摘　　要：Tesla变压器具有电压比高、体积小、重量轻、能量传输效率高和结构紧凑等优点,在重复脉冲源领域应用广泛,但重复频率低是限制其在等离子体应用发展的主要因素。基于一种螺旋线型Tesla变压器,设计了可重复微秒级脉冲发生器,研究了电容等参数对脉冲源输出特性的影响,提出了晶闸管的导通时序对重频脉冲源的控制要求。搭建了大气压等离子体发生装置,研究了不同脉冲重复频率、不同电源电压幅值及不同电极间距对介质阻挡放电特性的影响。研究结果表明:电极距离的缩小和频率与电压的升高都会导致单位放电次数增加,改善放电的均匀性。Tesla transformer has the advantages of high ratio,small size,light weight,high energy transmission effciency and compact structure.It is widely used in the feld of repetitive pulse sources,but its low repetition rate is the main factor limiting its development in plasma applications.In this paper,based on a spiral Tesla transformer,a repetitive microsecond pulse generator is designed.The infuence of parameters such as capacitance on the output characteristics of the pulse source is studied.The control requirements of the thyristor conduction timing for the repetitive pulse source are proposed.An atmospheric pressure plasma generating device was built to study the effects of different pulse repetition frequencies,different power supply voltage amplitudes and different electrode spacings on the dielectric barrier discharge characteristics.The results show that the reduction of electrode distance,the increase of frequency and voltage will increase the number of unit discharges and improve the uniformity of discharge.
