Abstract


For inverter as the research object, this paper proposes using GO methodology on inverter for reliability analysis, by comparing different reliability analysis methods, solves the problem that GO methodology is difficult to analog feedback unit when to do analysis of electronic products’reliability.The GO methodology is a system reliability analysis method oriented by success. It can analyze the reliability of the multi-state, related-time, complicated systems. Comparison with other methods,it is advantage in some special systems, especially in follwing system and sequence system. It has been successfully applied to the reliability analysis of large-scale system, but rarely applied to the small-scale system. Therefore, studying the application of GO methodology in small-scale system is of important academic meaning and practical value.This paper introduces the basic principles of the GO methodology. It introduces the origins and development of the GO methodology,explains the basic concept of the GO methodology, shows the process of setting up GO chart and doing GO computing. Then it makes out the reliability analyzing process of the GO methodology by a practical example.Inverter is a independent system, according to its character-ristics, this paper analyzes the main circuit of inverter using the status combination algorithm of GO methodology. It calculates the reliability parameters and all the minimal cut set of the main circuit. Then this paper analyzes the power supply circuit and the control circuit of inverter power source, using the probability formula algorithm of GO methodology. By general dealing with the result of analysis of the main circui,it calculates the reliability parameters and all the minimal cut set of the inverter. The reliability analysis results are important for improving the reliability of the current system, and offer academic basis for the fault diagnosis of the experiment system of electronic antiskid devices. Finally, this paper analyzes the main circuit of inverter using the FTA. And compares to the analysis results, GO methodology is proved to be accurate. It proves that GO methodology can be used in products of this type, and gives a new ideas to the reliability analysis of similar products and the change of GO methodology of application.
