The advantage of IGBTs over BJTs is that device rise and fall time switching capability is 5-10 times faster, resulting in lower device switching loss and a more efficient drive. However, for a similar motor cable length as the BJT drive, the faster output voltage risetime of the IGBT drive may increase the dielectric voltage stress on the motor and cable due to a phenomenon called reflected wave. Faster output dv/dt transitions of IGBT drives also increases the possibility for phenomenon such as increased common mode (CM) electrical noise. Electromagnetic interference (EMI) problems and increased capacitive cable charging current problems. Also, experience suggests any pulse width modulated (PWM) drive with a steep fronted output voltage wave form may increase motor shaft voltage and lead to a bearing current phenomenon known as fluting. This paper provides a basic understanding of these issues, as well as solutions, to insure a successful drive system installation.","PeriodicalId":338656,"journal":{"name":"1997 IEEE Annual Textile, Fiber and Film Industry Technical Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123352172","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}

The definition of power quality or more specifically, a power quality disturbance, is generally accepted as any change in the power (voltage, current, or frequency) that interferes with normal operation of electrical equipment. It is the susceptibility of the end-use equipment that defines the necessary level of power quality. The intent of this paper is to present information on power quality issues as they affect end-use equipment. The goal of industrial customers is, of course, to stay competitive in the production of their particular product or service. One effective way of accomplishing this is to reduce downtime and thus production loss by limiting the effects of power disturbances. The goal of electric utilities is to maintain a healthy and effective relationship with customers while also promoting the use of electrical energy. It is essential that industrial customers and the utility work together to provide solutions to power quality problems. This paper defines power disturbances in industry accepted terms, examine the sources and effects of these disturbances (for both the utility and the industry), and explore economical solutions based on the compatibility of the equipment and the electrical environment.","PeriodicalId":338656,"journal":{"name":"1997 IEEE Annual Textile, Fiber and Film Industry Technical Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131288084","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}
