Quality Comparison Model and Method of DC/DC Power Modules for Torpedoes

Abstract

In order to effectively identify and select DC/DC power modules with great performance and reliable quality available for torpedoes, a quality comparison model of the DC/DC power module for torpedoes was proposed. The model was based on the working principle and failure mode of the DC/DC power module, with the faults during torpedo operation as the starting point. This paper summarized and analyzed the concerns that have an important influence on the quality of the DC/DC power module for torpedoes from the aspects of performance and function, structure and formation, design and development process, and quality assurance. Then, the related factors were extracted, and a general model of quality comparison of the DC/DC power module for torpedoes was constructed. On this basis, the comparison methods for performance and function, as well as structure and formation were studied. At the same time, the basis and method for the comparison results were put forward according to the comparison model and the application scenario of torpedo products. The research on quality comparison model, comparison method, and the basis of comparison results provides a system solution for selecting DC/DC power modules for torpedo products and provides support for the reliability analysis and guarantee of torpedo circuit.
