Abstract


The modeling of the Scott connection is typically formed by two single-phase cores at different turns ratio. For power rating about kVA orders and above, a three-phase core is preferentially used. This work considers the design and development of a didactic module for the Scott connection, where all terminals are available. This project is different because the building characteristic of the didactic feature with the possibility of multiple output voltages and the 3Φ-4Φ conversion using only one transformer. The transformer will be two windings to the primary side and four windings to the secondary one, allowing the 3Φ-2Φ and the 3Φ-4Φ conversions. Electrical parameters obtained by experimental tests, such as winding inductances and output voltages, are compared to those from digital simulations with OrCAD/PSpice software. Equations and fasorial analysis are also presented to describe module’s behavior. Palavras Chave - Conexão Scott, conversão bifásico-trifásico, transformador Scott.
