With the development of semiconductor technology, solid-state linear transformer drivers (SSLTDs), of which every stage containing many branches in parallel on the primary side is grounded, can generate high-voltage pulses with high current up to hundreds of Amperes in a few nanoseconds on the secondary side. As one type of pulse adders, the high voltage only appears at the secondary side, which considerably reduces the complexity of SSLTDs. However, the pulse widths are limited by the magnetic saturation of pulsed transformers, and the generated repetitive high-voltage short pulses are suitable for many applications such as wastewater treatment and tumor ablation. In this article, a nine-stage SSLTD was designed, and a prototype was built. Suppression of transient voltage was investigated. Different pulses, including square pulses, triangle pulses, and M-wave pulses, were obtained, and both the rise/fall time and the shapes of pulses can be modulated flexibly through controlling the synchronism of signals for different stages. Pulses with a voltage amplitude of 7.2 kV are obtained over a 100-Ω resistor load. The fastest rise time for high-voltage pulses is 32 ns.

固态线性变压器驱动器基本特性研究


随着半导体技术的发展，固态线性变压器驱动器（SSLTD）的每级包含许多初级侧并联的支路，可以在数秒内产生高达数百安培的高电压脉冲。次级侧的纳秒。作为脉冲加法器的一种，高电压仅出现在次级侧，这大大降低了SSLTD的复杂性。然而，脉冲宽度受到脉冲变压器磁饱和的限制，产生的重复高压短脉冲适用于废水处理和肿瘤消融等许多应用。本文设计了九级 SSLTD，并构建了原型。研究了瞬态电压的抑制。获得了方波脉冲、三角波脉冲、M波脉冲等不同的脉冲，并且通过控制不同阶段信号的同步性，可以灵活地调制脉冲的上升/下降时间和形状。在 100Ω 电阻负载上获得电压幅度为 7.2kV 的脉冲。高压脉冲的最快上升时间为 32 ns。
