Based on the data relevance analysis method, the distance value of the adjacent data subsequences in the one-dimensional sequence of the current mode Boost converter is measured, converts complex numeric columns to a simpler range value sequence, by means of qualitative observation and quantitative analysis, the working status of current mode Boost converter is identified and quantified. The design of an actual applied circuit has certain instructions.

Abstract. The original complicated array is converted into a simple distance of neighbor sequences based on the distance variation of boost converter, the chaotic state of boost converter can be detected obviously throughout computing Euclidean distance, the application potential of this method is worthy of great attention.
