<p>PROBLEM TO BE SOLVED: To provide a power supply transformer with improved characteristics as a whole where the voltage fluctuation of a primary winding is small, copper loss is small, and there is no dispersion of the distribution capacitance. SOLUTION: This power supply transformer T has a secondary winding 12 that is arranged at a center part and a primary winding 11 consisting of winding parts a-f that are equivalent to the number-of-turns ratio between the primary and secondary windings installed in a symmetrical layout while surrounding the periphery of the secondary winding 12. With this configuration, the voltage fluctuation of the primary winding 11 becomes extremely small. Also, a distribution capacitance between the primary winding 11 and the secondary winding 12 is balanced and at the same time the increase in winding resistance due to proximity effect can be suppressed and iron loss can be reduced due to the symmetry of the winding parts a-f of the primary winding 11.</p> |
