FERRORESONANT CONSTANT AC VOLTAGE TRANSFORMER Abstract of the Disclosure The primary and secondary windings of the transformer are each formed of a pair of independent windings, the first winding formed on the iron core of one of the phases and the second winding formed on the iron core of the phase adjacent thereto are connected to each other, and these serially connected windings are regarded as one phase winding respectively and are connected to each other in delta connection or Y connection. A variation in the voltage phase caused by a change in the load current of one of the phases has an influence not only on the phase of interest but also on the phase adjacent thereto and consequently enables the deviation in the phase difference between the output phase voltages due to loss of balance of the load to be decreased to about one half. When the leg parts of the iron cores of the two adjacent phases are juxtaposed and a common winding is formed on the juxtaposed leg parts so that one winding may function equivalently as two windings connected in series, the number of windings required in all is one half of the number of windings required where the windings are formed independently on the leg parts of the cores.
