چکیده
Abstract With the continuous improvement of technical level coal mine equipment, low-voltage converters have been used in many types underground electromechanical equipment because their energy-saving and high-efficiency features. However, mining generate a lot electromagnetic disturbances during operation, which may cause surrounding electrical to work abnormally. Therefore, it is important study disturbance characteristics frequency domain converter. This paper takes typical ZJT series AC converter as research object, models simulates whole its main interference source IGBT, analyses compares measured harassment data obtain trend IGBT converter, certain guiding significance for development immunity test standards or system around

Discriminant Analysis for ARMA Models Based on Divergency Criterion: A Frequency Domain Approach
The extension of classical analysis to time series data is the basic problem faced in many fields, such as engineering, economic and medicine. The main objective of discriminant time series analysis is to examine how far it is possible to distinguish between various groups. There are two situations to be considered in the linear time series models. Firstly when the main discriminatory informati...

متن کاملEfficiency Improvement of the Flyback Converter Based on High Frequency Transformer Winding Rearrangement
In this paper, a novel method for loss reduction and efficiency optimization of the high frequency flyback transformers is proposed based on rearrangement of the windings. According to detailed analysis of the high frequency flyback transformer using FEM technique, a novel and simple approach for its design improvement and loss reduction is introduced. It is shown that leakage flux scattering i...
متن کاملConvergence Analysis of EFOP Estimate Based on Frequency Domain Smoothing
The classic methods for frequency domain transfer function estimation such as the Empirical Transfer Function Estimate (ETFE) and cross spectral method do not work well when the noise signal is complex. Combines the time domain and frequency domain methods the Empirical Frequency-domain Optimal Parameter (EFOP) Estimate was presented. It could improve the precision of system’s transfer function...
متن کاملSaliency Detection Based on Frequency and Spatial Domain Analysis
As a component of low-level vision processing, saliency detection facilitates subsequent processing such as object detection or recognition. In this paper, we argue that a reasonable saliency detector should have the ability to: (1) Detect both small and large saliency regions. The size of salient regions vary greatly. When the salient region is large, however, because center-surround algorithm...
