<p>PROBLEM TO BE SOLVED: To provide a transformer device that can be reduced in size as a whole by reducing the size of a first transformer while the insulation performance of the first transformer is improved. SOLUTION: Each first and second transformer 2 and 3 of the transformer device is provided with a magnetic core 15 which is inserted into a bobbin 14 wound with windings. The transformers 2 and 3 are magnetically coupled with each other by commonly using the core 15 between the transformers 2 and 3. In addition, each transformer 2 and 3 is provided with a control circuit means which stops the function of either of transformer 2 and 3 while another functions.</p> |
