The high frequency pulsed plasma power supply has excellent performance compared with the traditional thyristor-controlled power frequency power supply. It has many significant advantages for example, it has small output ripple, high average voltage and current, small size, light weight, integrated structure, high conversion efficiency and power factor, and uses three-phase balanced power supply which has small impact on the power grid. With these advantages the dust removal efficiency can be greatly improved. It is a revolutionary replacement product of the traditional thyristor power frequency power supply.

The high frequency pulsed plasma power supply independently developed by our company is the advanced high frequency pulsed power supply in China.It is widely used in air purification, electrostatic precipitator, desulfurization and denitrification, plasma application, gas phase deposition, vacuum electronics, microwave communication, laser pumping and other engineering and technical fields.

The high frequency pulsed plasma power supply developed by our company consists of two parts: one is the controller, which controls and monitors the smooth operation of the entire power supply, and the other is the high-voltage power supply, which is used for transformation ratio boost rectification and final output discharge.
