Composed of two parts:
1. Control cabinet: frequency conversion, pulse modulation, and power control system;
2. High voltage generator: boosts, rectifies, and outputs high-voltage pulse current.
Application Scenarios:
D. Removal of green smoke: Green smoke consists of small particles, usually between 1 micron and 10 microns in diameter. This is the case with green smoke from smoking. Ordinary DC power supply cannot charge it, while Aputon Power utilizes the high energy of high voltage pulsed DC power supply to negatively charge it, which is deposited on the anode tube wall under the action of electric field force to achieve the effect of removing green smoke. Green smoke from metal drawing plants, chemical plants, heat treatment plants, tobacco plants, asphalt plants, etc. can be removed.
A. Plasma deodorization method: Ionization + advanced electrochemical oxidation method to remove various industrial odors.
B. Removing White Smoke: White smoke is actually a mixture of haze, fog droplets and particulate matter. Exhaust gas humidity is too saturated, ordinary pure DC power supply will be ignited and can not work properly. Plasma power supply is a pure pulse square wave power supply, which will not ignite in the environment of oversaturated humidity and work stably under high voltage; the pulse power supply has large energy and can capture droplets and dust as small as 1 micron, so it can remove white smoke.
C. Excluding yellow smoke: Yellow smoke refers to the use of nitric acid in industrial production. Nitric acid is extremely unstable and decomposes to produce nitrogen dioxide in a brownish-red color, also known as yellow smoke. A Noah plasma power source with an energy of 20eV undergoes advanced electrochemical oxidation to produce NO3. NO3 dissolves in water to form weakly acidic nitric acid, which adsorbs as droplets on the anode. It is neutralized by spraying alkaline water to clean the field. The yellow smoke has been eliminated.
E.Dust Removal: High voltage pulsed DC power supply with unique breakthrough corona sealing and anti-corona function.
F. Other industries with special purposes:
(1) The high-frequency, high-voltage pulsed DC power supply plays a vital role in the X-ray generation process. It is mainly used to provide high voltage to the cathode and anode of the X-ray tube. At high voltages, the electrons at the cathode gain enough energy to rapidly strike the anode target material. When these high-speed electrons suddenly decelerate, some of their kinetic energy is released in the form of X-rays, which can be used in a variety of applications such as medical imaging and industrial testing.
(2) High-frequency high-voltage pulsed DC power supply has the following main functions in electropuncture disinfection and sterilization. High-frequency high-voltage pulse can generate a strong electric field. This strong electric field can change the transmembrane potential of the microbial cell membrane, thus forming small holes, the so-called electroporation. When the permeability of the cell membrane is altered, the internal equilibrium of the microorganism is disrupted, leading to the leakage of the cell contents and causing the death of the microorganism. At the same time, the pulsed electric field can also make the charged particles inside the microbial cells move violently under the action of the electric field and collide with each other, destroying the intracellular structure, such as ribosomes, nucleic acids and other biological macromolecules, so as to achieve the effect of disinfection and sterilization.
(3) High-frequency, high-voltage pulsed DC power supplies can also be used for ion implantation processes in chip production.

