INVERTER TRANSFORMER

PROBLEM TO BE SOLVED: To reduce variations of a leakage inductance of two secondary wiring with no special wiring management such as space winding when a wind remaining part occurs in an outermost layer in a two-output type inverter transformer whose secondary windings are located on both sides of a primary winding. SOLUTION: The two-output type inverter transformer includes a magnetic core forming a closed magnetic circuit, a bobbin 10 on which two dividers 36 are installed on a cylindrical winding axis 34 having a flange 32 on both ends and terminals 38 are provided at ends of the flanges and dividers, a primary winding wound around a center spool portion divided by both dividers, and two secondary windings wound around a side spool portion divided by flanges and dividers. In the center spool portion, two separators 44 are opposed in the center separated by a width of a winding wire rod, a winding advance direction is reversed for a left-side space and a right-side space by the separator pairs, and a winding state is made to be symmetrical about the center.
