plane of the electronic power module. Therefore, the interconnector has a thick portion whose thickness is at least equal to the outer diameter of the magnetic core. These thick parts reduce the flow space of cooling air in the electronic control system.

[0011] It is known to connect the control pins directly to the electronic control module, as described in patent application FR3068541 A1. Therefore, the location of the connection of the control pins to the electronic control module is limited by the location of the control pins on the electronic power module. Therefore, the location of the control pin connection can be in the central area of ​​the electronic control module, which has the disadvantage of reducing the space available for positioning the electronic control components of the electronic control module. Summary of the invention

[0012] The present invention seeks to overcome all or some of these disadvantages.

[0013] The present invention relates to an electronic system, comprising:

[0014] An electronic power module for converting DC current into AC current, the electronic power module comprising:

[0015] The first busbar and the second busbar are used to provide DC current to the electronic power module,

[0016] The third busbar is used to supply power to the phase windings of the rotating motor.

[0017] A control pin that receives a control signal for controlling the electronic power module, and

[0018] An electronic control module, separate from the electronic power module and configured to generate the control signal, the electronic control module comprising:

[0019] a first electronic subassembly including at least one first trace and at least one electronic control component electrically connected to the at least one first trace,

[0020] a second electronic subassembly, separate from the first electronic subassembly and comprising electronic control means for generating the control signal and / or electronic measuring means for measuring operating parameters of the electronic power module,

[0021] The second electronic subassembly is connected to the first electronic subassembly through the first control pin.

[0022] By using an electronic control module including such a second electronic subassembly, the electronic control device that generates the control signal for the electronic power module can be brought closer to the electronic power module. Therefore, the length of the electrical connection between the electronic control device and the electronic power module can be shortened. This can significantly reduce the cost of the electronic system. For example, in the case of an electronic power module produced by TML technology, the size of the conductive metal plate, such as the copper plate for manufacturing the various busbars of the electronic power module, can be reduced.

[0023] For example, an example of an embodiment of a first electronic subassembly separated from a second electronic subassembly is produced by providing a first support for the first electronic subassembly and a second support for the second electronic subassembly, the first and second supports being at a distance from each other.

[0024] According to an additional feature of the invention, the electronic measuring device is a current sensor.

[0025] According to an additional feature of the invention, the electronic power module extends in a first plane, and one end of the third busbar is perpendicular to the first plane.

[0026] According to an additional feature of the invention, the current sensor includes a magnetic core having an air gap and a Hall effect sensor located in the air gap to measure the current flowing through a conductor passing through the magnetic core, the third busbar passing through the magnetic core, or the magnetic core capable of having a phase winding of a rotating electric machine passing through it.

[0027] According to an additional feature of the invention, the height of the current sensor along the axis of the core is smaller than its width and length in a plane perpendicular to the axis of the core.

[0028] By using a current sensor whose core is penetrated by a third busbar or a phase winding oriented in a direction perpendicular to the first plane, the overall dimensions in a direction perpendicular to the first plane in which the electronic power module extends can be reduced. Due to the reduction in the overall dimensions, for example, more space can be provided for the cooling air flow, in particular in the case of air-cooled electronic control systems. Thus, better cooling of the electronic control system can be provided.

[0029] According to an additional characteristic of the invention, the electronic measuring device is a temperature sensor.

[0030] By mounting the temperature sensor on the second electronic subassembly, the temperature sensor can be brought closer to the electronic power module. Thus, the accuracy of the temperature measurement can be improved. This improvement is particularly obtained when the temperature sensor is thermally connected to an electrical conductor that electrically connects the electronic power module to the second electronic subassembly. The length of the electrical conductor can be reduced to limit the heat that spreads to the surrounding environment.

[0031] According to additional features of the present invention:

[0032] The second electronic subassembly includes a second trace electrically connected to the first control pin,

[0033] The first electronic subassembly includes an electronic control circuit,

[0034] The first control pin is electrically connected to the electronic control circuit.

