1. A reactor comprising:

  • a pair of coils;

    a pair of first iron cores disposed in parallel and respectively extending through said coils, each of said first iron cores being formed of laminated electromagnetic steel plates;

    a pair of second iron cores abutted against said first iron cores, via core gap spacers, such that a square-shaped magnetic path is formed, each of said second iron cores being formed of laminated electromagnetic plates;

    wherein one of said first and second pairs of iron cores constitutes an outer pair of iron cores and the other of said first and second pairs of iron cores constitutes an inner pair of iron cores, and said inner pair of iron cores is sandwiched between said outer pair of iron cores;

    wherein each of said iron cores of said outer pair of iron cores is a trapezoid-shaped iron core having four contiguous straight sides, two of which are parallel to one another;

    wherein for each of said trapezoid-shaped iron cores, one of said two parallel sides is a short parallel side and the other of said two parallel sides is a long parallel side which is longer than said short parallel side; and

    wherein said long parallel side of each of said trapezoid-shaped iron cores is disposed between said short parallel sides of said trapezoid-shaped iron cores, respectively.
