PURPOSE:To simplify the transformer circuit by forming different sectional areas of input and output coils, telescopically providing a magnetic core at the coils and forming the variable power mechanism at the transformer itself. CONSTITUTION:Coils 4, 5 are coaxially wound on a pot-shaped magnetic cores 1, 2. Threads are formed on the outer periphery of an auxiliary iron core 3, which is screwed with the inner peripheral surfaces of the central hollow holes of the magnetic cores 1, 2 to be movably. The output of the transformer can be varied by moving the core 3. That is, the output can be altered by confronting the input coil pot-shaped magnetic core 1 and the output coil pot-shaped magnetic core 2 and elevationally moving the adjusting magnetic core 3 through the hollow hole 55 formed at the magnetic cores 1, 2. |
