Estimation of residual flux in single phase transformer using dynamic modeling of two winding single phase transformer

2017 International Seminar on Intelligent Technology and Its Applications (ISITIA), 2017
This study deals with estimation of residual flux in 1 kVA 1-phase transformer. Transformers used in the study have two type core cutting topology. The transformers were modeled with MATLAB software and then simulated to obtained inrush current. Experiments were also done in order to obtain its inrush current with different demagnetization time.

Single-Phase Power Transformer Formed Cores

Transactions of the American Institute of Electrical Engineers, 1950
For many years power and distribution transformer cores were built of hot-rolled laminations assembled into a core structure. When cold-rolled, oriented strip steel was introduced into transformers, new types of distribution transformer cores were developed.

Single-Phase Universal Active Filter Without Transformer

APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
This paper presents an universal active filter for harmonic and reactive power compensation in single-phase system. It is a combined system of a series active filter and a shunt active filter without use of transformer. The proposed system is suitable for applications where the size is a critical factor.
