<p><P>PROBLEM TO BE SOLVED: To provide a flyback transformer in which the ripple of a focus output voltage is small. <P>SOLUTION: A flyback transformer 1 is constituted by serially connecting first high voltage rectifier diodes 4a to 4g to the output sides of multi-divided high voltage coils 3a to 3g of a secondary coil 1b. A second high voltage rectifier diode 6 is connected to a coil winding start end of the secondary side coil 1b (the low potential side of a secondary side coil 1b). Breeder resistances R1 and R2 are connected to a first middle stage connection point 2a of the high voltage coil 3d in the middle stage and the cathode of the first high voltage rectifier diode 4c. Furthermore, a third high voltage rectifier diode 7 is serially connected between the high voltage coil 3d and the first middle stage connection point 2a in a forward direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
