Review on the Research Progress of Arc Plasma Power Sources in China

Arc plasma, characterized by its high current density, high energy concentration, and elevated gas enthalpy, is widely utilized in fields such as metallurgy, chemical industry, energy and environmental protection, as well as aerospace. Plasma treatment of solid waste is one of the advanced environmental protection technologies at the international forefront. The rapid development of plasma technology has led to continuous updates and upgrades of arc plasma power sources. This paper provides a comprehensive review of the research progress in arc plasma technology in China, with a particular focus on two key aspects: structure and control methods. The objective is to provide a novel perspective and insights for the international academic community, thereby driving further development in the field of arc plasma power sources. Furthermore, it discusses and analyzes the future development of arc plasma power sources with a focus on achieving higher system reliability, increased power output, environmentally friendly solutions, and intelligent operation.
