<p>PURPOSE:To lessen the voltage regulation with the desired output voltage by dividing a core into plural core parts of specified cross section, and winding a coil individually around each core part and connecting the windings in parallel. CONSTITUTION:A core 11 is divided into plural core parts AR2 and AR3 of specified cross-sectional areas, and a coil is wound around the core parts AR2 and AR3, and the windings 16 and 17 are connected in parallel. By winding coils on both of the two foot parts AR2 and AR3 and connecting them in parallel, even if the output current becomes great, the magnetic reluctances of the foot parts AR2 and AR3 are kept at an equal value. And the magnetic fluxes which respectively pass the foot parts AR2 and AR3 are kept at a fixed value so as to prevent the fluctuation of the output voltage. Hereby, even if it is difficult to set the winding ratio to a desired integer ratio, the desired output voltage can be obtained.</p> |
