What Is the Difference Between a High-Voltage DC Power Supply and a Special DC Power Supply?
High voltage DC power supply and special DC power supply both have one thing in common, which is that their voltage is very high, and there are many differences. As a general power supply, high voltage DC power supply has many functions that cannot be replaced by special power supply. Today, we will mainly understand the differences between ordinary high voltage DC power supply and special power supply.
Introduction to High Voltage DC Power Supply
High voltage direct current 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 several hundred watts and several kilowatts, stable or steady. In history, a high-voltage DC power supply was needed to convert three-phase AC or three-phase AC on the market from a high-voltage inverter to high-voltage AC voltage. At this time, the rectifier filter will receive the high-voltage DC power supply.
working principle
A high-voltage direct current power supply generates a strong negative voltage, which is then partially connected to the cathode and partially connected to the anode. A strong electric field is then generated between the cathode and anode, and discharge occurs when the electric field at the pole exceeds the specified force. After a period of time, strong electromagnetic wind was felt around the electric field. When the light becomes dim, 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. D. It combines with ions or electrons and moves to the pole under the action of an electric field. Electrons have a small mass, but they move very quickly, so they are mainly driven by charged particles.
Due to the frequency, volume, and light weight of the power supply, it is quite large and has poor conversion performance and stability. With the development and completeness of energy switch technology, combining high-frequency switch technology with high-voltage power characteristics has become the mainstream of high-voltage direct current energy development.
2, Introduction to Special Power Supply
Special power supply is a special type of power supply. The so-called special is mainly due to the need for a technical indicator to measure the power supply. Unlike traditional power supplies, it is mainly because the output voltage is very high, especially the output current is large or stability is required. It has high requirements for dynamic response and roll wave, or is important for the output voltage or current from the power supply, pulse or other requirements. This makes the development and production of this power supply more specific and rigorous than traditional power supplies. Special power supplies are typically designed for loads or special environments and have a wide range of applications.
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, optoelectronic display, etc. In the fields of national defense and military, special power supplies are mainly used for radar navigation, high-energy physics, plasma physics, and nuclear research.
