MAGNETIC SATURATION SUPPRESSION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic saturation suppression device capable of suppressing the saturation of a transformer early.SOLUTION: The magnetic saturation suppression device 1, upon detection of an accident, controls a phase of an output current iout of a self-excitation type power converter 3 so that a magnetic flux of an interconnection transformer 4 is demagnetized.