[0035] According to additional features of the present invention:

[0036] At least the second control pin is electrically connected to one of the first busbar, the second busbar, the third busbar and the control pin,

[0037] The second trace is electrically connected to the second control pin.

[0038] By electrically connecting the first control pin to the second control pin using the second trace of the second electronic subassembly, the second electronic subassembly can act as an interconnector between the electronic power module and the first electronic subassembly. Thus, the electrical connections to the first electronic subassembly can be positioned in an improved manner. For example, these electrical connections can be located on the peripheral area of ​​the first electronic subassembly so as to increase the available space for the electronic components of the first electronic subassembly.

[0039] According to an additional feature of the present invention, the first control pin is separated from the second trace, and / or the second trace is separated from the second control pin.

[0040] According to an additional feature of the invention, the second electronic subassembly further includes a thermal connection between the second trace and the temperature sensor.

[0041] The thermal connection enables heat to be conducted between the second track and the temperature sensor. This makes it possible to assess the temperature of a component electrically connected to the second track, for example a component of an electronic power module.

[0042] According to an additional feature of the invention, the second electronic subassembly further comprises a housing combining the second track and the electronic control device and / or the electronic measuring device, in particular a housing overmolded thereon.

[0043] According to an additional characteristic of the invention, the second electronic subassembly comprises a circuit card on which the second track is arranged and which carries the control means and / or the measuring means.

[0044] The invention also relates to an electrical component, comprising:

[0045] An electronic system as described above, and

[0046] Rotating motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] Figure 1 An electrical assembly 100 is shown in which the present invention may be implemented.

[0057] The electric assembly 100 is intended, for example, to be installed in a motor vehicle.

[0058] The electrical component 100 firstly has a power supply 102 which is designed to deliver a DC voltage U, for example, between 20 V and 100 V, for example 48 V. The power supply 102 has, for example, a battery.

[0059] The electrical assembly 100 further comprises a rotating electrical machine 130 comprising a plurality of phase windings (not shown) which are intended to have respective phase voltages.

[0060] The electrical assembly 100 also includes an electronics system 104 .

[0061] In the various embodiments shown in the figures, the electronic system 104 is a voltage converter 104. However, in other embodiments not shown, the components may perform different functions.

[0062] The voltage converter 104 is connected between the power source 102 and the motor 130 to perform conversion between the DC voltage U and the phase voltage.

[0063] The voltage converter 104 firstly comprises a positive line 106 and a negative line 108, which are used to be connected to the power source 102 to receive the DC voltage U, wherein the positive line 106 receives a high potential and the negative line 108 receives a low potential. The negative line receives, for example, zero potential and is connected to the ground potential of the motor vehicle.

[0064] The voltage converter 104 further includes at least one electronic power module 110 , which includes one or more phase wires 122 for respectively connecting to one or more phases of the motor 130 to provide their respective phase voltages.

[0065] In the depicted example, the voltage converter 104 includes three electronic power modules 110 , each of which includes two-phase electrical wires 122 connected to two phases of an electric machine 130 .

[0066] More specifically, in the example described, the motor 130 includes two three-phase systems, each of which includes three phases and is used to be electrically phase-shifted by 120° from each other. Preferably, the first phase wires 122 of the electronic power module 110 are respectively connected to the three phases of the first three-phase system, and the second phase wires 122 of the electronic power module 110 are respectively connected to the three phases of the second three-phase system.

[0067] Each electronic power module 110 comprises, for each phase wire 122, a first controllable switch 112 connected between the positive wire 106 and the phase wire 122, and a second controllable switch 114 connected between the phase wire 122 and the negative wire 108. The controllable switches 112, 114 are thus arranged to form a chopper arm, with the phase wire 122 forming a central tap.

[0068] Each controllable switch 112, 114 includes a first and a second main terminal 116, 118 and a control terminal 120, which is used to selectively open and close the controllable switch 112, 114 between its two main terminals 116, 118 according to a control signal applied thereto. The controllable switches 112, 114 are preferably transistors, such as metal oxide semiconductor field effect transistors (MOSFEET), whose gate forms the control terminal 120 and whose drain and source form the main terminals 116, 118, respectively.

