Advances in power electronics converters led to more efficient and controllable pulsed power supplies. Development of solid-state based topologies in pulsed power applications have been considered in recent years. Using these topologies gives compactness and easiness to EMF systems unlike conventional structures. The pulses magnitude and frequency of them are not the same as other pulsed power application. Therefore, most structures introduced are bulky and not efficient. This paper proposes a new configuration for pulsed power supply in electromagnetic forming system. The proposed system is based on Z-source full-bridge inverter that has the flexibility in terms of controlling energy and charging the capacitor to provide proper pulse for electromagnetic forming. In conventional electromagnetic forming systems, power supplies often don't have power electronics configurations. Therefore, the magnitude and frequency of the pulses are not controllable. Using solid-state structure can compensate these defects. Simulation and experimental results are included to verify the proposed system performance.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"458 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124333017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Signal processing converts the raw data into useful features to make the diagnostic operations. These features should be independent from the normal working conditions of the machine and the external noise. They should be sensitive only to faults in the machine. Therefore, providing more efficient processing techniques in order to achieve more useful features of the signal and faster and more accurate fault detection have been considered by researchers. This project applies the improved Hilbert-Huang Transform to decompose the signal into narrow frequency bands and extract instantaneous frequency and wavelet packet transform to remove the initial signal noise in vibration signal due to the broken rotor bars fault to achieve more useful features of vibration signals for the next stages of diagnosis. Comparison of Hilbert transform amplitude spectrum and detected instantaneous frequency by the Hilbert-Huang Transform and the improved Hilbert-Huang transform techniques and combining the improved Hilbert-Huang transform and wavelet packet transform indicate the superiority of the combined technique to detect frequencies of the fault.","PeriodicalId":414828,"journal":{"name":"2017 8th Power Electronics, Drive Systems & Technologies Conference (PEDSTC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127603178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
