Abstract
Based on power adding technology, the linear transformer driver (LTD) scheme is widely used to generate high-energy pulsed outputs and adopts a hierarchical and modular structure. Although robust design and fault analysis for basic components have been conducted recently, there is still a lack of enough reliability analysis studies of the whole system. Taking an actual LTD system as an object, this paper presents a system reliability model based on a load-sharing mechanism. A unified load-sharing rule structure is established and four typical rules corresponding to equal, linear, exponential, and local-equal relationships are discussed in detail while evaluating the impact of the load-sharing mechanism. Subsequently, simulation experiments are performed to illustrate the effects of different load-sharing rules as well as analyzing the system reliability in which we simultaneously propose a self-adaptive Monte Carlo simulation flow to achieve the sampling probability adjustment according to the random failure sequence. The simulation results can serve as a suggestion for further improvement of the system reliability. Moreover, the model framework and the simulation analysis method described here are universal and can be applied to evaluate the reliability of other LTD-based systems with tiny modifications.
Highlights
The linear transformer driver (LTD) is a rapidly developing technology used to generate pulsed outputs with the requirement of high voltage, high current, and high power
A hierarchical and modular structure is adopted in the general design process of the LTD systems [6,7], which decreases the inherent complexity of the system and makes it possible to conduct module maintenance, recycling, and reconfiguration
We have found that the more sensitive to the distance factor the load-sharing is, the more centrality within each levelthat is. the Besides, no matter load-sharing ruleload-sharing we adopt, there the simulation, we have found more sensitive to what the distance factor the is, theismore noticeable fault centrality within each level is
Summary
The linear transformer driver (LTD) is a rapidly developing technology used to generate pulsed outputs with the requirement of high voltage, high current, and high power. Since proposed by H.E. Daniels [16] to describe how the strain on yarn fibers increases as individual fibers within a bundle break, the load-sharing mechanism has been wildly considered in the system analysis process at various stages of the life cycle, such as load allocation strategy [17], maintenance analysis [18], and system architecture design [19].
