Abstract
Abstract An explosive flux compression generator is coupled to a high resistance load by a pulse transformer. Chemical energy is converted to electromagnetic energy and is transferred by means of the transformer to the high resistance load. The transformer allows coupling to a higher resistive load than is achieved with a transformerless-generator system having a current gain greater than unity.
