Definitions

the present invention relates to a voltage multiplier with several impedances or resistance resistors put in series.
It can be used to power discharge tubes of the Argon or Neon type (called cold cathode) or fluorescent tube, laser, small model or for any other use.
cold cathode Argon or Neon type
fluorescent tube laser, small model or for any other use.
the aforementioned devices have the disadvantages of being more expensive economically, heavier in weight, less reliable, if components of equal quality are used, given the quantities of components used, according to the invention are less for a function, and equal result.
the invention aims to remedy these aforementioned drawbacks by creating a supply device having at least two output impedances, one entirely independent of the aure with a large impedance gap.
the method according to the invention uses a voltage multiplier with two resistance levels starting from the AC sector.
multiplier can be executed by a smaller number or more multiplier cells compatible with current and future technology.
This device includes by way of example (see fig.l) the diodes 1-2 -3-4-5-6, capacities 7-8 which are of great value for ensuring, determining and maintaining the discharge current in the tube.
the capacities 9-10 which can be of high value close to the preceding ones, if one wishes to make them support an important function in the discharge current, on the other hand they can be of very low value if one wishes to make them execute the unique priming function; capacities 11-12 which are of very low value are only used for priming the tube.
Resistor 13 is of low value, and serves to limit the intensity during commissioning, the peak current; it can be replaced or seconded by a selfic impedance or resistance to coefficiant of negative temperature or any other means limiting the peak intensity.
the resistor 14 has the function of limiting the peak current in the discharge tube, it is presented by way of example, an ohmic resistor and can be replaced or seconded by an active component, such as a transistor (see Fig. 1)
the regulation cell includes a resistor 15, a Zenner diode 16, a resistor 17, and a transistor 18, which is used to determine the discharge current. (See Fig. 2)
the discharge tubes have the tendency to decrease their internal resistances, when the discharge current increases, this reality can cause unpleasant effects which consist in flashing the lighting at an indefinite frequency, if the choice of the resistance 14 is too low, in general it is of the order of a few hundred Ohmes to a few Kilo-Ohmes.
