Equivalent circuit is a simple and powerful tool to predict the performance of transformers. Depending on the type of application, different equivalent circuits might be used. The normal procedure to determine the equivalent circuit parameters of a transformer is to run no load and short circuit tests on the transformer. AC magnetic analysis is a type of finite element analysis which can help to get the equivalent circuit parameters of a transformer. In this course, different transformer equivalent circuits will be discussed, and their parameters will be estimated using AC magnetic analysis in EMS software. This helps to estimate equivalent circuit parameters before prototyping a transformer. Furthermore, this equivalent circuit can be used for voltage regulation of a transformer.
Mahmud Bijan received the B.Sc. degree in electrical engineering from the University of Birjand, Birjand, Iran, and the M.Sc. degree in electrical power engineering from the University of Tehran, Tehran, Iran, and a Ph.D degree in electrical engineering from Concordia University. His research interests include designing, modeling and fault diagnosis in electrical machines and transformers. Performance analysis, loss calculation and efficiency estimation of electrical machines and transformers are essential parts of his research. He is currently working as Senior Product Manager at EMWorks and focuses on electromagnetic finite element analysis of electrical devices such as electrical machines and transformers.
