<p>A magnetic-filed cancellation type transformer includes a primary winding wire and a secondary winding wire which generate magnetic flux when energized, and a core constituted by a magnetic leg portion about which the primary winding wire and the secondary winding wire are wound, and a base for fixing the magnetic leg portion. The primary winding wire and the secondary winding wire are alternately piled and wound on the magnetic leg portion, so that the direction of magnetic flux generated from the primary winding wire and the secondary winding wire are opposite to each other in any couple selected from among the pieces of magnetic flux, and the magnetic flux is cancelled out with each other.</p> |
