Definitions

  • the present invention relates to control gear for lamps, in particular to an electronic ballast for at least one gas discharge lamp, in particular a fluorescent lamp.
  • the input from the prior art known electronic ballasts usually forms a connected to a power supply high-frequency filter, which is connected to a rectifier circuit.
  • the supply voltage directed by the rectifier circuit is supplied to a smoothing circuit for generating an intermediate circuit voltage (bus voltage).
  • An inverter fed with the intermediate circuit voltage finally generates a high-frequency alternating voltage, which is applied to the load circuit with the gas discharge lamp arranged therein.
  • the operation with the high-frequency AC voltage among other things, an increase in the luminous efficiency of the lamp result. By changing the operating frequency is also given the opportunity to operate the lamp in different levels of brightness (dimming).
  • the invention relates in particular to electronic ballasts with a smoothing circuit (English: Power Factor Correction, PFC), which the the Inverter supplied DC link voltage (bus voltage) provides.
  • PFC Power Factor Correction
  • the intermediate circuit voltage is regulated to a predetermined desired value, which is effected by a control circuit arranged within the smoothing circuit. This compares the current value of the intermediate circuit voltage as an actual value with an internally specified value and accordingly controls the energy consumption of the ballast and thus the value of the intermediate circuit voltage.
  • a control of the energy consumption is usually carried out with the aid of a controllable switching element.
  • this switching element of the smoothing circuit can lead to harmonics, which "back" in the connected power supply. This means that the voltage and current at the input of the ballast diverge in phase and distortion occurs, which leads to the generation of harmonics, which can be perceived by the connected network.
  • harmonics in the network can have a disruptive effect, standards usually require that during normal operation of the gas discharge lamp the harmonics generated by an electronic ballast only "re-radiate” into the network below a certain level.
  • the smoothing circuit should therefore be designed so that a divergence of the voltage and the current in terms of their phase is avoided as possible.
  • the present invention has now set itself the task of extending the flexibility of the smoothing circuit (PFC) such that it is particularly fair in terms of requirements for a dimmable electronic ballast.
  • PFC smoothing circuit
  • an electronic ballast for at least one gas discharge lamp, in particular a fluorescent lamp.
  • the ballast is supplied with an input voltage and has a smoothing circuit controlled by an intermediate circuit voltage regulator for generating a regulated DC link voltage and an inverter stored with the DC link voltage. At least one lamp can be connected to the inverter.
  • the ballast external commands such as dimming, can be supplied.
  • the DC link controller has properties that depend on the applied commands. Unlike the EP 1 189 490 A1 If necessary, the properties of the DC link controller are also changed within the same operating state (preheating, ignition, normal operation), in particular if an external dimming value specification changes.
  • the external commands are to be distinguished from the "internal" operating states, according to the EP 1 189 490 A1 different properties of the smoothing circuit cause.
  • a controller can be assigned to the DC link controller, to which the external commands can be supplied and which transmits to the DC link controller dependent setpoints with respect to the dynamic characteristics or other properties of the DC link regulation.
  • setpoints are, for example, values with regard to the DC link voltage, the time constants of the DC link controller and the permissible harmonics (THD).
  • a bidirectional communication can take place between the controller and the DC link controller in which the DC link controller transmits to the controller operating parameters of the smoothing circuit.
  • These operating parameters can be, for example, the type and / or the level of the applied input voltage and / or the intermediate circuit voltage.
  • the controller can be software controlled.
  • the controller can be connected to a memory in which a look-up table (LUT) is stored, which assigns corresponding setpoints for the smoothing circuit to defined external commands, for example dimming values.
  • LUT look-up table
  • the controller can also determine the setpoint values for the DC link control, depending on the external commands, via implemented functions.
  • the characteristics of the DC link regulator may also be adjustable depending on the type and / or the level of the input voltage of the electronic ballast.
  • an electronic ballast (EVG) is provided, in which the DC link controller receives set values for the operation of the smoothing circuit from a software-controlled controller.
  • EMG electronic ballast
  • the addition of the software-controlled controller thus allows a much more flexible design of the electronic ballast in comparison to the prior art, which brings advantages in particular in dimmable but also in non-dimmable ballasts.
  • the invention also relates to an electronic ballast according to claim 1.
  • the invention further relates to lights with such ballasts, to methods for operating an electronic ballast and a computer software program product to support such methods.
  • the invention also expressly relates to a microcontroller, as it can be used in such methods or ballasts.
  • FIG. 1 shown schematic representation of the electronic ballast according to the invention has been on the representation of the rectifier circuit, which is usually formed by a full-bridge rectifier omitted.
