Definitions
- the invention relates to devices for generating high voltage, and more particularly to reducing the output voltage of the switching transistor included in such devices.
- the invention is advantageously but not exclusively applicable to the generation of plasma in a gas, using such high voltage generation devices, and in particular the generation of plasma by the electrodes of a spark plug, used for the controlled ignition of an internal combustion engine.
- the principle of the resonant candle resides in the use of a resonant coil-capacitor assembly, the latter consisting of two electrodes (one of which has the base) separated by a dielectric material, such as ceramic.
- This high frequency resonator is generally called “coil-candle”.
- This resonator is powered by a voltage generator capable of delivering a voltage pulse train to the resonator in response to a high frequency control pulse train received on the control electrode of the switching transistor of the voltage pulse generator.
- this pulse generator comprises, in addition to the switching transistor controlled by the high frequency control pulse train, a coil-capacitor assembly connected in parallel and supplied with a medium voltage.
- This pulse voltage generator and the series capacitive inductive resonator constitutes a high-voltage generation device and is commonly called by the person skilled in the art “pseudo-class E amplifier”.
- control of the switching transistor is effected by a high frequency voltage (control pulse train) applied to the gate of the transistor.
- a high frequency voltage control pulse train
- the transistor When the transistor is on, a current flows in the coil while when the transistor is off, the current charges on the one hand the capacitor and on the other hand feeds the coil of the series resonator.
- the drain potential of the transistor is raised.
- This high voltage periodically supplies the series resonator (coil-spark plug) which, thanks to an important quality factor, creates the high voltage able to trigger the sparks.
- Such generators are described in patent applications FR 03-10766, FR 03-10767 and FR 03-10768.
- Pseudo class E amplifiers can also be applied to ultrasonic injection devices.
- the ultrasonic excitation of the piezoelectric injectors requires the generation of a high voltage between 200 and 1800V peak to peak and modulated between 25 and 50 kHz.
- a pseudo class E amplifier requires a control transistor that can support the required power and voltage levels, greatly reducing the diversity of available components.
- An object of the invention is to propose a solution that makes it possible to reduce the voltage delivered at the output of the power transistor while maintaining a sufficient voltage across the series resonator.
- a high voltage generating device comprising a capacitive inductive resonator capable of amplifying a high voltage, means for generating a high frequency control pulse train, a voltage source.
- a capacitor and a voltage generator comprising a switching transistor whose control electrode is connected to the output of the generating means of the high frequency control pulse train, the source of the switching transistor being connected to a ground, the drain of the switching transistor being adapted to supply a voltage pulse train to the capacitive inductive resonator in response to the train of control pulses received on the control electrode of the switching transistor.
- the drain of the switching transistor is connected to the capacitive inductive resonator via an isolation transformer, the isolation transformer being connected in parallel with a capacitor, the isolation transformer being further connected to the source of the capacitor. voltage.
- the primary winding of the isolation transformer may be connected by a terminal to the drain of the control transistor and by another terminal to the voltage source, the primary winding of the isolation transformer being connected in parallel with the capacitor.
- the secondary winding of the isolation transformer can be connected by a terminal to the capacitive inductive resonator and by another terminal to a ground, said ground also being connected to the capacitive inductive resonator.
- the high voltage generating device may comprise a galvanic isolation isolating the primary winding and the secondary winding, the components and mass connected to one winding being isolated from the components and ground connected to the other winding by said galvanic isolation.
- the mass present in the circuit connected to the secondary winding can be distinct and isolated from the mass present in the circuit connected to the primary winding.
- the generating means of the control pulse train may comprise a fixed frequency oscillator.
- the voltage pulse generator GENI comprises a transformer and capacitor transformer set C l connected in parallel, and a switching transistor M l, here formed of an N-channel power MOSFET transistor, controlled on its gate G by a train of control pulses generated here by a fixed frequency oscillator OSC.
- This frequency is a high frequency, typically of the order of a few MHz and greater than 1 MHz.
- the TRANS transformer comprises a primary winding with N l turns and a secondary winding with N2 turns.
- a terminal of the secondary winding is connected to a first terminal of the capacitive inductive resonator RS2 modeled by a resistance R2, inductance L2 and capacitance C2.
- the other terminal of the RS2 series resonator is connected on the one hand to a ground, on the other hand to a resistor R3 connected to the other terminal of the secondary winding.
- the resistor R1 can be either modeling the resistive behavior of the wiring connecting the second terminal of the secondary winding to the ground, or a physical component whose role is to measure the current flowing in the RS2 series resonator. In the latter case, the resistive value of this component will be chosen very low compared to the value of R2, in the resonator RS2, so as not to degrade the performance (overvoltage factor) of the resonator
- a galvanic isolation IG separates the two windings of the TRANS transformer.
- the galvanic isolation IG also separates on one side the components connected to the primary winding and on the other side the components connected to the secondary winding.
- the RS2 series resonator also called capacitive inductive resonator, can be included in a plasma generation plug or in a piezoelectric or ultrasonic injector.
- the natural frequency of the series resonator formed by the inductance L2 and capacitance C2 also has a high resonance frequency, for example greater than 1 MHz, with an overvoltage factor of, for example, between 40 and 200.
- the GENI pulse generator is powered by a DC voltage source DCT delivering a medium voltage, typically less than 1000 volts.
- this voltage source VMT preferably has a limited power so that the energy applied between the electrodes of the spark plug is also limited, for example to 300 mJ by ignition and for safety reasons.
- a 12 volt to Y volt Y converter can be used, which is the voltage supplied by the VMT power supply. It is thus possible to generate the desired DC voltage level from a battery voltage.
- the stability of the DC voltage generated is not a priori a decisive criterion, we can for example provide to use a switching power supply to supply the generator GENI, for its qualities of robustness and simplicity.
- This high voltage typically of the order of several hundred volts periodically supplies the RS2 series resonator, which thanks to a large overvoltage factor, creates the high voltage HT capable of triggering sparks.
- the winding is preferably made with shielded coaxial wire with ground braid to limit high frequency interference.
- the manufacturing constraints can be reduced to take into account the lower frequencies involved.
- the Use of a transformer with respect to an inductor generates several notable advantages.
- the use of a transformer makes it possible to economize a series capacitor situated between the output of the pseudo class E amplifier and the charge of the multi spark spark plug (BME), as well as the common mode filter of the Balun type.
- BME multi spark spark plug
- the use of an isolation transformer removes the DC component of the input signal of the RS2 series resonator, thereby reducing the maximum voltage applied to the cable while maintaining the amplitude of the signal. It follows that the constraints on the insulation of the cable are less stringent than in the case of a pseudo class E amplifier without transformer. The range of usable cables is then greater.
- a pseudo class E amplifier with transformer isolates the capacitance C l and the power supply of the connection cables to the RS2 series resonator.
- a short circuit at these cables or between one of these cables and the ground can not create an electric shock.
- connection cables comprise a ground braid and a shielding molded into the sheath. For increased isolation, one end or both ends of the ground braid may be connected, the return of current through R3 being provided by another conductor.
