Description
Summary:Nowadays power transformers are considered among the huge and expensive equipment because of their massive iron core and heavy copper windings. Since the size of the transformers and the maximum power transition are reversely related, a new family of electronic power transformer has come into existence Which increase the transformer frequency, using power electronic converters. In addition to voltage transformation and good isolation which they bring about, these transformers are also associated with significant advantages, including considerable reduction in the size, power quality improvement, voltage profile improvement, etc. This paper attempts to introduce a new structure for Distribution Electronic Power Transformer (DEPT), using fewer power switches while maintaining the previous capabilities of the system. System performance and control strategies were successfully simulated in PSCAD/EMTDC and the simulation results are given below.
