Definitions
- the invention relates to a method and a circuit arrangement for operating a high-pressure discharge lamp according to the preamble of the main claim and the independent claim, wherein the high-pressure discharge ⁇ lamp is operated by an inverter with a rectangular lamp current having a positive phase with positive current flow and has a negative phase with negati ⁇ ven current flow, and the inverter is controlled by a control device.
- High pressure discharge lamps are often operated with a low frequency square wave current to simulate DC operation. This mode of operation is also referred to as "wobble DC operation".
- the frequency of the rectangular current of low frequency is thereby higher by a maximum of one power than the input network frequency. In principle, therefore, there is a DC operation of the high-pressure discharge lamp, but the lamp current is reversed regularly in order to load the lamp electrodes evenly.
- the solution of the object with respect to the method is accomplished by a method for operating a high-pressure discharge lamp, in which the Hochlichentla ⁇ tion lamp is operated by an inverter with a rectangular lamp current, which is a positive Phase with positive current flow and a negative phase with negative current flow, and the inverter is controlled by a control arrangement, which is characterized by the following steps:
- the rectangular air stream has preferential ⁇ , a frequency less than 500 Hz, in particular less than 110Hz up.
- the lamp is virtually rubbed with a DC current, and the electrode load is uniform and minimal.
- the reference variable of a lamp power or the rectangular lamp current for the control arrangement is preferably the same for both phases. This will be the
- the lamp is regulated to the same power in each phase, resulting in a uniform electrode load. [10] If the lamp power or rechteckförmi- calculated gen lamp current value representing the crizanord ⁇ voltage from the input voltage of the inverter, the input current of the inverter, the voltage of the high pressure discharge lamp as well as a correction factor, the complex lamp current measurement can be omitted, and yet the Lamp power can be calculated with sufficient accuracy.
- a period of time is preferably a period of time between lms and a few seconds, in particular between 5 ms and 50 ms ⁇ sondere long between the following requirements set value of both phases. This allows a slow and cost-effective control can be realized, the low Flickerne Trent shows in operation.
- the solution of the object with respect to the circuit arrangement is accomplished by a circuit arrangement for operating a high-pressure discharge lamp having an inverter for operating the high-pressure discharge lamp, which generates a low-frequency rectangular lamp current, wherein the rectangular lamp current ⁇ a positive phase with positive current flow and a negative phase with negative current flow, and the inverter is controlled by a control arrangement, wherein the control arrangement controls the positive phase and the negative phase separately.
- the reference variable of a lamp power or the rectangular lamp current for the control arrangement is preferably the same for both phases. This will be the
- the lamp is regulated to the same power in each phase, resulting in a uniform electrode load.
- the complex lamp current measurement can be omitted, and nevertheless the lamp power can be calculated with sufficient accuracy.
- control arrangement determines a value representing the lamp power or the rectangular lamp current individually in each phase, and generates a control value specification for each phase on the basis of the measured value.
- control arrangement can generate a sufficiently accurate control value specification for each phase with little effort.
- control arrangement preferably stores in each case a value representing the lamp power or the rectangular lamp current in separate memory cells belonging to the two phases.
- the control arrangement now generates preferably by means of the stored values for each phase individually a manipulated variable specification, which is then output to the inverter.
- the control arrangement generates the manipulated variable specifications preferably at a distance between lms and few
- the frequency of the manipulated variable specifications is preferably at least one power less than the frequency of the rectangular lamp current.
- the control arrangement preferably has a digital controller with a microcontroller.
- the control device according to the invention can be implemented as pure soft ⁇ ware, which saves costs.
- Fig. 1 is a schematic representation of a circuit ⁇ arrangement, which carries out the inventive method.
- FIG 2 shows the schematic drive voltages of the switching transistors of the full bridge, which are controlled by the control unit.
- Fig. 1 shows a schematic circuit diagram of a circuit arrangement which carries out the method according to the invention.
- the circuit has a change ⁇ judge 30 with all parts that are needed for normal operation on. Additional components, such as Zünddros ⁇ sel, ignition capacitor, driver circuits, etc., which are necessary for a start of a high-pressure discharge lamp 5 and conceivable other operating conditions have been omitted for reasons of clarity.
