Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transformer for reducing noise.SOLUTION: The transformer has two iron cores 2, 3 in a tank 1 and windings 7, 8, 9, 10 wound around the two iron cores 2, 3. The transformer includes: a vibration transmission member 4 for transmitting vibration between the two iron cores 2, 3; and a phase adjuster 6 between the winding 8 wound around the one iron core 3 and a power supply 5. The winding 7 wound around the other iron core 2 is excited directly from the power supply 5. The winding 8 wound around the one iron core 3 is excited by a voltage obtained by shifting a wavelength by a quarter wavelength from a wavelength of the power supply 5 through the phase adjuster 6.SELECTED DRAWING: Figure 1