[0069] In the example described, the controllable switches 112, 114 each have the form of a plate, which is for example substantially rectangular and has an upper surface and a lower surface. The first main terminal 116 extends on the lower surface, while the second main terminal 118 extends on the upper surface. In addition, the lower surface forms a heat dissipation surface.

[0070] For each electronic power module 110 , the voltage converter 104 also includes a filter capacitor 124 having a first terminal 126 and a second terminal 128 connected to the positive wire 106 and the negative wire 108 , respectively.

[0071] It should be understood that the positive wire 106, the negative wire 108 and the phase wire 122 are rigid components designed to withstand a current of at least 1 A. They preferably have a thickness of at least 1 mm.

[0072] In addition, in the described example, the motor 130 has both the functions of an alternator and a motor. More specifically, the motor vehicle also includes an internal combustion engine (not shown) having an output shaft, to which the motor 130 is connected, for example, by a belt or chain or a gear train (not shown). The internal combustion engine is used to drive the wheels of the motor vehicle through its output shaft. Therefore, during operation as an alternator, the motor supplies electrical energy to the power supply 102 based on the rotation of the output shaft. Then, the voltage converter 104 works as a rectifier. During operation as a motor, the motor drives the output shaft (except driving the internal combustion engine, or replacing the internal combustion engine). Then, the voltage converter 104 works as an inverter.

[0073] The electric machine 130 is located, for example, in a gearbox or a clutch of a motor vehicle, or instead of an alternator.

[0074] Figure 2 , Figure 3 and Figure 4 An electronic system 104 according to a first embodiment is shown.

[0075] The electronic system 104 includes:

[0076] An electronic power module 110 for converting DC current into AC current, the electronic power module 110 comprising:

[0077] The first busbar 206 and the second busbar 208 are used to provide DC current to the electronic power module, and the third busbar 522 is used to supply power to the phase winding 810 of the rotating electrical machine.

[0088] The second electronic subassembly 900 is separate from the first electronic subassembly 700 and includes electronic measuring devices for measuring operating parameters of the electronic power module.

[0089] In other words, the first electronic subassembly 700 includes a first support member, the second electronic subassembly 900 includes a second support member, and the first and second support members are spaced a certain distance from each other.

[0090] The second electronic subassembly 900 is connected to the first electronic subassembly through the first control pin 140 .

[0091] The second electronic subassembly 900 includes a second trace 930 .

[0092] At least the second control pin 160 is electrically connected to one of the first busbar 206 , the second busbar 208 , the third busbar 522 , and the control pin 150 .

[0093] exist Figures 2 to 7 In the illustrated embodiment, a plurality of second control pins 160 are used. One of the second control pins 160 is the control pin 150. Another second control pin 160 is connected to the first bus 206, for example. Another second control pin 160 is connected to the third bus 522, for example.

[0100] The second electronic subassembly 900 may include a second electronic circuit card 410. The second trace 930 is, for example, a metal trace formed on the second electronic circuit card 410.

[0101] The second support member of the second electronic subassembly 900 is, for example, the second electronic circuit card 410 .

[0102] In another embodiment not shown, the second electronic subassembly 900 includes a housing overmolded on the second trace 930. The overmolded housing is made of, for example, epoxy resin. The second electronic subassembly 900 is constructed using TML technology, for example.

[0105] In another embodiment not shown, the first control pin 140 and the second control pin 160 are made integrally with the second trace 930 .

[0106] The electronic measuring device of the second electronic subassembly 900 is, for example, a current sensor 910 .

[0107] The current sensor 910 may include a magnetic core 430 and a Hall effect sensor 440. The magnetic core 430 has an air gap in which the Hall effect sensor 440 is placed to measure the current flowing through the electrical conductor passing through the magnetic core 430.

[0108] The height of the current sensor 910 along the axis of the magnetic core 430 is smaller than its width and length in a plane perpendicular to the axis of the magnetic core 430 .

[0109] The height of the current sensor 910 is, for example, at least twice as large as its width and length.

