These ground currents may cause an electrochemical corrosion of the storage devices. The damages caused by the electrochemical corrosion may acquire high values and may also disable the storage device out of the operation. This article deals with the measurement and analysis of the stray currents caused by the electric traction on a 3 kV DC electrified railway track in the area of Puchov (Slovakia). Each examined locality was analyzed and evaluated in the term of the electrochemical corrosion. Subsequently, the class of possible damage of the storage devices by the stray currents was determined.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124786794","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}

This current sensing technique utilizes low-side MOSFETs in three phase low voltage power inverters in order to estimate the phase current. The MOSFET parameters are highly temperature dependent, hence the realization challenges are made up. The proposed algorithm is based on mathematical model, in which temperature dependent characteristics of MOSFET like on-state resistance and body diode forward voltage as a function of temperature are utilized. All MOSFET parameters and characteristics can be changed, while the MOSFET is exposed extreme operation conditions. This effect is called the aging effect of MOSFETs. The MOSFET aging effect can influence the proposed mathematical model of current sensing technique, hence this effect is investigated and simulated in order to evaluate the reliability of proposed technique. The evaluation is carried out by means of simulation approach in the LTspice.","PeriodicalId":165069,"journal":{"name":"2020 ELEKTRO","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115391487","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}
