摘要： A power generating transformer system (PGTS) where the core of the transformer has one of the generalized configurations is presented. Also, a power factor correction method in a power generating transformer system (PGTS) and a PGTS functioning also as power supply are presented. A PGTS generates an AC voltage with the frequency which lets the desired relative phase which is the difference between the phase of the flux at the primary coil and that of the flux at the secondary coil be in a specified range. And by controlling the reactive power at the primary coil of the transformer of the transformer circuit or at the location where the AC voltage is generated, the power factor correction is done using one or more components in the transformer circuit (TC). Finally, block diagrams of PGTS are presented.

摘要： In this work, it is shown for the first time that the power and the impedance in a transformer circuit depend on the phase of the flux, hence the phase of the current. There is a phase change when the flux travels the magnetic core, and formulas for the effect of the phase change in the power and the impedance are derived. Therefore, the power factor can be adjusted so that the power is delivered more at the load than that, at the primary supplied by the source.
