What is a high-voltage DC power supply? Negative high-voltage power supply?

A high-voltage DC power supply usually refers to a power supply with an output voltage greater than 5000 volts. The output voltage of a general high-voltage DC power supply can reach tens of thousands of volts or even hundreds of thousands of volts or even higher. There are two types of DC high-voltage DC power supplies: linearly regulated high-voltage DC power supplies and switch-type regulated high-voltage DC power supplies.

What is a high-voltage DC power supply? Negative high-voltage power supply?

      There are two main technical development directions: the improvement of power supply power, that is, high voltage and high current; reducing the volume of the power supply, that is, high voltage and small volume. Reducing the volume of the power supply is mainly to increase the switching frequency of the power supply. High-power power supplies tend to be larger in size, while small-power power supplies tend to be smaller and smaller in size. In addition, high conversion efficiency, high load, high precision and low wave are also research directions for high-voltage DC power supplies. For high-voltage DC power supplies used for spectral analysis (such as photomultiplier tube power supplies), low ripple is particularly important, and this indicator will directly affect the accuracy of analytical measurements. At low wavelengths, the generated micro-high-voltage DC power supply can be controlled at 0.005%.

      High-voltage DC power supplies are widely used, especially for X-ray machines, lasers, spectrum analysis, non-destructive testing, semiconductor manufacturing equipment, capillary electrophoresis, non-destructive testing, particle injection in semiconductor technology, physical vapor deposition (PVD), nanolithography, ion beam deposition, ion beam assisted deposition, electron beam evaporation, electron beam welding, ion source, DC magnetron reactive sputtering, glass/fabric coating, glow discharge, microwave processing, high voltage condensation test, CRT display test, high voltage cable interference test (PD test), TWT test, H-Pot test. Particle accelerators, free electron lasers, neutron sources, cyclotrons, capacitive induction pulse networks, Marx high-voltage pulse generators, capacitor chargers, microwave heating, RF amplification, nanotechnology applications, electrostatic technology applications, nanofiber electrospinning preparation, core device high-voltage DC power supplies, etc.

What is a negative high-voltage DC power supply?

      The positive ground potential of the DC high-voltage power supply is zero potential, and the negative end of the power supply is negative high voltage. For example, the anode voltage of a picture tube is usually tens of thousands of volts. The negative electrode is connected to the cathode. As zero potential, the output is positive high voltage, connected to the positive electrode; the oscilloscope high voltage in the oscilloscope is to connect the positive electrode to the "ground", to zero potential (add an external deflection signal to the electrode), and the negative high voltage is applied to the cathode.
