摘要
采用无感陶瓷电容器作为储能介质,相邻电容器采用宽度为2 cm、厚度为0.2 cm的金属铝条相连接,设计了2.5Ω,200 ns低阻抗Blumlein型脉冲形成网络。理论计算表明,当频率等于2.5 MHz时,相邻电容器之间导线的高频电阻约为3.2 mΩ;基于Pspice仿真软件的模拟结果表明,设计的脉冲形成网络能量传递效率可以达到94.92%;实验研究结果表明,在2.6Ω负载条件下,该脉冲形成网络的电压传递效率约为93.53%,能量传递效率约为93.22%。实验结果与理论分析结果基本吻合。
A Blumlein pulse forming network(PFN) with 2.5 Ω impedance, 200 ns pulse width was designed with low selfinductance ceramic capacitors. The capacitors are connected by aluminium bars with a width of 2 cm, and a thickness of 0.2 cm. The theoretical calculation shows that the lead impedance between adjacent capacitors is about 3.2 mΩ while the frequency is equal to 2.5 MHz. Through the Pspice simulation, 94.92% energy transfer efficiency of the PFN can be achieved. The experimental results, generally consistent with the theoretical analysis, indicate that the voltage transfer efficiency of the PFN is close to 93. 53%, and the energy efficiency is about 93.22% while the load is 2.6 Ω.
