Definitions
- the present invention relates to the field of electric accumulator chargers, in particular for electric or hybrid motor vehicles.
- the invention relates to a method for frequency control of the input voltage of a DC-DC converter for an electric storage battery charger.
- Chargers for electric accumulators, more commonly known as chargers, for electric motor vehicles require large recharging powers, for example up to 22kW in three-phase, or 7kW in single-phase.
- These chargers generally include two stages of power conversion: a first stage of correction of the power factor, better known by its English name Power Factor Correction, generally abbreviated in PFC, ensuring the AC / DC conversion (AC / DC) of the network voltages to a DC bus (DC bus) and a second DC-DC conversion stage, called DCDC, ensuring control of the output current necessary for charging the battery as well as galvanic isolation of the charger thanks to a transformer.
- PFC Power Factor Correction
- DCDC DC-DC conversion stage
- two DC output voltage bus at the terminals of the output capacitors, are coupled to a DCDC converter each.
- the DCDC can in particular be of the LLC type, as shown in FIG. 2, comprising a transformer 22 ensuring galvanic isolation of the charger.
- FIG. 3 represents a simplified diagram of the assembly of the DCDC converter of FIG. 2, comprising a capacitance Cr and two inductances Lr and Lm.
- the input voltage corresponds to the DC direct bus and the output voltage is the battery voltage.
- the gain then corresponds to the ratio of the two voltages.
- the first DCDC mosfet 120 bridge type LLC operates with a duty cycle of 50% and is frequency controlled.
- a frequency command makes it possible to adapt the gain of the DCDC and to adjust the voltage of the DC buses at the charger input to a determined setpoint.
- the frequency can fluctuate for example between 60kHz and 200kHz.
- the transfer function can also be obtained by the so-called “small signal” method which consists in deducing a transfer function from an excitation around a function point, and from the measurement of the DCDC response, such as described in the doctoral thesis of YANG, Bo. Topology investigation of front end DC / DC converter for distributed power System. 2003. Nevertheless, this transfer function is only valid at the operating point considered and becomes obsolete with each change of operating point. It is therefore necessary to recalculate it each time. Also such a solution is relatively complex to implement and costly in computation time.
- the output voltage is imposed by the battery.
- this output voltage varies over a wide range of values, for example between 250V and 430V.
- regulation of the DC voltage at the input is desirable, because it makes it possible to impose a DC voltage across the capacitors, at the output of the PFC.
- the method further comprising:
- control frequency corresponds to said minimum control frequency
- control frequency corresponds to said maximum control frequency
- control frequency corresponds to an average frequency calculated as a function of the difference between the setpoint voltage value and the measured voltage, values of upper and lower error and maximum and minimum command frequency values.
- the control frequency is calculated by applying the following equation: in which the error value corresponds to the difference VDCR-VDCM between the setpoint voltage value and the measured voltage.
- control is at least partially regulated by an open loop regulator.
- open loop regulator e.g., one can refine the calculation of control frequency.
- the command is frequency-regulated by proportional-integral regulation only when the measured voltage is between said upper limit voltage and said lower limit voltage.
- the control can be improved by selectively refining the control frequency calculation when the measured voltage is close to the setpoint voltage.
- the invention also relates to a device for controlling the frequency of a direct current - direct current converter comprising means for implementing the method as described above.
- the invention also relates to a battery charger for electric accumulators comprising:
- FIG. 1 is a schematic view of an electric accumulator charger known from the prior art
- FIG. 2 is a detail view of a DC-DC converter of a charger according to Figure 1;
- FIG. 3 is a simplified diagram of an LLC circuit of a DC-DC converter according to Figure 2;
- FIG. 4a is a schematic representation of the method according to an embodiment of the invention.
- FIG. 4b is a detailed view of a step of calculating the method according to the embodiment of Figure 4a;
- FIG. 5 is a diagrammatic representation of the applied frequency control of the method, with the time on the abscissa and the volts on the ordinate, as a function of the limit voltages, the reference voltage and the measured voltage, of the step of calculation of the method according to the embodiment of FIG. 4a;
- FIG. 6 is a flow diagram of the method implemented according to the embodiment of Figure 4a.
- a charger 1 for electric accumulators 13 connected to a three-phase electric network 10 includes a power factor correction stage 11, also called PFC stage 11, and converters direct current-direct current DCDC 12a and 12b each comprising an inverter 212.
- the three-phase electrical network 10 is mounted to an input filter 14 transmitting filtered input currents to the PFC stage 11.
- two DC voltage buses connected to the terminals of the output capacitors of step PFC 11, are each coupled to a DCDC converter 12a, 12b, connected in output in parallel to a storage battery 13.
- Each DCDC 12a, 12b of which a single copy is shown in Figure 2, includes an input mosfet bridge 120, an LLC circuit 121, of which a simplified equivalent representation is shown in Figure 3, a transformer 22 and an output diode bridge 122.
- the charger 1 further comprises control means 15 of the direct current / direct current converters 12 suitable for implementing a control method 60 according to the invention.
- the control method 60 aims to frequency control the input voltages of the DC-DC converters 12.
- the method for controlling a DC-DC converter comprises a plurality of preliminary steps 61, 62, 63. These preliminary steps 61 -63 are independent of each other.
- the preliminary steps 61 -63 aim to define operating parameters of the process; they can be carried out prior to the implementation of the process, for example during a calibration phase, or dynamically at the start of the process.
- a step 61 is implemented of defining a maximum control frequency value FRMAX and a minimum control frequency value FRMIN, for example here a maximum frequency FRMAX of 200 KHz, and a frequency minimum FRMIN of 60 KHz.
- a step 62 of implementing a set voltage value VDCR is implemented towards which the input voltage must converge.
- VDCR 450V.
- an error zone 51 is defined 63, defined by two error values, a higher error value eps and a lower error value -eps, these two error values making it possible to define a limit voltage value upper VDRC + eps and a lower limit voltage value VDCR - eps.
- the upper eps and lower -eps error values have an equal absolute value, so as to define an error zone around the symmetrical setpoint VDCR voltage value.
- the invention is not limited to this equality of absolute value, and it is possible to provide error values greater eps and lower -eps having a different absolute value.
- the method then implements a step 64 of obtaining a measured value of the input voltage VDCM.
- a step 65 of calculating a control frequency value of the DC-DC converter is then implemented.
- the measured input voltage VDCM is compared with the values of upper limit voltages VDCR + eps and lower limit VDCR - eps.
- control frequency F corresponds to an average frequency FMOY calculated as a function of the difference between the measured voltage and the reference voltage, the values of the upper and lower limit errors and the values of maximum and minimum control frequency.
- This average frequency FMOY is calculated according to the following equation:
- the pair of error parameters -eps, eps makes it possible to define a zone of error close to the VDCR setpoint, in which the control means calculate a frequency FMOY which makes it possible to precisely converge to the VDCR setpoint value.
- VDRC - VDRM error reaches one of the -eps, eps thresholds, a command frequency is calculated to precisely reach the setpoint and cancel the static error.
- the minimum frequency FRMIN OR maximum FRMAX is applied as described by the following logic, to ensure efficient convergence.
- an Integral Proportional Regulator 42 is activated when the measured voltage VDCM is strictly between said upper limit voltage VDCR + eps and said lower limit voltage VDCR - eps. This makes it possible to refine the frequency calculation F to be applied and improves the convergence of the voltage measured over a few volts.
- the output of the first control stage 41 therefore arrives as an open-loop control command called feed-forward e t is added 43 to the results obtained by the PI regulator 42.
