A Three Megavolt Transformer for PFL Pulse Charging

High voltage pulse transformer powered by low voltage capacitor banks have proven to be simple reliable systems for charging pulse forming transmission lines (PFL) up to the one megavolt range. A new transformer has been developed which will operate up to three megavolts in a PFL charging application. This transformer establishes the feasibility of multimegavolt operation and retains the features of compactness and high energy transfer efficiency that has been characteristic of lower voltage systems. This report includes a description of the physical features of the transformer, its electrical characteristics and a discussion of the operational results.
