Title:
HARMONIC WAVE REGENERATIVE TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2016/159526
Kind Code:
A1
Abstract:
The present invention relates to a harmonic wave regenerative transformer and provides a configuration comprising: an iron core comprising a first leg, a second leg, and a third leg; a high voltage-side U-phase coil wound around the primary side of the first leg; a high voltage-side V-phase coil, which is connected in parallel with the high voltage-side U-phase coil, and which is wound around the primary side of the second leg; a high voltage-side W-phase coil, which is connected in parallel with the high voltage-side U-phase coil, and which is wound around the primary side of the third leg; a low voltage-side U-phase coil wound around the secondary side of the first leg; a low voltage-side V-phase coil, which is connected in parallel with the low voltage-side U-phase coil, and which is wound around the secondary side of the second leg; a low voltage-side W-phase coil, which is connected in parallel with the low voltage-side U-phase coil, and which is wound around the secondary side of the third leg; a regenerative-side U-phase coil wound around the center of the first leg; a regenerative-side V-phase coil, which is connected in series with the regenerative-side U-phase coil, and which is wound around the center of the second leg; a regenerative-side W-phase coil, which is connected in series with the regenerative-side V-phase coil, and which is wound around the center of the third leg; and a band pass filter configured such that the output ends of the regenerative-side U-phase coil and of the regenerative-side W-phase coil serve as inputs thereto. The transformer, described above, has a tertiary winding, which can circulate harmonic waves, added inside the transformer and has a regenerative load connected to the output of the tertiary winding such that, by regenerating power generated by the harmonic waves, waste of power can be reduced.
