What are the specifications of high frequency and high voltage power supplies at home?

The high-frequency and high-voltage power supply is relative to the power frequency high-voltage power supply and the medium-frequency high-voltage power supply. High-frequency high-voltage power supply is a kind of high-voltage switching power supply, its switching frequency is about 50kHz, the intermediate frequency is about 2kHz, and the power frequency is 50 60hz. The advantages of high-frequency and high-voltage power supplies are:

Small size, high precision, fast dynamic response, high technical content, with the soaring of raw materials and technological development, high-frequency and high-voltage power supply is becoming more and more advantageous.

In fact, power frequency high-voltage power supplies have been eliminated in developed countries. The installation quota of high-frequency and high-voltage power supply for electrostatic precipitator should be: 1

The conversion efficiency of high-frequency power supply is high, the conversion efficiency of the ratio of output power to input power of single-phase DC power supply is less than 70%, and the conversion efficiency of the ratio of output power to input power of three-phase high-frequency high-voltage DC power supply reaches 95%, which can improve the conversion efficiency by 25%; 2.The current and voltage of the high-frequency power supply of the electrostatic precipitator are adjustable, and the maximum current and voltage of the high-frequency power supply of the Taixing electrostatic precipitator is 36V20000.

The current power supply is connected to the rectifier module, and then it becomes DC after filtering and three-phase full-wave rectifier, and then connected to the high-frequency inverter circuit to convert DC into high-frequency AC, and finally outputs stable DC after high-frequency transformer, rectifier bridge and filter. The high-frequency switching circuit is mainly composed of rectifier filter circuit, full-bridge conversion circuit, PWM control circuit, voltage stabilization and voltage limiting circuit, current stabilization and current limiting circuit, protection circuit, and auxiliary power supply circuit. After the three-phase grid (or single-phase) voltage is switched on, the rectification filter is carried out, and the obtained smooth DC voltage of 520VDC (single-phase is 300VDC) is supplied to the inverter circuit.

After a period of service life of the dust collector, the efficiency of the dust collector itself decreases, and the secondary voltage and secondary current decrease, which also indicates the reduction of dust removal efficiency. It is recommended that during maintenance, clean the dust of the plates and pole lines, adjust the distance between the pole lines of the plates, and clean the accumulated dust in the insulation chamber at the top of the dust collector, which can improve the filtration efficiency and relatively increase the secondary current and voltage.

Low voltage: less than 1kV, commonly used in residential or small commercial customers to utility distribution lines;

Zhongqing Wang voltage grinding (distribution): between 1kV and 33kV, used for power distribution in urban and suburban areas;

High Clearance Voltage (Transmission): Higher than 33kV, Lower than 230kV;

Ultra-high voltage (transmission): above 230kV, below 800kV for long-distance and very high-performance transmission;

Ultra-high voltage (transmission): above 800kV.

High-voltage power supply, also known as high-voltage generator, generally refers to the power supply with an output voltage of more than 5,000 volts, and the output voltage of the general high-voltage power supply can reach tens of thousands of volts, or even as high as hundreds of thousands of volts or higher.

High voltage power supply, also known as high voltage generator, English: high voltage power supply, generally refers to the output voltage of more than 5,000 volts of power supply, the output voltage of general high voltage power supply can reach tens of thousands of volts, or even up to hundreds of thousands of volts or higher.

The high-voltage power supply we usually refer to generally refers to the DC high-voltage power supply, and the DC high-voltage power supply has two types: linear adjustment high-voltage power supply and switching adjustment high-voltage power supply. There are two main directions for the development of its technology, one is to improve the power of the power supply, that is, high voltage and high currentThe second is to reduce the volume of the power supply, that is, high voltage, small size, and the main reason for reducing the volume of the power supply is to increase the switching frequency of the power supply. High-power power supplies tend to be larger, while small-volume power supplies tend to have less current and lower power.

In addition, high conversion efficiency, high load, high precision, and low ripple are also the research directions of high-voltage power supply designers.

For high-voltage power supplies (e.g. photomultiplier tube power supplies) used for spectral analysis, low ripple is particularly important, this index will directly affect the accuracy of analysis and measurement.
