  • Patent number: 6066901
    Abstract: A topology for combining an array of low voltage, low current components to form a high voltage, high current pulse modulator. Each module of the MIA is composed of an inductive adder cell and a plurality of energy storage capacitors, a plurality of solid-state switches, and ancillary components to form a high current but a low voltage modulator. By using a large number of energy-storage/switch combinations in parallel, a highly redundant (reliable) module is formed. High voltage is obtained by inductively adding the voltage of a plurality of modules. Each module drives a single turn primary of a transformer (inductive adder cell). Each transformer has a single turn secondary. The single turn secondary of each transformer is connected in series. The advantage to this transformer topology (as opposed to a multi-turn secondary) is greatly reduced secondary capacitance which allows the transformer to operate at much higher bandwidth than otherwise possible.
