脉冲形成网络（PFN）和螺旋脉冲形成线（PFL）是实现长脉冲的两种有效方法。高功率脉冲Transformer是这两种方法中非常重要的一部分。本文介绍了两种广泛应用的高压脉冲变压器Transformer，即空心脉冲变压器Transformer和Tesla高功率脉冲变压器Transformer。两者都不适合水-PFL充电。为了对水-PFL快速有效地充电，设计了一种耦合系数为0.75的特斯拉脉冲Transformer，并进行了实验研究。所设计的Transformer由一次绕组、二次绕组、内外磁芯等组成，一次绕组由铜带绕制而成，二次绕组由铜线绕制而成，铜线沿沿着在锥形尼龙棒上的螺旋槽内。推导了开口磁芯特斯拉Transformer的原、副边电感的计算公式，并对Transformer的主要参数进行了理论计算。此外，通过PSpice软件对Tesla Transformer对PFL充电的过程进行了仿真。Transformer用于强流电子束加速器中的螺旋水-PFL的充电。当初级电压为50 kV时，Transformer可以将水-PFL充电至720 kV，能量转换效率为36%。理论和模拟结果与实验结果吻合较好。Transformer具有结构紧凑、稳定可靠的特点。
Pulse forming network (PFN) and spiral pulse forming line (PFL) are two effective methods to achieve long pulse. The high power pulse transformer is a very important part in the two methods. This article presents two wildly used types of high voltage pulse transformer, which are air-core pulse transformer and Tesla high power pulse transformer for oil-PFL charging. Neither of them is suitable for water-PFL charging. In order to charge the water-PFL quickly and efficiently, a Tesla pulse transformer with coupling coefficient 0.75 is designed and experimentally investigated. The designed transformer consists of primary windings, secondary windings, inside and outside magnetic cores and so on. The primary windings is made from copper strip fastened by supporting case and the secondary windings is made from copper line, which is wound along a spiral groove on a tapered nylon stick. The formulas for calculating the primary and secondary inductances of the Tesla transformer with open magnetic core are deduced, with which the main parameters of the transformer are calculated theoretically. In addition, the process of the Tesla transformer charging the PFL is simulated through the PSpice software. The transformer is employed to charge spiral water-PFL in a high current electron beam accelerator. When the primary voltage is 50 kV, the transformer can charge the water-PFL to 720 kV with an energy conversion efficiency of 36%. The theoretical and simulated results agree well with the experimental results. The transformer is featured by its compactness, stability and reliability.
