Definitions
- the present invention relates generally to systems for generating plasma between two electrodes of a spark plug, used in particular for radiofrequency ignition control of a gaseous mixture in combustion chambers of an internal combustion engine.
- plasma generation circuits incorporating coils-candles are used to generate multi-filament discharges between their electrodes, to initiate the combustion of the mixture in the chambers of combustion of the engine.
- the multi-spark plug which is mentioned here is described in detail in the following patent applications filed in the name of the applicant FR 03-10766, FR 03-10767 and FR 03-10768.
- the coil-candle is conventionally modeled by a resonator 1, whose resonance frequency F c is greater than 1 MHz, and typically close to 5 MHz.
- the resonator disposed at the level of the spark plug, comprises in series a resistor R, an inductance L and a capacitance C. Ignition electrodes 10 and 12 of the coil-plug are connected across the capacitor C.
- the amplitude across the capacitor C is amplified, making it possible to develop multi-filament discharges between the electrodes of the candle, on distances of the order of one centimeter at high pressure and for peak voltages below 20 kV.
- branched sparks These are referred to as branched sparks, insofar as they involve the simultaneous generation of at least several lines or ionization paths in a given volume, their branches being moreover omnidirectional.
- This radiofrequency ignition application requires the use of a power supply capable of generating voltage pulses, typically of the order of 100 ns, which can reach amplitudes of the order of 1 kV, at a very similar frequency. of the resonant frequency of the radio frequency resonator of the coil-candle. The greater the difference between the resonance frequency of the resonator and the operating frequency of the power supply, the higher the resonator overvoltage coefficient (ratio between the amplitude of its output voltage and its input voltage) is high.
- Figures 2 and 2 bis schematically illustrate such power supplies.
- Figure 2 is further detailed in the patent application FR 03-10767.
- the power supply conventionally implements a so-called "Class E power amplifier” assembly. This type of DC / AC converter makes it possible to create the voltage pulses with the aforementioned characteristics.
- the power supply comprises a power supply circuit 2, respectively having a MOSFET transistor of power M, used as a switch for controlling the commutations at the terminals of the plasma generation resonator 1 intended to be connected. at the output of the supply circuit.
- a control device 5 of the supply circuit generates a control logic signal Vl and applies this signal to the gate of the power MOSFET transistor M at a frequency which must be substantially set to the resonance frequency of the resonator 1.
- the radiofrequency ignition system constituted by the supply circuit 2 and the resonator 1 is powered by a supply voltage Vinter, designed to be applied by the switch M to an output of the supply circuit, at the frequency defined by the control signal Vl.
- the supply voltage Vinter is more precisely provided via a parallel resonant circuit 4, comprising an inductance Lp in parallel with a capacitance Cp, and connected between a capacitance Cb of the supply circuit, charged to the voltage d Vinter power supply, and the drain of the switch M.
- the capacitance Cb, charged to the supply voltage Vinter allows in particular to stabilize the current during an ignition control.
- Figure 2 bis details a variant of the power supply of Figure 2 with a transformer T, allowing galvanic isolation to avoid the secondary mass problems, the inductance Lp then forming the primary transformer.
- This transformer is low gain of the order of 1.5 to 2.
- the parallel resonator 4 transforms the supply voltage Vinter into an amplified voltage Va, corresponding to the supply voltage multiplied by the overvoltage coefficient of the parallel resonator. It is therefore the amplified power supply voltage Va which is applied on the output of the supply circuit at the drain of the switch transistor M.
- the switch M then applies the amplified supply voltage Va to the output of the power supply, at the frequency defined by the control signal Vl, which is sought to make as close as possible to the resonant frequency of the coil-candle. Indeed, during an ignition command, in order to resonate the radiofrequency ignition system and thus maximize the energy transfer to the resonator forming the coil-candle, the latter must be driven substantially at its frequency of resonance.
- the present invention aims to determine this optimal resonance frequency of the radiofrequency coil-plug, in order to achieve optimum control at this resonant frequency of the coil-plug.
