POWER-GENERATION COIL AND POWER-GENERATION COIL DEVICE USING THE SAME

摘要

PURPOSE:To provide a power-generation coil which makes the large size of a transformer inessential and to provide a power-generation coil device using it when the transformer is used to take out a large output as compared with an input. CONSTITUTION:A power-generation coil A is provided with a transformer 1 having a primary coil 12 and a secondary coil 13 and with an external magnet 2 formed in such a way that an N-pole is faced with an S-pole. The external magnet 2 is arranged in such a way that the direction of magnetic fluxes by the N-pole and the S-pole of the external magnet 2 is set to a direction opposite to the direction of a magnetic flux generated inside a primary-coil side-leg-part iron core 11a by the primary current of the transformer 1 and that the N-pole and the S-pole come respectively into contact with both end parts of the primary-coil side-leg-part iron core 11a.
