摘要： PROBLEM TO BE SOLVED: To provide a transformer which is capable of obtaining high voltage and advantageous to attaining miniaturization and cost reduction. SOLUTION: When an input voltage V1 is supplied to each input terminal 1002, magnetic flux ϕ1 and ϕ2 (generated magnetic flux ϕ1 and ϕ2) are generated by two primary windings 14 independently to respective input side cores 18. Further, since the magnetic flux ϕ1 and ϕ2 pass along an output side core 20 through a connection core 22, the sum total of the magnetic flux ϕ1 and ϕ2 intersects a secondary winding 16. Accordingly, an output voltage V2 of the secondary winding 16 turns into the voltage based on the magnetic flux ϕ1+ϕ2. COPYRIGHT: (C)2008,JPO&INPIT
