ABSTRACT:
A high-energy high-efficiency electrical pulse transformer and a method of generating said high-energy electrical output pulses is disclosed.
A pulse generating system including a multi-phase pulse source is coupled to a load through a multi-phase pulse transformer. The transformer comprises a core of ferromagnetic material that has a plurality of legs, one for each phase, and input and output windings associated with the core legs and coupled respectively to the pulse source and the load. Output pulses are generated by exciting each input winding with an input pulse of the corresponding phase so that the input windings are sequentially excited, inducing a flux in the corresponding core leg and generating an output pulse in the corresponding output winding. Further, each leg is magnetically coupled to at least one other leg so that the excitation of one leg setting it to a remanence magnetic state of the first polarity simultaneously partially resets at least one other leg toward the remanence state of the opposite polarity. An electrical excitation control activates the multiphase electrical pulse source in a cyclic sequence so that each leg is substantially reset from the remanence state of the first polarity to the remanence state of the opposite polarity prior to the primary excitation of the leg in order to achieve a maximum change in flux and thereby maximize the energy transfer. The transformed output may consist of a series of discrete pulses, or may be timely sequentially summed to produce a smooth-topped waveform of power.
