<p>PURPOSE:To contrive miniaturization of the device and reduction of magnetic effects due to the leakage flux between adjacent transformers by forming plural bobbins combining divided magnetic cores provided with plural recessions, by winding and by forming plural mutually independent transformers. CONSTITUTION:A composite transformer 28 is made of plural transformers 31, 32, 33, 34, 35, 36, 37, 38 and 39, 40 winding plural bobbins obtained by combining divided magnetic cores 30a and 30b provided alternately with plural recessions 29a, 29b. The recession 29b is made longer, the winding positions of the transformers 33, 34, 35, 36 and 37, 38 are mutually shifted laterally, the distance between the adjacent transformers 31, 32, 39, 40 is made longer and the magnetic effects due to the leakage flux between the transformers are reduced.</p> |
