Partial-core transformer design using reverse modelling techniques

Equivalent circuit components are developed for a partial-core transformer using a new technique called reverse transformer design. Components requiring special consideration include the core-loss resistance, magnetising reactance and the winding leakage reactance. Three sample transformers were built and tested in order to verify and determine the equivalent circuit parameters. A fourth transformer was also designed, built and tested. The measured performance of the transformer confirmed the validity and accuracy of the model.
