IPC: H03H7/09
Filed: 1985-11-06
Abstract: PURPOSE:To obtain a coupling degree responsive to the number of turns of a shortcircuiting winding by providing a coupling core for coupling the first core with the second core, and providing the shortcircuiting winding in which both ends are shortcircuited with the coupling core. CONSTITUTION:When a current I3 flowing to a coil 3 alters, the number phi of magnetic fluxes of magnetic fluxes 30 changes, and an electromotive force l0 responsive to its timing change rate is generated in a shortcircuiting winding 11. A current I0 is generated by the force l0 in the winding 11, and a magnetomotive force F of a direction for disturbing the variation in the number phi of magnetic fluxes is generated. As a result, the variation in the number phi of magnetic fluxes is disturbed, the electromotive force generated in a coil 5 due to the variation in the number phi of magnetic fluxes reduces, the variation in the number phi of magnetic fluxes generated due to the alteration in a current flowing to the coil 5 is disturbed due to the similar reason, and the electromotive force generated in the coil 3 is reduced by the variation in the number phi of magnetic fluxes. Thus, the amount of the magnetic fluxes due to the magnetomotive force owing to an induced current flowing to the shortcircuiting winding reduces to decrease the degree of magnetic coupling of the first and second coils, thereby setting it to the value responsive to the number of turns of the shortcircuiting winding.
