Abstract
Abstract An electromagnetic transformer of special design which, when operated with associated circuitry, exhibits, during at least one portion of each cycle of operation, a lower interwinding capacitance than known transformers of comparable design. The secondary winding, or windings, of the disclosed transformer consist of a plurality of single layer segments, successive ones of such segments being joined through a diode in such a manner that, when a signal of a given polarity is applied to the primary winding of the transformer, the diodes conduct to connect the segments in series and when a signal of opposite polarity is applied to the primary winding of the transformer the diodes are cut off to disconnect the segments one from the other. In the latter condition the interwinding capacitance of the transformer is a minimum.
