<P>PROBLEM TO BE SOLVED: To provide an inverter transformer which can flexibly cope with a difference in required output number, and wherein the winding diameter of respective secondary windings is reduced to make a secondary-side bobbin smaller in size and the mounting area of a substrate can be suppressed. <P>SOLUTION: A coil set is comprised of a secondary-side bobbin pair that two secondary-side bobbins are coaxially and vertically overlapped, and a core which forms a closed magnetic circuit of magnetic flux penetrating the primary winding of the primary side bobbin and two secondary windings of the secondary-side bobbin pair. N sets (N=1, 2, 3...) of the coil set are placed side by side along the primary-side bobbin, and one or two voltage outputs are taken out from each of the coil sets. <P>COPYRIGHT: (C)2008,JPO&INPIT |
