利用PSpice软件，在考虑互感的情况下对直线型、L型和U1型结构的脉冲形成网络进行电路仿真，同时采用瞬态场路同步协同仿真方法对5种不同连接结构的脉冲形成网络进行三维建模和仿真，并对这5种不同连接结构的脉冲形成网络进行实验，实验结果显示：5种不同结构脉冲形成网络的输出波形的上升沿约为45 ns；U1，U2型和U3型结构的脉冲形成网络输出脉冲的半高宽分别为166，158和154 ns，且其平顶处存在较大波动。将电路和瞬态场路同步协同方法得到的仿真结果和实验结果进行分析和比较，结果表明：瞬态场路同步协同仿真方法能很好地模拟脉冲形成网络的工作过程和输出波形，实验中的匹配负载和开关电感都要比仿真中的大，U型结构脉冲形成网络有利于实现脉冲功率源系统结构的紧凑化和小型化。

In this paper, in the case of considering the mutual inductance, the linear, L and U1 connecting structures of the pulse forming network are simulated by PSpice software. At the same time, a three-dimensional model of five different connecting structures of pulse forming network are established and simulated with the transient field-circuit synchronous collaborative simulation methodology. Then, the experiments of the PFNs with the five different connecting structures are carried out. The experimental results reveal that the rise time of PFNs with five different connecting structures is about 45 ns, the pulse half-high widths of the PFNs with U1-type, U2-type and U3-type structures are 166 ns, 158 ns and 154 ns, respectively. And the flat-tops of the output waveform are more fluctuant. Finally, the simulation results obtained by the circuit and transient field-circuit synchronous collaborative simulation methods and the experimental results are analyzed and compared. The results show that the working process and output waveform of the pulse forming network are well simulated with the transient field-circuit synchronous collaborative simulation methodology, and the matching load and the switch inductance in the experiment are bigger than that in the simulation, and it is of great significance that the U-type structure of PFN is conducive to the compact structure and miniaturization of the pulsed power source system in engineering applications.