- the invention thus proposes a radiofrequency ignition supply device, comprising a supply circuit configured to apply to an output intended to be connected to a plasma generation resonator, a supply voltage at a frequency defined by a control signal provided by a control device of the supply circuit, characterized in that the control device comprises: an interface for receiving a request for determining an optimum control frequency,
- an interface for receiving signals for measuring the voltage across a capacitance of the supply circuit, a module for determining the optimal control frequency, configured to successively supply different control frequencies to the power supply circuit for successive ignition commands during the reception of a request and to determine an optimum control frequency based on measurement signals received by the reception interface.
- the optimal control frequency determining module is configured to determine an optimum control frequency substantially equal to the resonance frequency of the plasma generation resonator.
- the power supply circuit comprises a switch controlled by the control signal and connected to the output.
- the capacity of the supply circuit is charged to the supply voltage at the beginning of each ignition command.
- the module for determining the optimal control frequency is configured to compare two successive values of deviations between a value of the voltage at the terminals of the capacity of the supply at the start of ignition control and a value of the voltage. at the terminals of the power supply capacity at the end of the ignition control, to modify the control frequency in a first direction if the difference between the successive values of deviations has a first sign and determine that the previous control frequency is the optimal control frequency if the difference between the successive values has a second sign.
- the invention also relates to a radiofrequency ignition device comprising a supply device according to any one of the preceding claims and a plasma generation resonator connected to the output of the supply device.
- the plasma generation resonator is adapted to achieve ignition in one of the following implementations: controlled ignition of combustion engine, ignition in a particulate filter, ignition decontamination in an air conditioning system.
- FIG. 1 is a diagram of a resonator modeling a plasma generating radiofrequency coil-candle
- FIG. 2 is a diagram illustrating a power supply used for controlling the resonator of the spark plug coil of FIG. 1;
- FIG. 3 is an example of an algorithm for determining the resonance frequency of the bobbin.
- the optimum control frequency for applying the supply voltage to the plasma generation resonator is a control frequency as close as possible to the resonance frequency of the resonator.
- the control device 5 of the power supply comprises a module 53 for determining the optimum control frequency, when receiving a request for determining an optimum control frequency on an interface 52 provided for in FIG. this effect, to determine and provide this optimal control frequency to a module 54, delivering the control signal Vl at the determined frequency on an output interface 55 of the control device to which is connected the gate of the switch M.
- the switch M then applies the high voltage at the frequency thus defined, at the output of the supply circuit to which the plasma generation resonator is connected.
- T Cb (t) be the voltage across the capacitance Cb as a function of time.
- control signal Vl is applied to the control gate of the switch M, thus allowing the application of the high voltage across the resonator of the coil-spark plug, at the frequency defined by the control signal Vl.
- the aforementioned voltage values used for the calculation of ⁇ T cb are squared.
- the radiofrequency plasma generation resonator 1 is driven at its resonant frequency if and only if:
- the module 53 for determining the optimum control frequency is, during successive ignitions, an electrical measurement of the voltage across the capacitor Cb of the supply at the start of ignition and at the end of ignition, by via an interface 51 for receiving such measurement signals.
- the plasma generating device may comprise a plasma generation resonator adapted to achieve a combustion engine controlled ignition, adapted to achieve ignition in a particulate filter or adapted to perform a decontamination ignition in an air conditioning system.
- FIG. 3 illustrates an exemplary algorithm for determining an optimal control frequency corresponding to the resonance frequency of the resonator.
- a step 101 it is verified that a request to determine the resonant frequency F c of the resonator has been received.
- step 109 a plasma is generated by the resonator 1 using the optimal control frequency for the application of the high voltage on the resonator 1 by the switch M
- the switch M is then controlled to apply to the resonator 1 a voltage suitable for the generation of a plasma, in a manner known per se.
- the capacitance Cb of the power supply is charged to the voltage T ct> (0) intended to be applied by the switch M on the resonator 1 during the step 102 to control an ignition.
- This tension is applied to a predetermined control frequency Ftemp, chosen for example equal to Fmin, corresponding to the minimum driving frequency of the radiofrequency plasma generation resonator.
- Ftemp a predetermined control frequency

- step 106 It is also verified in step 106 that the current value of the control frequency F temp is less than F max, corresponding to the maximum control frequency of the radiofrequency plasma generation resonator. If the value Ftemp does not exceed Fmax, the value of the control frequency Ftemp is increased by a certain frequency step ⁇ F during step 107.
