摘要

摘要: 全固态直线变压器驱动源（Solid-state Linear Transformer Driver, SSLTD）因其模块化、固态化、高可靠性和高重频的优势，已成为脉冲功率技术的重要发展方向。本文提出并研制了一种基于层叠 Blumlein 脉冲产生模块（Stacked Blumlein Pulse Generation Module, SBPGM）的紧凑型全固态直线变压器驱动源，并对其进行了实验验证。每个SBPGM 集成了由高压陶瓷电容与 PCB 分布电感构成的混合型脉冲成形网络、串并联 IGBT 开关阵列及隔离驱动电路。所提出的共地双极性充电SBPGM拓扑消除了单个模块内高压隔离的需求，并实现了驱动绝缘电压的均衡，从而显著提升了系统的紧凑性与可靠性。通过对单个SBPGM的电路仿真研究，验证了其在±5.5 kV充电电压下，输出10.8 kV的倍压输出特性以及理想的高压隔离特性。基于该模块构建的30级SSLTD样机在单级充电电压为 ±5 kV、90 Ω水电阻负载的条件下，获得了总输出电压 279 kV的准方波脉冲，且输出电流峰值为3.1 kA，脉宽(FWHM)为 77ns，上升沿(10%～90%)为 22.4 ns，重频50 Hz，对应峰值功率达0.9 GW。

Abstract: Background
Solid-state linear transformer drivers (SSLTDs), featuring modular architecture, solid-state implementation, high reliability, and high repetition-rate capability, have become an important development direction in pulsed-power technology.
Purpose
This paper proposes and develops a compact SSLTD based on a stacked Blumlein pulse generation module (SBPGM) and experimentally validates its performance.
Methods
The SBPGM integrates a hybrid pulse-forming network composed of high-voltage ceramic capacitors and the distributed inductance of PCB traces, a series--parallel IGBT switching array, and inductively isolated gate-driver circuits. The proposed common-ground bipolar-charging SBPGM topology eliminates the need for high-voltage isolation within an individual module and equalizes the driver insulation voltage stress, thereby significantly improving the compactness and reliability of the overall system.
Results
Circuit simulations of a single SBPGM verify the voltage-doubling behavior and the desired high-voltage isolation characteristics, producing a 10.8 kV output under a charging voltage of 5.5 kV. Based on this module, a 30-stage SSLTD prototype is constructed. With a per-stage charging voltage of 5 kV and a 90 Ωwater load, the prototype generates a 279 kV quasi-square pulse with a peak current of 3.1 kA, a pulse width of 77 ns, and a rise time of 22.4 ns at a repetition rate of 50 Hz, corresponding to a peak power of 0.9 GW.
Conclusions
This SSLTD adopts a modular, scalable architecture. The SBPGMs are electrically and mechanically consistent yet independent, enabling straightforward voltage scaling and simplified implementation. Experiments confirm compact size and high power density, demonstrating the potential of high-repetition-rate all-solid-state pulsed-power sources.
