Definitions

  • the neon systems divided into different performance classes and both in terms of voltage level as well as Currents in the neon circle.
  • the invention has for its object a supply circuit for a fluorescent tube system with a high-voltage transformer specify in the lower frequency range which simple and inexpensive and structurally smaller than usual today network-frequency systems must be set up and through which also mentioned variety of transformers can be reduced.
  • the circuit according to the invention is accordingly characterized in that the Supply voltage one from a sinusoidally modulated square wave voltage by filtering AC voltage obtained with a frequency of 300 - 800 Hz is that at the Transformer a fluorescent tube can be connected, and that the transformer is designed is that the supply voltage to a high voltage in the range of 750 V - 15000 V stepped up.
  • the inverter WR is further designed so that the width or duration of the square wave signals is variable. This could e.g. by means of one equipped with transistors Bridge inverter circuit can be achieved. About the Controlling the width of the square wave signals can flow in the circuit can be regulated.
  • the electronic control EST is with a current measurement signal MI fogged up, which is preferably measured on the primary side becomes. Of course, it could also be determined on the secondary side.
  • the electronic regulation EST From the measurement signal MI, the electronic regulation EST generates a control signal S1 for the inverter WR.
  • the control signal S1 determines under among other things, the aforementioned width of the inverter WR Square-wave signals and thus the current flow in the circuit.
  • the EST scheme is advantageous with at least one other Provide input for a control signal S2, which e.g. of Protective devices for the detection of fault conditions such as Open circuit, short circuit, and / or earth fault can originate.
  • a control signal S2 which e.g. of Protective devices for the detection of fault conditions such as Open circuit, short circuit, and / or earth fault can originate.
  • one or more could also be on the control Outputs are provided, at which one for the operating state representative information signal IS is available.
  • the electronic regulation as a whole, as well as the aforementioned inputs and Outputs can be analog or digital.
