Definitions

  • the invention relates to a control device for regulating and balancing currents for DC / DC converters, particularly in the field of energy storage, for example for charging and discharging batteries.
  • FIG. 1 illustrates a high power DC / DC converter of the prior art comprising n arms each formed of two semiconductor components arranged in series.
  • Each semiconductor component comprises a transistor T 1, for example an insulated gate bipolar transistor ("insulated gate Bipolar transistor" or IGBT) in parallel with a diode Di.
  • the converter is disposed between a storage assembly 11, for example a battery, and a charging voltage source R, the midpoint of each arm, which corresponds to a phase i of the current, being connected to this source of charge voltage. R by means of a smoothing inductance, L1, L2 ... Ln.
  • This converter also comprises a control chain composed of PIDi and PWMi blocks for each current phase i, the current Ii * representing a current setpoint.
  • a PID block illustrated in FIG. 2, is used to regulate a value, that is to say to force a system to follow a given instruction, by performing a closed-loop servocontrol. This monitors the value to be regulated, it is compared to the given instruction, and the difference between them is measured. An output signal is then generated which is proportional to this difference. But this proportional gain is not enough, because the setpoint can be exceeded because of the inertia of the system. Thus, to predict the behavior of the system, the output value is integrated. If the setpoint is exceeded, the integrator forces the system to adapt the output. In addition, this integral gain is not enough, we monitor the slope (derivative) to verify that we do not exceed the setpoint, and in this case, make a correction.
  • a PWM block uses a PWM pulse width modulation, which consists of introducing additional switches at a frequency higher than the fundamental frequency, transforming a voltage into a sequence of slots of fixed amplitude and variable width, a PWM command is performed by comparing a modulating wave low frequency 20 to a wave high frequency carrier 21 of triangular shape, as shown in Figure 3.
  • the pulses S thus generated serve as commands for the switching of the transistors Ti.
  • control chain for each phase of current to be regulated requires a duplication of the control chain as many times as necessary, which leads to a high consumption of resources.
  • FPGA Field Programmable Gate Array
  • programmable logic networks this results in a greater number of logic gates.
  • the invention relates to a device for regulating and balancing currents for DC / DC converters, between a first and a second voltage source, this device comprising:
  • a divider 1 / n receiving the current coming from the summator and delivering a mean current
  • a PWM block receiving the outputs of these summers and delivering n interleaved channels.
  • a regulated average current from the n arms is used.
  • FIG. 1 illustrates a device of the prior art.
  • Figure 2 illustrates a PID block
  • Figure 3 illustrates the operation of a PWM block.
  • FIGS 4 and 5 illustrate the features of the device of the invention.
  • FIGS 6 and 6A illustrate an embodiment of the device of the invention.
  • the device for regulating and balancing the currents for DC / DC converters of the invention illustrated in FIGS. 4 and 5, comprises:
  • step-up (C1, C2 ... Cn) converters connected at input to a voltage source 11 delivering or absorbing energy
  • n inductors L1, L2 ... Ln connected at the input to the output of each of these converters C1, C2 ... Cn, and at the output to a source of charge voltage R delivering or absorbing energy, through of n connections and a summator 12, n current sensors 22 arranged on each of these links,
  • a regulation chain 18 comprising:
  • a divider 1 / n 25 receiving the current from this summator and delivering a mean current
  • a PWM block receiving the outputs of these n summers and delivering n interleaved channels.
  • the average value of the sum of the currents leaving the DC / DC conversion device is regulated, which requires only a single control chain.
  • the balancing of the currents of the n converters of this DC / DC conversion device is done by measuring these outgoing currents and comparing them with the average value (divided by n). Thus the difference obtained is added, via a proportional gain, to the control of the regulation of the average value.
  • This device makes it possible to use only one control chain and to ensure the balancing of the currents.
  • Figures 6 and 6A illustrate a solution tested on a 500 kW demonstrator of energy storage with Li-ion batteries and NaS batteries.
  • the architecture used corresponds to a basic structure comprising a DC / DC converter 30 and a DC / AC converter 31 located between the battery 32 and the AC network 33, three-phase windings 34 and 35 being arranged at the input and at the output, a capacity being arranged between a DC / DC converter and a DC / AC converter.
  • the curves 36 illustrate the currents of two of the three DC / DC converters, and the curve 37 the total current.