- the inverter 30 consists of a full bridge with 2 parallel half bridges 33 and 35, each having two switching transistors Ql, Q2 and Q3, Q4.
- the switching transistors Q1-Q4 have antiparallel freewheeling diodes D1-D4.
- a series circuit of the high pressure discharge lamp 5 and a lamp inductor Li is connected.
- a capacitor C 2 is connected between the connection point of the high-pressure ⁇ discharge lamp 5 and the lamp inductor Li and the Ver ⁇ connection point of the lower full-bridge transistors Q2 and Q4, which is referred to below as point 7, a capacitor C 2 is connected.
- an input capacitor C1 is connected between the upper input El, which is at the same potential as point 6, and the lower input E2, which is at the same potential as point 8, an input capacitor C1 is connected.
- a current measuring resistor R is connected ⁇ s.
- the inverter 30 is controlled by a control unit
- the control unit 20 measures the input voltage of the inverter 30, that is, the voltage between
- Point 6 and point 7. This is a strong RC-filtering used to hide disturbances and short-term fluctuations of the input voltage of the inverter 30.
- the control unit 20 also measures the voltage across the current sense resistor R s , which is equivalent to the current through the inverter 30. This value is measured individually in the positive phase of the rectangular lamp current and in the negative phase of the rectangular lamp current. Since the full-bridge rectifier of the alternating ⁇ 30, as will be explained later, has step-down properties, the rectangular lamps ⁇ current is a factor of the current through the full bridge. For each measurement, the control unit 20 stores the current value in separate memory cells 210, 211 belonging to the individual phases.
- the control unit 20 calculates under Zu Vietnamesenah ⁇ me the stored current values individually for each phase, the power of the inverter 30 and are each a setting value for Ql and Q2.
- the control values are not recalculated for each low-frequency full wave, but are recalculated only at every nth low frequency full wave, n can assume a value between 5 and several hundred.
- the manipulated variable settings are thus output to the inverter at a time interval of lms to a few seconds.
- the manipulated variable specification can under certain circumstances also be output only every 2-3 seconds. Because of the regulation between a positive half-wave and negative half-wave and these half-waves are controlled separately, a very slow and therefore cost-effective control can be used without operating the lamp asymmetrically. A DC component in the lamp current is so sure vermie ⁇ .
- the control of the inverter 30 is made so that the transistors of the full bridge are driven with a low-frequency square-wave voltage.
- the drive voltage never ⁇ derfrequenten of the transistors Ql and Q2 a high frequency drive voltage is superimposed.
- the second half-bridge 35 of the full bridge 30 is thereby driven single ⁇ Lich with a lower square-wave voltage.
- the high-frequency superposition can be a Puls shimmerenmo ⁇ dulation or other suitable control.
- a low-frequency operation here is the operation with a frequency considered, which is generally a maximum of one power above the input network frequency.
- the frequency of the low-frequency operation is preferably between 50 Hz and 900 Hz.
- the high-frequency operation consequently, the operation is deemed having a frequency which is at least higher by a power than the frequency of never ⁇ derfrequenten operation.
- the frequency of the high-frequency operation is preferably between 3 kHz and 120 kHz
- FIG. 2 shows the schematic drive voltages of the switching transistors Q1-Q4 of the inverter 30, which are controlled by the control unit 20.
- the Tran ⁇ transistors Q3 and Q4 of the half-bridge 35 are driven with a low-frequency voltage, so that they are completely switched through in each half-wave respectively.
- the transistors are switched complementary to produce a positive and a negative current phase through the high ⁇ pressure discharge lamp.
- the transistors Ql and Q2 of the half bridge 33 are also operated by a never ⁇ derfrequenten voltage.
- This low-frequency voltage is additionally superimposed by a high-frequency square-wave voltage, as can be seen from FIG.
- the high-frequency superimposition or drive voltage can be generated by a pulse width modulation or another suitable method.
- Q3 is turned on, Q2 is driven by a high frequency voltage.
- Ql and Q4 are off.
- Q4 is on, Ql is driven by a high-frequency voltage.
- Q2 and Q3 are off.
