The performance of the three-phase core type transformers, under AC/DC double excitation is discussed in this work. It is presented a mathematical model that considers the mutual coupling between phases and the magnetic ...

This work presents a new three-phase transformer modeling suitable for simulations in Pspice environment, which until now represents the electrical characteristics of a real transformer. It is proposed the model comparison ...

The effect of solid-state phase transformation at low temperature on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solidstate ...

In this work, the impact of the high-frequency transformer on the three-phase dual active bridge DC-to-DC converter operation is investigated, using four transformers with different connections: star-star, delta-delta, ...

The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
