High voltage transformer winding assembly with multiple frequency tuning

Abstract

A high voltage transformer winding assembly is disclosed which enables tuning to preferably provide a rectangular pulse output for improving voltage regulation. The winding assembly comprises a pair of winding subassemblies mounted on opposite legs of a magnetic core. Each winding subassembly is provided with a plurality of windings. The plurality of windings of the two subassemblies are interconnected to form a plurality of winding pairs. The interconnection is such as to form an a-c null or minimal a-c voltage substantially at the connection point between the windings making up a winding pair. When the start turns of the windings are interconnected to form the winding pairs the a-c null of each winding pair appears adjacent the core to reduce the likelihood of corona discharge. The plurality of winding pairs are connected in d-c series aiding by means of diodes which provide a-c isolation between the winding pairs. By selecting the spacing between windings of a subassembly and the height and width of such windings one of the resonant frequencies making up the output pulse of the winding assembly is determined in frequency and amplitude. Additionally, by selecting the spacing between subassemblies the aggregate leakage inductance and intersubassembly capacitance are altered to determine the frequency and amplitude of another of the frequencies making up the output pulse.
