IGBT DC Power Supply for Plasma Torch with Isolation Transformer Robust and Reliable Power

Product Detail

IGBT DC Power Supply for Plasma Torch with Isolation Transformer Robust and Reliable Power 




1. Plasma torch power supply applications 


Plasma high voltage rectifiers for plasma torch, which is formed by DC arc discharge, most frequently used for the commercial purposes. There are the two types of plasma torch-transferred and non-transferred.

Thermal Plasma technology can be widely used for industrial applications, such as waste treatment medical and chemical and hazardous waste disposal. Raw material and metal processing, Recovery of valuable metals(Cu, Al, Au etc.), Alternative Energy, Aerospace propulsion, recycling of construction waste, Production of Nano powders. 











Features of plasma torch:


• High temperature

• High efficiency

• High activity

• No pollution

• Gas optional




2. Why choose Green Power rectifiers ?


As China manufacturer, we have 20+ years R&D for plasma heating application, knowing well load characteristics of plasma.




• Technology difficulties of plasma application power supply:
  Multiple plasma load type: from resistive, capacitive, inductive, resistive-capacitive, resistive-inductive load, power supply need to adapt to these load.

• High voltage impulse to power supply: power supply should withstand this impulse, need special circuit design

• Plasma negative resistance characteristic: power supply should match this load feature.
