Definitions
- the field of the invention is that of power supply devices for electrical loads, for example equipment on board an aircraft.
- the invention relates more particularly to a control circuit for a switch of an inverter arm.
- An inverter arm of a device for supplying an electrical load typically consists of a series arrangement of a first switch and a second switch whose midpoint is connected to the load.
- the first switch and the second switch thus form a switch on the upper side of the arm and a switch on the lower side of the arm.
- Each switch may comprise at least one power semiconductor component, for example a wide-gap transistor of the SiC or GaN type which has a lower gate threshold voltage than that of the silicon-based components.
- the gate-source voltage reached due to the overvoltage is higher than the threshold voltage of the high-side transistor, it may turn it on and lead to a short circuit of the inverter arm, the two switches high-side and side low being then initiated at the same time.
- the gate-drain capacitance of the high side component is discharged and the current flowing through the gate loop produces a negative voltage on the gate.
- the negative voltage may be lower than the minimum allowable gate-source voltage which repeatedly damages and prematurely ages the component.
- FIG. 1 An example of these transient phenomena is represented in FIG. 1.
- the upper curve represents the drain-source voltage of the low-side transistor V S WL while the lower curve represents the gate-source voltage of the low-side transistor ⁇ Zg SL .
- the negative overvoltage is for example capable of causing a gate-source voltage of -9V where the minimum authorized voltage is of the order of -10V for components with a wide GaN gap for example. This minimum voltage can be exceeded when several components are arranged in parallel.
- the positive overvoltage is itself, for example, likely to cause a gate-source voltage of 1.7 V where the threshold voltage of a GaN-based component is between 1.2 and 1.5 V, d 'where a risk of short-circuiting the arm of the inverter by the transition of the high-side transistor to the on state.
- a first solution proposed for example in N. Idir, R. Bausiere, and JJ Francchaud, “Active gate voltage control of turn-on di/dt and turn-off dv/dt in insulated gate transistors”, IEEE Transactions on Power Electronics , flight. 21, No. 4, p. 849H855, Jul. 2006, doi: 10.1109/TPEL.2007.876895, is to increase the value of the gate resistor placed between the output of the transistor control circuit and the gate of the transistor.
- This solution makes it possible to reduce the switching speed expressed in dV/dt and therefore the undesirable overvoltages on the gate-source voltage of the transistor.
- this solution leads to an increase in switching losses.
- a third solution proposed for example in E. Aeloiza, A. Kadavelugu, and R. Rodrigues, “Novel Bipolar Active Miller Clamp for Parallel SiC MOSFET Power Modules”, in 2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018, p . 40112407, doi:10.1109/ECCE.2018.8558216, consists of the addition of an active Miller clamp circuit consisting of a transistor, a resistor and a capacitor on each transistor of the switch, allowing to reduce the level of the gate-source voltage in the transient phases.
- This active Miller clamp circuit is in practice only required on one of the inverter arm switches. However, it is necessary to provide as many active clamp circuits as there are transistors in parallel forming the switch considered.
- the object of the invention is to limit, or even eliminate, the effects of all the transient phenomena mentioned above without requiring a circuit dedicated to each transistor of a plurality of transistors arranged in parallel to form a switch. It proposes for this purpose a control circuit for a first switch comprising at least one transistor, the first switch being arranged in series with a second switch in an inverter arm of a power supply device intended to supply a load connected at the midpoint of the series arrangement of the first switch and the second switch.
- the control circuit is configured to adjust the gate-source voltage of the at least one transistor of the first switch according to a control scheme comprising, successively and during a period of deactivation of the first switch, the reduction of said gate-source voltage source in a time window including the activation of the second switch and the increase of said gate-source voltage in a time window including the deactivation of the second switch.
- this circuit comprises three first selectively controllable transistors for applying one of three gate voltages to the gate of the at least one transistor and three second selectively controllable transistors for applying the one of three source-to-source voltages of the at least one transistor;
- the three source voltages include a negative voltage, a neutral voltage and a first transient voltage and the three gate voltages include a positive voltage, the neutral voltage and a second transient voltage;
- it comprises a control unit configured to control the first three transistors and the three second transistors so that: o in a period of activation of the first switch, the positive voltage is applied to the gate of the at least one transistor and the neutral voltage is applied to the source of the at least one transistor; o in the deactivation period of the first switch, outside the time window including the deactivation of the second switch and the time window including the activation of the second switch, the neutral voltage is applied to the gate of the at least one transistor and the negative voltage is applied to the source of the at least one transistor; o
- FIG. 1 already discussed above provides an example of transient overvoltages likely to appear due to crosstalk between the high side and low side switches of an inverter arm of the state of the art;
- FIG. 2 is a diagram of an inverter arm equipped with control circuits according to the invention;
- FIG. 3 is a diagram of a control circuit according to the invention.
