<p>PROBLEM TO BE SOLVED: To obtain an integrated transformer device which can reduce noise, can be minimized and be made in a low cost, can be cooled for enabling an output capacity change, and which is integrally constituted of cores of the transformer, secondary windings, a choke coil and rectifying diodes. SOLUTION: This device comprises a pair of holding plates 7 and 8, plural cylinder cores 2a and 2b which are provided between the holding plates in parallel and around which primary windings are turned, secondary windings 3a1, etc., and 3b1, etc., which are provided on the internal and external surfaces of the cylinder cores, a choke coil 4 which is provided between the holding plates 7 and 8 and of which terminal is connected with taps of the secondary windings, and a pair of rectifying diodes of which each terminal is connected with both terminals of the secondary windings. The device is integrally constituted of the cores, the secondary windings the choke coil and rectifying diodes.</p> |
