Abstract

A method for transformer design with an asymmetric winding configuration to reduce the inrush current with appropriate voltage regulation and short-circuit current is proposed. Differing from the traditional symmetric winding structure in transformer design, this method can provide the high inrush equivalent inductance and suitable leakage inductance for a transformer. The formulas of the leakage inductance and inrush equivalent inductance are derived for the asymmetric winding configuration. Theoretical analyses showing the desirable winding configuration that the inrush current can be reduced to with appropriate voltage regulation and short-circuit current are presented. Using the inferential result in experiments, the inrush current can be successfully limited under a low voltage regulation and a suitable short-circuit current.
