Abstract:
1. A power converting transformer, comprising: a substantially rectangular flat I-core extending along an x-y plane in an xyz orthogonal coordinate system; and an E-core including a substantially rectangular flat base portion extending along the x-y plane, a central leg portion installed upright at a center of the base portion to extend in a z-direction, and a pair of outer leg portions installed upright in opposite end portions of the base portion in a y-direction to extend in the z-direction, the I-core placed on the outer leg portions, wherein the I-core includes a pair of fixing grooves provided at centers on opposite side surfaces of the I-core in the y-direction, the fixing grooves extending through the I-core in the z-direction, the E-core includes a pair of fixing recess portions provided on a surface of the base portion opposite from a surface of the base portion facing the I-core, the pair of fixing recess portions provided at centers in the x-direction of the opposite end portions of the base portion, the I-core and the E-core are pressed and fixed to each other by a fixing spring wrapped around the I-core and the E-core through the fixing grooves and the fixing recess portions, and an x-direction length of the E-core is shorter than an x-direction length of the I-core, a y-direction length of the E-core being shorter than or equal to a y-direction distance between the fixing grooves of the I-core.
