Definitions
- the present invention relates to a secondary resonant circuit.
- the present invention relates to a secondary resonant circuit and to a contactless power transmission device by inductive coupling with resonance, in particular for charging or recharging a battery of a motor vehicle or any type of vehicle, land, air, or maritime, propelled by electrical energy.
- a problem with this type of solution is that to transmit a satisfactory level of power, in particular several kW, it is necessary to operate at high frequencies, in particular of the order of 85 kHz or more, for the resonant frequency of each resonant sub-circuit.
- this type of solution requires operating at a short distance between the resonant elements located at the source and the load.
- the subject of the invention is thus a secondary resonant circuit for carrying out, in a recharging mode, contactless power transmission by inductive coupling with resonance, with a primary resonant circuit comprising at least a first capacitor and a first inductor, this power transmission being directed towards the resistive load coupled to the secondary resonant circuit, this secondary resonant circuit comprising:
- decoupling assembly comprising a rectifier arranged to provide a direct voltage to provide recharging power to the resistive load, and an impedance adaptation assembly which is arranged to vary the equivalent impedance on the input of this impedance matching assembly, independently of the impedance of the resistive load at the output of this impedance matching assembly.
- the equivalent impedance on the input of the impedance matching assembly is represented by the ratio V/l where V is the voltage across the impedance matching assembly and I is the intensity of the current which crosses it.
- the invention thus makes it possible to achieve contactless power transmission by inductive coupling with low frequency resonance, unlike the prior art, thus overcoming the aforementioned drawbacks.
- the use of an impedance matching assembly makes it possible to increase the transmitted power, which is all the more favorable in contactless transfer by inductive coupling with low frequency resonance. We thus benefit from a simple and effective solution to increase the transmitted power.

Such an arrangement allows the value of the capacitance of the second capacitor to be independent of the aforementioned coupling coefficient k and to further increase the power transfer.
- the secondary circuit may be devoid of controlled variable inductance, this variable inductance being arranged to be controlled so as to activate a parametric amplification effect of the current in the secondary circuit.
- this series connection can be directly received on the alternating input of the decoupling assembly of the secondary circuit.

- the first capacitor and the first inductor are for example connected in series.
- the decoupling assembly can comprise two arms mounted in parallel, each arm comprising two switches controllable in series, which are for example MOS transistors, and one of the arms can switch at the frequency of the power transmitted from the primary circuit and with a duty cycle of 50%, and the other arm can switch at a frequency higher than that of the power transmitted from the primary circuit, for example at a frequency equal to or greater than 5 times or 10 times the frequency of the power transmitted from the primary circuit, and with a duty cycle modulated according to the measured alternating current and the voltage on the alternating input of the decoupling assembly.

- the secondary resonant circuit 5 serves to carry out, in a recharging mode, a contactless power transmission by inductive coupling to resonance, with the primary resonant circuit 3, this power transmission being directed towards the resistive load 2 coupled to the circuit secondary resonant 5, this resistive load 2 having an equivalent active impedance.
- the secondary resonant circuit 5 comprises: - a second capacitor Cs of value Cs and a second inductance Ls of value Ls, magnetically and partially coupled to the first capacitor Cp and the first inductance Lp,
- decoupling assembly 10 arranged to decouple the equivalent impedance of the resistive load 2 from the charging power.

- the impedance adaptation assembly 10 of Figure 3 is arranged to vary the equivalent impedance RRef across the terminals of the alternating input, defined between the two midpoints of the arms, independently of the impedance of the resistive load at the output of this assembly 10.
- the equivalent impedance RRef is represented by the ratio V/l where V is the voltage across the alternating input, and I the intensity of the current on this alternating input.
- RRef has for example a value between 5'Q and 15'Q.
- this configuration being determined in particular by at least one of: the position of the secondary resonant circuit 5 with respect to the primary resonant circuit 3 and/or the power level to be transmitted and/or the voltage across the battery, RRef can have a fixed value and this value is for example in the aforementioned range. From one charging configuration to another, for example in the event of a greater distance between the primary resonant circuit 3 and the secondary resonant circuit 5 and/or to take into account the aging of the system, the value of RRef can be modified , remaining in particular in the aforementioned range.
