<P>PROBLEM TO BE SOLVED: To realize a power supply module having a high degree of freedom with respect to its shape, while including a structure to connect a plurality of transformers in series. <P>SOLUTION: The secondary sides of first transformer modules 1NA, 1NB and second transformer modules 1RA, 1RB composing the power module 200 are connected in series. The first transformer modules 1NA,1NB are connected to the second transformer modules 1RA, 1RB so that polarities of diodes connected to the secondary side of a transformer 101 is reversed. Thereby, the external connecting terminal 162 on the secondary side serves as a high potential side in the first transformer modules 1NA, 1NB, the external connecting terminal 161 on the secondary side serves as a high potential side in the second transformer modules 1RA, 1RB. Thereby, a routing structure on the output side becomes simple and short, even if the rows of the first transformer modules 1NA,1NB and the second transformer modules 1RA, 1RB are not arranged on the same straight line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