[0110] The core support 432 may be overmolded onto the core 430. The core support 432 is attached to the second electronic circuit card 410, for example by fastening means 433. The fastening means 433 are for example screws or protrusions of the core support 432, heat crimped onto the second electronic circuit card 410.

[0114] The electronic power module 110 extends in a first plane. The third busbar 522 has an end perpendicular to the first plane. The vertical end of the third busbar 522 is connected to the phase winding 810, which has the same orientation as the end of the third busbar.

[0115] The third busbar 522 and the phase winding 810 are electrically and mechanically connected, for example, by brazing / welding or by crimping (not shown).

[0116] The second electronic subassembly 900 has an orientation parallel to the first plane. The axis of the current sensor 910 is perpendicular to the orientation of the second electronic subassembly 900 .

[0117] Since the height of the current sensor 910 is smaller than its length and its width, a second electronic subassembly 900 with a reduced thickness can be obtained.

[0118] The electronic measuring device of the second electronic subassembly 900 may also be a temperature sensor 450 , such as a thermistor.

[0119] The second electronic subassembly may further include a thermal connection between the second trace 930 and the temperature sensor 450 .

The heat-conducting trace 940 is, for example, soldered to the second trace 930 so that heat can be conducted between the second trace 930 and the heat-conducting trace 940. Figure 4 In one embodiment, the second trace 930 and the thermally conductive trace 940 are formed as one piece. In another embodiment, the second trace 930 and the thermally conductive trace 940 are formed as a single trace.

[0121] Such a temperature sensor 450 enables evaluation of the temperature of the electronic power module 110. The heat generated by the electronic power module 110 is transferred via the second control pin 160 and the second track 930, by thermal conduction, to the thermal connection and the temperature sensor.

[0124] In another embodiment not shown, the second electronic subassembly 900 does not include electronic measuring devices for measuring operating parameters of the electronic power module 110 , but rather includes electronic control devices 920 for generating control signals.

[0125] In another embodiment not shown, the second electronic subassembly 900 includes electronic measuring devices 910 , 450 for measuring operating parameters of the electronic power module 110 , but does not include electronic control devices for generating control signals.

The interconnection module can reduce constraints on the positioning of the electrical connection of the first control pin 140 to the first electronic subassembly 700 compared to the positioning of the second control pin 160. Thus, for example, the electrical connection of the first control pin 140 to the first electronic subassembly 700 may be located outside the first electronic subassembly 700. This location makes it possible to reduce wiring constraints on the first electronic subassembly 700 and increase the available space for electronic components of the first electronic subassembly 700.

[0130] The location of the heat exchanger between the first electronic subassembly 700 and the electronic power module 110 allows not only cooling of the electronic power module 110 as described above, but also cooling of the first electronic subassembly 700. The first electronic subassembly 700 includes a heat dissipation surface. The heat dissipation surface is in thermal contact with the heat exchange surface of the heat sink 502. The thermal contact is achieved, for example, using thermal paste or thermal adhesive.

[0135] In the second embodiment, the heat sink 502 is cooled by exchanging heat with ambient air. The cooling fins 540 on the surface of the heat sink 502 opposite the heat exchange surface between the electronic power module 110 and the heat sink 502 can improve cooling by increasing the surface area for heat exchange with ambient air.

[0136] In the second embodiment, the heat exchanger 502 , the electronic power module 110 , the second electronic subassembly 900 , and the first electronic subassembly 700 are sequentially located in parallel planes.

[0137] The cover 300 attached to the heat sink 502 may be used to protect the electronic power module 110 , the second electronic subassembly 900 , the first electronic subassembly 700 , and connection elements such as the first control pin 140 and the second control pin 160 .

[0138] In a variant embodiment not shown, an opening is formed in the cover to allow air flow to pass between the electronic power module 110 and the first electronic subassembly 700 .

[0139] The low height of the current sensor 910 as described above limits the obstruction of the air passage by the current sensor 910 .

[0140] In another variant embodiment not shown, the first electronic subassembly 700 is supported by a supporting housing which is attached to the heat sink 502 , for example.