- FIG. 4 shows examples of timing diagrams of the control of the various transistors of the control circuit of Figure 2;
- FIG. 5 provides an example of transient overvoltages likely to appear due to crosstalk between the high side and low side switches of an inverter arm provided with a control circuit according to the invention.
- FIG. 2 shows an inverter arm of an electric power supply device intended to supply a load connected to the midpoint Pm of a series arrangement of a first switch SW1 and a second switch SW2.
- the first switch SW1 forms the low side switch of the inverter arm
- the second switch SW2 forms the high side switch of the inverter arm.
- Each of these switches SW1, SW2 is driven by a control circuit 10_1, 10_2 of gate driver type.
- Each of these circuits 10_l, 10_2 amplifies and adapts the gate-source voltage level of the transistor(s) making up the corresponding switch SW1, SW2 to control the opening and closing of the switch at a given frequency. , by means of a gate voltage command Comd_G1, Comd_G2 and a source voltage command Comd_S1, Comd_S2. Together, these circuits 10_1, 10_2 form a control circuit for the up and down switches of the inverter arm.
- the first and second switches SW1 and SW2 are for example wide-gap semiconductor transistor switches based on SiC or GaN. For high power applications, transistors in parallel are used in order to obtain the desired power.
- the invention relates to a control circuit 10 for a first switch, for example the switch SW1.
- This first switch comprises at least one transistor which comprises a drain D, a source S and a gate G.
- a first switch composed of several transistors in parallel, for example two transistors T1, T2 arranged in parallel, whose drains, sources and gates are respectively at the same potential.
- the second switch comprises at least one transistor, for example several transistors in parallel.
- control circuit 10 is not only in charge of controlling the opening and closing of the first switch SW1 at a given frequency but is also configured to reduce the transient stresses on the gates of the transistors of the first switch SW1, thereby improving the reliability of the power supply device.
- the control circuit 10 is more particularly configured to allow adjustment of the gate-source voltage of the transistors of the first switch in a timely manner by means of a gate voltage command Comd_G and a source voltage command Comd_S.
- control circuit 10 is configured to adjust the gate-source voltage of the transistors of the first switch according to a control scheme comprising, during a period of deactivation of the first switch, the increase of said gate-source voltage in a time window including the deactivation of the second switch and the reduction of said gate-source voltage in a time window including the activation of the second switch.
- control circuit 10 can be configured to adjust the gate-source voltage of the transistor(s) of the second switch according to a diagram of control comprising, during a period of deactivation of the second switch, the increase of the said gate-source voltage in a time window including the deactivation of the first switch and the decrease of the said gate-source voltage in a time window including the activation of the first switch.
- the control circuit 10 therefore makes it possible to prevent the gate-source voltage in the first switch from falling below the minimum authorized voltage. The risk of damaging the transistors of the first switch is thus reduced.
- the control circuit 10 therefore makes it possible to prevent the gate-source voltage in the first switch from exceeding the threshold voltage. The risk of a short-circuit current appearing is therefore reduced.
- the control circuit 10 may comprise three first transistors S1, S2 and S6 selectively controllable via respective commands Comd_S1, Comd_S2 and Comd_S6 to apply one of three gate voltages to the gate of the transistors of the first switch and three second transistors S3, S4 and S5 selectively controllable via respective commands Comd_S3, Comd_S4 and Comd_S5 to apply one of three source voltages to the source of the transistors of the first switch.
- Transistors S1-S6 are so-called low current signal transistors. They are referenced to different voltage potentials.
- the three source voltages comprise a negative voltage N to which the transistor S3 is referenced, a neutral voltage Gnd to which the transistor S4 is referenced and a first transient state voltage MCI to which the transistor S5 is referenced.
- the three gate voltages for their part comprise a positive voltage P to which the transistor S1 is referenced, the neutral voltage Gnd to which the transistor S2 is referenced and a second transient state voltage MC2 to which the transistor S6 is referenced.
- the control circuit 10 further comprises a control unit 20 configured to control the first three transistors S1, S2 and S6 and the three second transistors S3, S4 and S5 by delivering to them the respective commands Comd_S1, Comd_S2 and Comd_S6 on the one hand and Comd_S3, Comd_S4 and Comd_S5 on the other hand.
- a control unit 20 configured to control the first three transistors S1, S2 and S6 and the three second transistors S3, S4 and S5 by delivering to them the respective commands Comd_S1, Comd_S2 and Comd_S6 on the one hand and Comd_S3, Comd_S4 and Comd_S5 on the other hand.
