Abstract
PURPOSE:To prevent the operation of one transformer from affecting to the other transformer and to reduce the outside shape of a composite transformer by providing a common yoke part between the two transformers combined in a body. CONSTITUTION:A small composite transformer 11 used for a flash lamp for photographing, etc., is formed using E type transformer iron cores 12, 13 by a ferrite material. Further, coils 12, 13 required for a transformer for oscillation is wound around a central leg of one iron core 12, and coils 13a, 13b required for a trigger transformer are wound around the other iron core 13. Using the transformer 11 with this constitution, a yoke part is made to be common, and a magnetic flux phi12 of the oscillation transformer and a magnetic flux phi13 of the trigger transformer are made to differ in their generated time, thereby allowing influence on each other to be prevented. Further, in the composite transformer 14, a T-type transformer iron core 15 is combined with an E type iron core 12, and coils 12a, 12b for oscillation and coils 13a, 13b for trigger are wound around the iron core 12 and 15 respectively, thereby allowing the composite transformer 11 or 14 to be small in size.
