Definitions
- the invention relates to a circuit arrangement for operating high-pressure discharge lamps according to the preamble of claim 1, a pulse ignition device and a high-pressure discharge lamp with a pulse ignition device and a method for operating a high-pressure discharge lamp.
- the laid-open specification WO 98/18297 describes a push-pull converter which acts on a load circuit and a pulse ignition device galvanically separated therefrom with high-frequency alternating voltage via a transformer.
- a high-pressure discharge lamp is connected in the load circuit.
- the pulse ignition device supplies high-voltage pulses to an auxiliary ignition electrode of the high-pressure discharge lamp during the ignition phase.
- the object of the invention to provide a generic circuit arrangement with an improved voltage supply for the pulse ignition device. len. Furthermore, the circuit arrangement according to the invention is intended to ensure high-frequency operation of the high-pressure discharge lamp with alternating voltages in the megahertz range and reliable ignition of the gas discharge in the lamp.
- the circuit arrangement according to the invention for operating high-pressure discharge lamps has a voltage converter for generating an AC voltage and a transformer connected to it or designed as part of the voltage converter, the secondary winding of which feeds a load circuit which is provided with connections for a high-pressure discharge lamp and for the ignition voltage output of a pulse ignition device, and a series resonance circuit, which is provided for the voltage supply of the pulse ignition device during the ignition phase of the high-pressure discharge lamp.
- an ignition transformer with a lower winding ratio between the secondary and primary winding and a correspondingly reduced inductance can be used for the pulse ignition device in order to provide the required ignition voltage for the high-pressure discharge lamp.
- the reduced inductance of the ignition transformer has the advantage that after the gas discharge in the high-pressure discharge lamp has been ignited, a significantly reduced voltage drop occurs in the secondary winding of the ignition transformer through which the lamp current flows, and thus the losses in the transformer at the voltage output of the voltage converter and in the electronic components of the voltage converter can be significantly reduced.
- the aforementioned series resonance circuit therefore enables the combination of a voltage converter, which is comparatively high operating frequencies are designed significantly above 100 kilohertz, with a pulse ignition device, the ignition transformer of which is connected directly in the load circuit supplied by the voltage converter and which, as described in the laid-open specification WO 98/18297, are not electrically isolated from the load circuit got to.
- the topology of the circuit arrangement can thereby be considerably simplified.
- an auxiliary ignition electrode can be dispensed with in the high-pressure discharge lamp.
- the invention can be applied particularly advantageously to a single-stage voltage converter, in particular a voltage converter designed as a current-fed push-pull converter or as a class E converter, which does not generate an intermediate circuit voltage.
- the circuit topology of these aforementioned single-stage voltage converters is comparatively simple and therefore inexpensive.
- the aforementioned series resonant circuit is connected to the secondary winding of the transformer and, when a high-pressure discharge lamp is connected, is connected in parallel to the discharge path of the high-pressure discharge lamp.
- a higher voltage is generated for the pulse ignition device on the components of the series resonance circuit than in the secondary winding of the transformer if the switching frequency of the voltage converter during the ignition phase of the high-pressure discharge lamp is close to the resonance frequency of the series resonance circuit.
- the series resonance circuit is short-circuited by the now conductive discharge path of the high-pressure discharge lamp and the pulse ignition device is thereby deactivated.
- the series resonance circuit is connected to the voltage converter on the primary side of the transformer.
- the resonance inductance of the series resonance circuit is preferably designed as an autotransformer, the secondary winding of which can be connected to the voltage input of a pulse ignition device.
- the deactivation of the pulse ignition device after the ignition phase of the high-pressure discharge lamp has ended can be done in a simple manner by a change, preferably an increase, in the Switching frequency of the voltage converter can be brought about.
- the switching frequency of the voltage converter is close to the resonance frequency of the series resonance circuit.
- a capacitor is advantageously arranged in the load circuit, which is connected in series with the pulse ignition device connected to the secondary winding of the ignition transformer and whose capacity is dimensioned such that it is suitable for the pulse ignition device generated ignition pulses essentially represents a short circuit and, after the gas discharge in the high-pressure discharge lamp has been ignited, partially compensates for the inductance of the ignition transformer through which the lamp current flows.
