Abstract

The invention belongs to the technical field of impulse power and particularly relates to an electromagnetic induction type self-triggering LTD. The LTD is composed of three parts of a triggering induction cavity module, an ordinary induction cavity module and a self-triggering induction cavity module. The three parts are connected in series through a secondary center convergence bar successively, the triggering induction cavity module forms several front stages of a channel of LTDs, the self-triggering induction cavity module forms several rear stages of the channel of the LTDs, and during working, only first stage induction cavity modules of the induction cavity module which are triggered synchronously are needed to be triggered, the whole channel of the LTDs can be triggered. According to the drive source, extra signals needed to be triggered are few, and the synchronization problem of extra signal triggering is not needed to be considered; the system reliability is high; extra triggering units are not needed, the size is small, the structure is compact, and the cost is low; and good expandability is provided, the number of the induction cavity module can be freely adjusted and no extra triggering number is needed to be added, and the LTD is applicable to large-scale LTD devices.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a linear transformer driver (Linear Transformer Driver, LTD) which uses electromagnetic induction to generate a trigger signal self-trigger switch to realize self-trigger. Background technique [0002] LTD is a new pulse power technology with the potential to become the next generation mainstream pulse power technology. Using LTD technology can generate high-power pulses with a rise time of about 100ns to directly drive the load without any pulse compression section. [0003] LTD consists of a switch and a capacitor (one-way charging) or two capacitors (positive and negative charging) in series to form a sub-block, several sub-blocks are connected in parallel to form a module, and several modules are connected in series through inductive superposition. If more current is required, multiple parallel connections can be used to build large-scale devices. The princi...
