High-voltage DC power supply and special DC power supply have one thing in common, that is, their voltage is very high, and there are many differences. As a common power supply, high-voltage DC power supply has many functions that special power supply cannot replace.
Today we mainly understand the difference between common high-voltage DC power supply and special power supply.
Introduction to high-voltage DC power supply
High-voltage DC power supply, also known as DC high-voltage power supply, is an AC or three-phase power input on the market. The DC voltage is above 1000 volts or tens of thousands of volts, and the power output is usually between hundreds of watts and thousands of watts, stable or stable. Historically, high-voltage DC power supply is required to convert three-phase AC or three-phase AC on the market from high-voltage inverter to high-voltage AC voltage, at which time the rectifier filter will receive high-voltage DC power supply.
Working principle
The high-voltage DC power supply generates a strong negative voltage, and then a part is connected to the cathode and a part is connected to the anode, and then a strong electric field is generated between the cathode and the anode, and discharge occurs when the electric field of the pole exceeds the specified force. After a period of time, a strong electromagnetic wind is felt around the electric field.
When the light dims, you can see a faint purple halo around you. In addition, a large number of particles such as dust resin are formed around the electric field. Combined with ions or electrons, they move to the poles under the action of the electric field. The mass of electrons is small, but it moves very fast, so it is mainly driven by charged particles.
Due to the frequency, volume and light weight of the power supply, it is quite large, and the performance and stability of the conversion are poor. With the development and integrity of energy switching technology, it has become the mainstream of high-voltage DC energy development by combining high-frequency switching technology with high-voltage power characteristics.
Introduction to special power supplies
Special power supplies are special types of power supplies. The so-called special is mainly because a technical indicator is required to measure the power supply, which is different from the traditional power supply, mainly because the output voltage is high, especially the output current is large or stability is required, the requirements for dynamic response and reel waves are high, or the output voltage or current from the power supply is important, pulse pulse or other requirements.
This makes the development and production of this type of power supply more specific and strict than traditional power supplies. Special power supplies are usually designed for loads or special environments and are widely used.
Special power supplies are mainly composed of electroplating electrolysis, anodizing, induction heaters, medical equipment, electrical engineering, electrical testing, ecological dust removal, air purification, food sterilization, laser infrared radiation, photoelectric display, etc. In the field of national defense and military, special power supplies are mainly used in radar navigation, high energy physics, plasma physics and nuclear research.
