High voltage technology

High voltage technology has been widely used in the national economy, industrial technology and scientific and technological research fields, and high voltage engineering is an engineering field with a long history and vitality. The most common and initial application of high voltage technology is in the power industry, in long-distance power transmission, increasing the transmission voltage can effectively reduce transmission losses. In modern industrial technology, high voltage technology is not only applied in the power industry, in many scientific and technological fields outside the power industry are used high voltage technology, such as electrostatic dust removal, industrial desulfurization and denitrification, ozone generation, plasma surface treatment, medical equipment and so on. Similarly, in the field of scientific research and development, the use of high voltage technology is also very much, in some engineering projects, high voltage technology is in a pivotal position, the realization of high voltage power supply determines whether the entire project can be approved, such as high-energy particle accelerator, strong laser generator, high power microwave emitter and so on.

The traditional high voltage technology uses the power frequency boost form, that is, the mains directly through the high ratio transformer boost to get high voltage, now in the high voltage grid power supply and transmission system, high power or even large power large ratio power frequency transformer is still very common, the form of high voltage power supply with easy production, reliable work, long life and other characteristics, But at the same time, the power supply has the disadvantages of large equipment volume, inflexible control and poor voltage stability. Now in industrial technology, switching power supply technology has been very mature, low-voltage switching power supply has been successfully applied to a variety of industries, switching power supply precisely has the advantages of flexible control, small size, constant current, voltage regulation. Thus, the high voltage switching power supply technology is organically combined with the high voltage switching power supply technology. The high voltage switching power supply technology has the advantages of the switching power supply and realizes the high voltage output. Of course, when the high-voltage switching power supply is implemented in the project, it is necessary to apply the design concept of high-voltage engineering and apply the circuit principle of the switching power supply to make the two organically integrate with each other.

The use of switching power supply technology in high voltage engineering, combined with the corresponding automatic control technology, can realize the remote control of high voltage equipment, intelligent control, high-precision control, so that high voltage technology is more flexible and effective in all walks of life. PLC, PLD/EPLD, DSP, microcontroller and industrial computer and other technologies have been successfully used in a variety of switching power supplies, each has distinct characteristics, can achieve different control functions.
