Definitions
- the present invention relates to a Hochfre ⁇ quenz- and high voltage power supply with retroactive control according to the preamble of claim 1.
- the energisable excimer lamp is equivalent to the circuits of Figure 1, with values of lamp 1 of R of 500 ohms to 3500 ohms and of C of 40 pF to 240 pF. When lamp 2 is off, the values of C are from 20 pF to 65 pF.
- the known feeding technique as shown in FIG. 2, provides an isolating and step-up transformer 3 capable of applying a non-sinusoidal voltage in the range of 4 KV to 14 KV peak to peak and a frequency of 200 KHz to 400 KHz deliver.
- the transformer 3 is usually controlled by the switching module 4 in the double-bridge embodiment, as can be seen in FIG.
- the switching module 4 is in turn controlled by a Kontroll ⁇ unit 5, as is apparent from Figure 2.
- the switching module 4 is a rectifying and
- the step-up transformer 3 must be dimensioned for carrying the load feeding back to the voltage of 4 KV to 14 KV from peak to peak, with particular attention paid to the functional isolation beyond safety.
- the step-up transformer 3 must be dimensioned to bear the loads attributed to the frequency of 200 KHz to 400 KHz and at the same time to the voltage of 4 KV to 14 KV with special attention to reducing the capacitance distributed across the secondary winding.
- the distributed capacitances of the transformer 3 and the connection cable 8 with the lamp 9 complicate the load of the switching module 4, whereby excessive dimensions are required in order to control the parasitic elements which are due to the construction.
- the dimensions of the feeders known type are equal in size of an order of magnitude greater than the proposed invention.
- the weight of the prior art feeders is four times higher than that of the proposed invention in terms of equality of features.
- the object of the present invention is therefore to propose the solution of the problems of the prior art and a highly resistant, safe, and highly insulated dispenser of reduced dimensions. Measures side to the problems of the prior art to be ⁇ .
- the power supply is suitable for feeding excimer lamps in the voltage range from 4 KV to 14 KV peak to peak, in the frequency range from 200 KHz to 400 KHz, with a wave form in continuous operation.
- the power supply is subject to feedback with an output voltage stability not below 3%.
- the power supply accepts a universal power input from
- the transformer has only one safety isolation between the application on the secondary winding and the main current network on the primary winding. He works with voltages in the order of the mains voltage.
- the transformer is not a step-up transformer and has a uniform ratio of turns.
- the effect of the distributed capacity is drastically reduced and the design is in proportion to the transmitted nominal power.
- the clamping effect is obtained by means of a resonance module consisting of an induction unit in series, the distributed capacitance of the connecting cable with the lamp and the capacitance of the lamp itself.
- the changeover module will be sized for the desired power transferred to the load.
- FIG. 3 shows a block diagram of the proposed unit.
- the control module 10 of FIG. 3 generates the periodic waveforms of FIG. 5 necessary to operate the switching module of FIG.
- the control module 10 receives the set point 14 from the detail R4 (FIG. 4) and the voltage feedback 23 from the resonance module 12 of FIG. 3.
- the feedback voltage is smoothed over the network of components D 1, D 2, R 1, R 2, R 3 and C in FIG. 4 and made available to the analog controller 13.
- the analog controller 13 from FIG. 4 processes the error between the set point 14 and the feedback 23 by supplying a voltage signal which is proportional to the operating frequency of the lamp 9.
- This signal controls a voltage-controlled oscillator 15, which in turn generates the signals G1 and G2 from FIG. 5 for the control of the switches Q1, Q2, Q3, Q4 of the switching module 11 from FIG.
- the amplitude E + and E- of the control signals is a function of the type of switches used.
- the ratio of the on-time Ton and off-time Toff of Figure 5 with respect to the control waveform of the switch of the switching module 11 is fixed and uniform.
- the controlled oscillator 15 from FIG. 4 supplies the frequency and voltage information of the lamp to the microcontroller 16 from FIG. 4, which prepares it and transmits it to an externally accessible connecting line 17.
- the controlled oscillator 15 of Figure 4 operates a digital, galvanically isolated external signal with on and off function of the lamp 9 from.
- the switching module 11 from FIG. 6 operates the resonance module 12 from FIG. 3 with the square wave form VS (t) from FIG. 8 with constant amplitude and variable frequency.
- the voltage V has an average of zero and accepts peak values VA + and VA-, as shown in FIG. They originate from the alignment and smoothing module 18 from FIG. 3, which supplies the switching module 11 from FIG. 6 with the continuous supply (VA +) - (VA-), normally of about 400 V.
- the isolation transformer 19 operates via the secondary winding the resonance module 12 from FIG. 3, with the same voltage values VA + and VA- of the primary winding.
- the resonance module 12 from FIG. 3 consists of an induction unit 20, which is normally insulated by a heat-dissipating resin, from the coaxial cable 8 for connection to the lamp 9 and from the lamp 9 itself.
- the induction unit 12 from FIG. 7 effects the sinusoidal feeding of the lamp 9.
- the voltage feedback 23 is applied at the output via a capacitive divider, which is subsequently worked out by the analog circuit from FIG.
- the switching module 11 from FIG. 6 is fed by the alignment and smoothing module 18 from FIG. 3, which converts the mains voltage at the input into a constant DC voltage.
- the rectification and smoothing module 18 of FIG. 3 receives the current in phase with the mains voltage at the input, providing 21 for the automatic correction of the power factor.