- This capacitor can advantageously also be designed as a component of the series resonant circuit.
- the series resonant circuit is designed according to an advantageous embodiment of the invention as part of a pulse ignition device, which, separate from the other components of the operating device of the high-pressure discharge lamp, is accommodated in the lamp base of the high-pressure discharge lamp.
- a pulse ignition device which, separate from the other components of the operating device of the high-pressure discharge lamp, is accommodated in the lamp base of the high-pressure discharge lamp.
- all high-voltage components are arranged in the lamp base, so that the interface between the operating device, which contains the voltage converter with the transformer at its voltage output, and the high-pressure discharge lamp is only subjected to a comparatively low voltage of less than 100 volts.
- This interface therefore does not require high-voltage insulation, but only shields the high-frequency AC voltage in order to ensure sufficient electromagnetic compatibility of the operating device and the lamp.
- this is achieved in a known manner by means of grounded, metallic housings or shields and coaxial cables, the shielding braid of which is also grounded.
- the pulse ignition device according to the invention therefore also has a series resonance circuit which is connected to its voltage input and is used to increase the resonance of the supply voltage provided at the voltage input during the ignition phase.
- a voltage-multiplying cascade circuit can also be used in the circuit arrangement or pulse ignition device in order to provide a higher input voltage than the induction voltage generated by the secondary winding of the transformer for the pulse ignition device.
- the variant with the series resonance circuit has the advantage over that with the cascade circuit that it does not require any switching means for deactivating the pulse ignition device.
- the voltage-multiplying cascade circuit is advantageously supplied with energy either directly from the voltage converter or from the secondary winding of the transformer at the voltage output of the push-pull converter. If the voltage-multiplying cascade circuit is used in combination with the series resonant circuit, then the voltage input of the cascade circuit is connected in parallel to a resonant circuit component and its voltage output is connected to the voltage input of the pulse ignition device.
- a symmetrical voltage doubling circuit can be used in the circuit arrangement or pulse ignition device in order to provide a higher input voltage than the induction voltage generated by the secondary winding of the transformer for the pulse ignition device.
- This symmetrical voltage doubling circuit can also be used in combination with the series resonance circuit described above.
- the symmetrical voltage doubling circuit has the advantage of an approximately symmetrical current consumption during the positive and negative half-wave of the supply voltage and avoids an asymmetrical magnetic modulation of the core of the transformer at the voltage output of the voltage converter.
- the symmetrical voltage doubling circuit is advantageously supplied with energy either directly from the voltage converter or from the secondary winding of the transformer at the voltage output of the push-pull converter. If the symmetrical voltage doubling circuit is used in combination with the series resonance circuit, then the voltage input of the symmetrical voltage doubling circuit is connected in parallel to a resonance circuit component and its voltage output is connected to the voltage input of the pulse ignition device.
- the method according to the invention for operating a high-discharge lamp by means of a voltage converter and a pulse ignition device is characterized in that an increase in the supply voltage for the pulse ignition device is carried out during the ignition phase of the high-pressure discharge lamp with the aid of a series resonant circuit operated near its resonance frequency or by means of a voltage-multiplying cascade circuit ,
- the mode of operation according to the invention enables reliable high-frequency operation of the high-pressure discharge lamp with alternating current frequencies which are far above the acoustic resonances of the discharge medium within the high-pressure discharge lamp.
- the mode of operation according to the invention can ensure that, on the one hand, a sufficiently high ignition voltage is generated during the ignition phase of the high-pressure discharge lamp and, on the other hand, after the ignition phase has ended during lamp operation, the secondary winding of the ignition transformer through which the high-frequency lamp current flows does not cause unacceptably high power losses in the circuit arrangement .
- the voltage converter is advantageously operated at a switching frequency close to the resonance frequency of the series resonance circuit in order to provide a resonance-excessive supply voltage for the pulse ignition device.
- the switching frequency of the switching means of the voltage converter preferably increases a frequency significantly above the resonance frequency of the series resonance circuit to thereby deactivate the pulse ignition device.