  • the rectified mains voltage is supplied to the smoothing circuit, which is formed in the illustrated example by a step-up converter, which consists of an inductor L1, a diode D1, a storage capacitor C1 and a controlled by the DC link voltage regulator 1 switching elements in the form of a field effect transistor S1.
  • the intermediate circuit voltage V z provided by the smoothing circuit is supplied to a load circuit 2 containing the inverter 7 and the load circuit 8 with the gas discharge lamp LA arranged therein, which can be a fluorescent lamp.
  • the intermediate circuit voltage controller 1 which is designed as a digital controller in the example shown, will now be explained in more detail.
  • the current value of the intermediate circuit voltage V z is first detected via the input line 9.
  • the intermediate circuit voltage V z could also be detected indirectly, for example via the input voltage.
  • this analog value of the intermediate circuit voltage V z is converted by an analog-to-digital converter 2 into a digital value u (k).
  • the conversion takes place in each clock cycle of the intermediate circuit voltage regulator 1, wherein the clock is predetermined by a central clock in the form of a fixed-frequency oscillator 3.
  • the clock signals of the clock generator 3 are also supplied to a computing unit 5, which forms the core of the digital intermediate circuit voltage regulator 1, and to a control block 6 for driving the field-effect transistor S1.
  • the arithmetic unit 5 serves to calculate a control value y (k) in each clock cycle, which is transmitted to the control block 6. This converts the control value y (k) into a signal for operating the field-effect transistor S1 and thus controls its turn-on time.
  • the switching through of the field effect transistor S1 takes place at a time at which as no current flows through the diode D1, as a result, the switching losses are reduced.
  • a detection winding L2 which is inductively coupled to the inductance L1 of the boost converter. If the field effect transistor S1 blocks, then the current across the inductance L1 drops continuously until it reaches zero at a certain point in time.
  • This Time is detected by means of the detection winding L2 of the control block L6 and the field effect transistor S1, while avoiding switching losses again switched through.
  • the control value y (k) specifies how long the field effect transistor S1 is turned on. By the duration of the power consumption of the ballast and thus the amount of the provided intermediate circuit voltage V z is determined. However, it is also possible to change its duty cycle as a function of the current control value y (k) instead of the switch-on time of the switch S1.
  • control value y (k) takes place not only on the basis of the current actual value u (k) of the intermediate circuit voltage V z , but also on the basis of the actual values and the control values in the previous clock cycles. Due to the digital properties, the control value y (k) is calculated according to a specific function, ideally after an infinite series. This infinite series consists of series members, which however in the present example are aborted after the third term in order to keep the effort for calculating the control value within an acceptable range.
  • the parameters used to weight the individual row members determine the dynamic behavior of the DC link voltage regulator 1. Accordingly, by using different parameter sets for the control block 6 in calculating the control value y (k), the DC link voltage regulator 1 adapted to different requirements.
  • the arithmetic unit 5 of the DC link regulator 1 is assigned an integrated controller 10, which communicates bidirectionally with the arithmetic unit 5 of the intermediate-time regulator 1 (see reference numeral 11).
  • the controller 10 is connected to a memory 12. Via a digital interface 13, the controller 10 can receive digital commands, such as dimming value specifications, but also, for example, send status messages or error messages to a connected digital bus, for example with the DALI standard.
  • digital commands such as dimming value specifications, but also, for example, send status messages or error messages to a connected digital bus, for example with the DALI standard.
  • the DC link controller 1, the controller 10 with the interface 13 and the memory 12 may be embodied for example as an ASIC.
  • the software-controlled controller 10 thus receives externally supplied digital commands via the interface 13. Furthermore, the arithmetic unit 5 of the DC link regulator 1 can report back status information or operating parameters to it. Typical examples of this feedback from the arithmetic unit 5 of the DC link regulator to the controller 10 are the type and / or level of the applied input voltage and the current value of the intermediate circuit voltage V z .
  • the DC link controller 1 is set via software depending on externally supplied commands, such as dimming values or feedback from DC link controllers.
  • the DC link regulator can be set to the output power of the load circuit containing the lamp.
  • the external default value is in this case, for example, a signal from a controller for the power of the output circuit.
  • This setting is particularly important for dimmable electronic ballasts, which may experience "static" load changes due to variable lamp power compared to non-dimmable electronic ballasts.
  • properties of the smoothing circuit it must be possible for properties of the smoothing circuit to be changed even in an operating phase, in particular during operation of the lamp in the ignited state.
  • T off is the switch-off duration of the switch S1 and corresponding to T on the switch-on of this switch.
  • the controller 10 may also determine these specifications via implemented functions.
