摘要
针对大气压介质阻挡放电材料表面处理应用,提出一种电流源谐振型等离子体驱动源。通过构建并-串联结构的谐振网络,在全功率范围内实现单周期能量传输时间的压缩,从而提高各个功率下的表面处理效果,并推导出一种判断能量压缩状态在全功率范围内稳定性的方法。然后,通过在逆变器上增加旁路辅助电容,建立电流旁路通路,从而实现开关管的零电压开关,保证了电源高效运行,并推导出辅助电容的选取原则。最后,搭建了一台350W电流源谐振型电源样机,实验结果验证了理论分析的正确性,表明电流源并-串联谐振型等离子体驱动源是一种适合于表面处理应用的有效方案。
A current-fed resonant plasma source is proposed for the atmospheric-pressure dielectric-barrier-discharge surface treatment. The energy transfer time in each period is compressed over the full power range by constructing a parallel-series resonant tank, which improves the surface treatment effects at different powers. A method for judging the energy compression stability over the full power range is also developed. And then, by adding bypass auxiliary capacitors in the inverter, the current bypass channels are established. Hence, the power device zero-voltage-switching and the inverter high- efficiency operation were achieved. The auxiliary capacitance selection principle is derived. Finally, a 350W prototype was built. The experimental results verified the accuracy of theoretical analysis. It is shown that the proposed resonant plasma source is an effective solution for the surface treatment.
