Abstract:
A noise reduction reactor is inserted in the power lines from a three-phase four-line
AC power supply and reduces noises transmitted through the power lines. The
noise reduction reactor comprises a first magnetic core having a through hole
at the center and forming a first closed magnetic path, first, second, third,
and fourth coils provided corresponding to the power lines from the three-phase
four-line AC power supply and wound around the first magnetic core, a second magnetic