Performance comparison between ordinary power frequency
DC power supply and Noah plasma power supply:
Serial number | Project Name | Ordinary industrial frequency DC power supply | Aputon Plasma Power Supply |
1 | Grid input side | Two-phase, unbalanced | Three-phase, balanced |
2 | Output power mode | DC, large ripple | 80kHz pulsed DC square wave; high-frequency narrow pulse, the higher the power supply frequency, the smaller the electric field capacitive reactance, and the greater the energy injected into the electrostatic precipitator by the power supply. |
3 | Output voltage fluctuation | 30% | 1% |
4 | Spark off time | Thyristor control, 10ms | IGBT switch control + PWM pulse width modulation, 25us |
5 | Power efficiency | <75% | >95% |
6 | Power Factor | <78% | >93% |
7 | Power supply volume and weight | Larger | Smaller |
8 | Energy consumption | high | Very low, saving 80% compared to industrial frequency power supply |
9 | Control type | Thyristor voltage regulation control millisecond control | PWM width modulation, microsecond response speed |
10 | Flashover characteristics | It cannot respond quickly to flashover shock, and the output current takes a long time to gradually drop to zero. | The device automatically tracks the critical point of the electric field breakdown voltage by adjusting the pulse width. The electric field is not prone to flashover, achieving optimal power output. |
11 | Arc ignition | When ignition is on, the power is turned off directly | First, some pulses are turned off, and the power supply remains in working state. After the pulses are turned off, the energy decreases, the arc disappears, and the power supply resumes normal operation. The power supply is only turned off for protection if an arc is generated . |
12 | Electric water jet cleaning | No water spraying with electricity | The electrostatic field can be cleaned by spraying water without stopping the power supply |
13 | Anti-corona situation | Industrial frequency DC power supply generates back corona. After the back corona phenomenon occurs, the dust removal efficiency drops significantly. | The plasma power supply does not produce back corona. The instantaneous high voltage of the pulse wave makes it easier to charge the dust, so the dust removal efficiency is greatly improved. |
14 | Dust collection and purification efficiency | During the process of particle charging by DC corona, as the charge of particles increases, potential barrier energy is generated on the particle surface. Charging occurs only when electrons with kinetic energy greater than or sufficient to overcome the surface potential barrier energy of charged particles collide with particles. Electrons with kinetic energy lower than the surface potential barrier energy of charged particles cannot reach the particle surface and are not charged. When charging reaches a certain stage, the charging speed of dust decreases, which affects the charge of dust and causes low dust removal efficiency. | 30% higher efficiency than ordinary DC. In pulse discharge, due to the high instantaneous potential, the energy obtained by electrons from the electric field is very large, generating high-energy electrons. These high-energy electrons collide with neutral gas molecules to decompose or excite neutral molecules to generate more electrons. At this time, the charged particles in the electric field space are mainly electrons, and the corona current is formed by electron transmission. The charge of fly ash particles is mainly electron charge.
The electron charging mechanism of fly ash in the corona field of pulse discharge is mainly based on the electric field charge and kinetic energy diffusion charge of electrons. The electron charge of fly ash particles is not only related to the electric field strength, but also to the degree of thermal motion of electrons (i.e., the kinetic energy of electrons).
During the pulse period, the density of excited electrons in a unit space is very large and the energy is very high. The high-energy electrons are sufficient to overcome this potential barrier and bombard the surface of fly ash particles to make the particle charge exceed the limit of saturated electric field charge, thereby obtaining a faster approach speed and improving dust removal efficiency. |
15 | Adaptability to working conditions | Some scenes are available | Available in all scenarios |
16 | Yellow smoke removal effect | Ordinary DC has no yellow smoke removal function |
We have done an experiment where copper was added to nitric acid to produce NO2 yellow smoke. In the absence of alkali neutralization spraying, the yellow smoke could be purified .
|
17 | Dust removal efficiency and power consumption | It can collect dust but consumes a lot of electricity. A set of dust removal power supply consumes 50~60 kWh of electricity per hour. | The dust removal efficiency is increased by 30%. A set of dust removal power supply consumes about 10 kWh of electricity per hour. It saves 40kw of electricity per hour, 960kw per day, 28,800kw per month, and 288,000kw per year (calculated based on 10 months ). If the electricity fee is 0.5 yuan per kWh, it saves 144,000 yuan per year. |
18 | Capture of high resistivity and fine dust | Difference | Good. Capture of high resistivity dust, capture of fine dust. The emission of fine dust is a key indicator affecting the dust emission concentration of electrostatic precipitator. The instantaneous high-intensity electric field corona generated by high-frequency double narrow pulse power supply greatly improves the capture of PM2.5 and below particles. |
19 | Transformer Features | Ordinary DC is an industrial frequency transformer with oil temperature of 100~120 degrees. | The high-frequency transformer is small in size and the temperature rise does not exceed 25K. |
20 | Machine structure and protection |
| The transformer and control cabinet can be installed together or separately. The display screen is installed in the control room and connected via RS485 communication or optical fiber . |