- FIG. 4 represents timing diagrams of these various commands in accordance with the invention which make it possible to control the gate-source voltage ⁇ Zg SL of the transistors of the first switch (in solid lines) and the gate-source voltage Vg SH of the transistors of the second switch (in dotted lines) as a function of the activation/deactivation sequence of the first and second switches of the inverter arm. It emerges that the driver unit 20 controls the transistors S1-S6 of the control circuit 10 of FIG. 3 as follows.
- the positive voltage P is applied to the gate of the transistors of the first switch and the neutral voltage Gnd is applied to the source of the transistors of the first switch.
- Transistors SI and S4 are therefore on, the others being off, between t 4 and t 5 .
- the neutral voltage Gnd is applied to the gate of the transistors of the first switch and the negative voltage N is applied to the source of the transistors of the first switch.
- Transistors S2 and S3 are therefore on, the others being blocked, before ti, between ts and t 4 , between ts and t 6 and after t 8 .
- the second transient state voltage MC2 is applied to the gate of the transistors of the first switch and the neutral voltage Gnd is applied to the source of the first switch.
- Transistors S4 and S6 are therefore on, the others being blocked, between ti and t 3 .
- the gate-source voltage of the transistors of the first switch is thus raised between ti and t 3 , making it possible to limit the negative excursion of this voltage when the negative overvoltage caused by the deactivation at time t 2 of the second switch occurs.
- the voltage MC2 is therefore chosen to be greater than the negative voltage N and preferably such that, the gate-source voltage in the first switch being brought to MC2-Gnd, the transient negative overvoltage does not drive this gate-source voltage below the voltage minimum allowed.
- the value of the second transient state voltage MC2 can correspond to that of the neutral voltage Gnd, this choice being advantageous because the level Gnd is already available and it is therefore not necessary to generate a reference level specific voltage for transistor S6.
- the second transient state voltage MC2 is applied to the gate of the transistors of the first switch and the first transient state voltage MCI is applied to the source of the transistors of the first switch.
- Transistors S5 and S6 are therefore controlled in the on state, the others in the off state, between t 6 and t 8 .
- the gate-source voltage in the first switch is thus lowered between t 6 and t 8 , limiting the positive excursion of this voltage when the positive overvoltage caused by the activation of the second switch at time t 7 occurs.
- the voltages MCI and MC2 are chosen such that the difference MC2-MC1 is less than the negative voltage N and preferably such that when the gate-source voltage in the first switch is brought to MC2-MC1, the transient positive overvoltage does not lead not this gate-source voltage above the threshold voltage Vth, threshold voltage which depends on the technology of the transistors used to make the switch.
- the second transient state voltage MC2 advantageously corresponds to the neutral voltage Gnd and the amplitude of the first transient state voltage MCI is greater than that of the negative voltage N.
- the MCI voltage is limited by the negative voltage applicable on the gate of the transistor which depends on the transistor technology.
- the gate-source voltage of the transistor of the first switch SW1 is applied according to a control diagram comprising, successively and during a period of deactivation [t5-t12] of the first switch, the reduction of said gate-source voltage in a time window [t6-t8] including the activation [at t7] of the second switch and the increase of said gate-source voltage in a time window [t9-tll] including the deactivation [at t10 ] of the second switch.
- control circuit 10 may further comprise a power supply unit 30 which typically provides an electrical power supply isolated from the control circuit.
- the power supply unit is powered by a supply voltage Valim and is configured to deliver the positive voltage P and the negative voltage N.
- the control circuit may further comprise a voltage regulator 40 connected to the power supply unit 30 and configured to deliver the first transient state voltage MCI and the second transient state voltage MC2 from the supply voltage Valim.
- the first transient state voltage MCI and the second transient state voltage MC2 can be adjusted or modified by controlling the voltage regulator 40 by a control signal Comd_reg delivered by the control unit 20.
- the control circuit 10 is particularly simple in design, requiring only a simple control of six signal transistors referenced to different voltage potentials from the isolated power supply II is also inexpensive in terms of number of components. to be integrated, the same circuit simultaneously controlling all the transistors in parallel of the switch concerned.
- the invention is not limited to the control circuit described above but also extends to the control method implemented by this circuit as well as to a computer program comprising instructions for the implementation of this method.
- the invention also extends to a power supply device intended to supply a load connected to the midpoint of a series arrangement of a first switch and a second switch in an inverter arm, said device comprising the circuit control previously described.
- the first switch may comprise a transistor or else a plurality of transistors in parallel, the gate-source voltages of which are controlled by the control circuit previously described.
- the invention also extends to an aircraft equipped with such a supply device.
