Definitions

  • the invention relates to an inverter with the features of the preamble of claim 1.
  • the object of the invention is therefore to avoid impermissible overvoltages.
  • the solution according to the invention is characterized in an inverter of the type mentioned at the outset by the features of the second part of the main claim.
  • each series resonance circuit has to be assigned such a parallel branch with voltage-dependent resistance.
  • the characteristic of a voltage-dependent resistor has a first range in which practically no current flows up to a certain limit voltage. This is followed by the current-carrying area in which the characteristic curve is to run as steeply as possible: the voltage-dependent resistor therefore blocks practically up to the limit voltage in both directions and has a practically very low resistance for voltages above it. With a corresponding adjustment of the limit voltage of the voltage-dependent resistor to the data of the inverter and its load circuit, it can be achieved that the voltage-dependent resistor works in the current-carrying area when the lamp is ignited.
  • the voltage-dependent resistor is also dimensioned such that it carries practically no current when the lamp has ignited: the series resonant circuit is then damped by the lamp or completely ineffective.
  • the voltage on the components of the load circuit is limited to the lower operating voltage of the lamp.
  • the inverter W is connected via terminals w1, w2 to a step-up converter H, which in turn is fed by an AC voltage network N and which supplies the inverter with a DC voltage. Between the terminals w1, w2 there is a very large storage capacitor C6 and the series connection of the two controllable switches in the form of transistor V1, V2.
  • the load circuit Parallel to the switching path of V1 is the load circuit, which consists of a series connection of a reversing capacitor C1, a discharge lamp E with the heatable electrodes e1, e2, an inductor L and the primary winding t1 of a saturation transformer T; the electrodes e1, e2 of the lamp E are connected in series via a capacitor C, this capacitor C and the inductor L determining the resonance frequency f o .
  • the two transistors V1, V2 are alternately turned on by a control set S, this control set containing secondary windings t2, t3 of the saturation transformer, from which the control voltages for the transistors are derived.
  • the operating frequency f B of the inverter is determined here by the dimensioning of the saturation transformer T in relation to the dimensioning of the inverter and its load circuit; it must always be above the resonance frequency of the load circuit, so that a currentless phase between the blocking of one transistor and the control of the other is ensured.
  • the voltage-dependent resistor R1 forms a parallel branch in series with a capacitor C4, which is connected in parallel with the series circuit comprising the inductor L, the saturation transformer T and the second transistor V2 of the inverter: C4 becomes C over conductive V2 and C1 charged from the storage capacitor C6 and reloaded in the same way when the V1 is conductive as soon as the limit voltage of R1 is exceeded.
  • the monitoring device for current-dependent disconnection of the inverter is connected to the capacitor C4: a thyristor V3 is used for disconnection, which is connected to DC voltage via the electrode e1 and to which a further secondary winding t4 of the saturation transformer T is connected in parallel via a diode D3.
  • the control path of this thyristor is connected via a switching diode D2 to an RC element R3, C5, which is connected in parallel with the aforementioned capacitor C4 via a resistor R2 and a diode D1.
  • thyristor V3 becomes conductive and short-circuits the winding t4, so that the transistors of the inverter no longer receive any control voltages.
  • the ignition capacitor C3, which is also parallel to V3, is short-circuited, the voltage of which initiates the start of the inverter via a switching diode D4. This state remains until the holding circuit of the thyristor is interrupted by replacing the lamp E.
  • the operating frequency can be shifted in the opposite direction up to the limit value f BG with the associated curve KRG.
  • the components must be dimensioned so that the highest operating frequency in question does not exceed this limit value, so that an operating point in the current-carrying region of the characteristic curve of the voltage-dependent resistor R1 is guaranteed.
