    Device for air purification and high voltage generation
    The invention relates to devices for air purification consisting of a DC high voltage source and conductive plates or structures which are arranged in a housing or a fastening device and further comprising two devices for generating the required high voltage. The first device for generating a higher voltage from a smaller DC voltage consists of a positive input terminal and a negative input terminal, between which the operating voltage is applied, a positive output terminal and a negative output terminal, between which the output voltage is taken off, a capacitor, at least two magnetically coupled coils, a diode, an active switch, and a voltage multiplier circuit. The second device for generating a higher voltage from a smaller DC voltage also consists of a positive input terminal and a negative input terminal, between which the operating voltage is applied, a positive output terminal and a negative output terminal, between which the output voltage is removed, a capacitor, a Coil, a diode, an active switch, a timer for driving the active switch and a comparator.
    Air purification systems are becoming increasingly important in cities. The fine dust pollution is often very high. But also normal dusts, pollen, fungal spores and the like lead to more and more people to impairments. There is therefore a need for cheap, easy-to-use devices for air purification in the private and commercial sector, especially in old buildings. For new buildings, air purification can be taken into account right from the beginning in the planning of the air conditioning system.
    The device consists of one or more conductive plates or generally of conductive membered structures to which high voltage is applied and one or more conductive plates or of conductive membered structures attached to e.g. Ground potential are placed. For the purpose of binding the dust, one or more of these plates or structures may have e.g. Oil-soaked paper or duster are applied.
    To generate the voltage, a mains-powered rectifier cascade can be used. For safety reasons, an isolating transformer can be connected between the mains connection and the high-voltage cascade. Because only the losses of 1 TI 6 / fh / 20110506
    To cover the circuit and the leakage current of the one or more electrodes, you only need a type with low apparent power. But if you want a completely separate from the electrical system, so we recommend the use of a battery with subsequent charge pump. The charge pump is operated at a fixed frequency and constant duty cycle until the output voltage exceeds the desired value. Then the clock is disabled and the clock starts again when the voltage falls below a certain value. This is easy to do with a comparator with hysteresis. In principle, DC / DC converters which can be used as charge pumps are suitable. For technical reasons, you will prefer converters that do not require a high-side driver. Increasing the output voltage can also be done by converters with transformers (Spenwandler) or tapped coils. Furthermore, charge pumps are also cascadable.
    An interesting alternative for generating the high DC voltage will be described below. To the positive pole of the input voltage source, a parallel circuit of a coil and a capacitor is connected, the second terminals of the capacitor and the coil are connected to the anode of a diode whose cathode to the positive terminal of an active switch (eg collector of a bipolar transistor or drain of a unipolar transistor ) connected is. The negative terminal of the active switch (e.g., emmitor of a bipolar transistor or source of a unipolar transistor) is connected to the negative pole of the operating voltage. To the coil, a second coil is coupled to the output of a voltage doubler circuit or a voltage multiplier circuit is connected. The resulting high voltage is connected to the device for air purification. The function is simple. The active switch is switched on briefly, the capacitor charges itself abruptly and at the same time the current in the coil increases. If the transistor is switched off, the resonant circuit begins to oscillate at the natural frequency of the resonant circuit. The amplitude of the oscillation can be, depending on the quality, a multiple of the operating voltage. By the transformer coupling of the first and second coils, this oscillation is transmitted to the second coil (and can be influenced by the turns ratio of the coils). The connected voltage multiplier stage (voltage multiplier cascade) leads to a further increase in the voltage, which is then available as DC voltage. Due to the loss, the oscillation amplitude decreases and after about ten oscillations, the active switch is again switched on briefly. It makes sense to set the switching process to 2 T16 / fh / 20110506 if the voltage at the capacitor is approximately equal to the supply voltage in order to avoid the sudden charging of the capacitor. It is advantageous in this circuit that the voltage at the output is floating, so you are completely free, which side of the output voltage you ground and thus can be generated a positive or negative voltage. Furthermore, it is also possible to use two secondary windings or a secondary winding with tapping.
    The task of cleaning the air in rooms is erfmdungsgemäß accomplished by the fact that the conductive plates of one or more double-coated copper-clad / n Druckplatte / s consists / s to which the high voltage source is connected, or the conductive structures connected to two of the high voltage source For reasons of safety, one or more plates may be grounded or formations or parts of structures, and the conductive plates or structures may be made of a soft removable layer of cloth, cellulose or paper, which may also be used to better hold the suspended particles out of the air a vegetable oil can be soaked, coated. The device can be supplemented with a fan for forced air transport, or ionizer. But it is also very important that the structures are artistically designed in the form of sculptures or pictures, using conductive paints, colors and materials. According to the invention, the required high voltage can also be generated according to the invention by connecting the first terminal of the first coil and the first terminal of the capacitor to the positive input terminal and connecting the anode of the diode to the respective second terminals, whose cathode is connected to the positive terminal Connected to the active switch and whose negative terminal is connected to the negative input terminal; and to the second coil, the voltage multiplier circuit is connected, the output of which is connected to the first and the second output terminal or connected to a plurality of secondary windings according to further multiplier circuits and connected thereto further output terminals, wherein the clock generator with a constant switching frequency, the much lower is the natural frequency of the resonant circuit formed by the capacitor and the first coil, operates with a constant pulse time and with a two-position controller with hysteresis, which monitors via a voltage divider the voltage at the output, which, as long as the voltage is less than a certain value, clocks, then and when the voltage value falls below a lower threshold again releases the clock or that, the positive input terminal with the coil, the second terminal of the coil with the positive input of the active switch and the anode of the 3 T16 / fh / 20110506
    Diode is connected and the negative terminal of the active switch is connected to the negative input terminal, the cathode of the diode is connected to the capacitor and the positive output terminal, the second terminal of the capacitor is connected to the second terminal of the coil, wherein the clock generator with a constant switching frequency and a constant pulse time works and with a two-position controller with hysteresis, which monitors the voltage across the capacitor via a voltage divider, which, as long as the voltage is less than a certain value, clocks, then turns off and when the voltage falls below a lower threshold again the Clock is free, the first circuit should be mentioned that the active switch is only turned on for a predetermined time in steady-state operation when the voltage across the capacitor reaches approximately the operating voltage. As a result, charge pulses are avoided on the capacitor. Circuit technology that can be realized via a control or release via a comparator.
    The combination of art and technology represents a special added value. Artistic design and technically high-quality air purification do not contradict each other, but complement each other harmoniously. There are no limits when it comes to the choice of material for the artistic design. Whether wood, clay, plastic or metal conductive pastes or paints, the required conductivity can be produced. Panels can also be integrated directly into the wall and thus serve the artistic design of the room with simultaneous use for air purification. Plates can be printed and painted with colors whose conductivity is given. 4 T16 / fh / 20110506
